[Q] Can't connect to laptop?

I got DHD 2 days ago, first day everything worked normaly, now I can't connect the phone via USB to laptop. I don't get the dialog asking to charge, use as disk etc. I tried everything, debug mode on/off, restarted, removed SD card and back in again, I used another SD card, reboot my laptop, phone (also with turned off "fast boot"), ... I've had HTC Magic till now, no problem connecting it as disk to my Macbook, same was with this one. I think I might have disconnected the USB too fast, but I'm not sure if it was this phone or the old HTC Magic. Interesting thing is, this topped working Thursday night, but on Friday I could connect it to the same laptop using Nokia's micro-USB cable, it worked, but no way to getting it to work with supplied HTC USB cable I could use Nokia's cable, but it's in the office and HTC's cable should work, shouldn't it?
Does anyone have an idea what to do? Phone does not even set the card so laptop can recognise it as USB disk (even if I use Windows VM, phone is not detected, i I plug in Magic, it works on Mac and Windows. Would a factory reset help (how do I backup data on unrooted phone)?
And yes, I've searched this forum and tons of other things online, nothing seems to work Some say this cable is for charge only, but a) how come it worked when I first got the phone? b) USB cable is a USB cable

Don't you have to pull down the notifications bar, tap USB connected and then choose the connection type you want each time. I don't have sense ROM anymore but I'm pretty sure that is what I had to do every time I connected the phone, I don't remember the phone prompting me.

+1..I'd say your phone is in charge only and needs to be changed as Quoted above.

Yeah, there should be an icon in notification bar, but there isn't. I have ticked to ask me each time, I've set default connection to disk, charge only, I've set it with debug mode checked, no difference

Make sure when you connect the phone is not locked this is how I got mine to work!

Of course, many times, with and without fast boot, I rebooted laptop even.

Have you removed any apps with Titanium Backup? Rooted your DHD? Flashed any custom ROMs/Radio's/Recoveries?
The ability to connect your SD card via USB to your computer is a core function included within Android. It would not suddenly stop unless you did something.
I'm also pretty sure the check box is for it to not ask you again. Have you looked at the USB settings to clear the default you have set?

No, my phone is not rooted (yet), it has stock rom and everything. And I've never set to "never ask me again". Weird thing is that it worked for first few hours.
Now, the WEIRDEST thing is that I just got to the office and connected the phone to my (same) laptop with Nokia cable. It works like it should, to every USB port I connect it to. So my official HTC USB cable, that came with the phone does not work, charges only while Nokia's USB cable (form my old E66) works perfectly. I can use this cable, though I'm ultra curious why a HTC cable wouldn't work?!

Faulty cable or a bent pin or something. Happens from time to time. Micro usb leads are dirt cheap and readily available now anyway so no loss apart from a little tone to replace it.

Yeah. I'll test coworker's HTC USB cable tomorrow and try his Desire phone with my laptop so if my cable is faulty, I'll go to service and ask for a replacement, a cable that comes with the phone should be under warranty, right? I will post the outcome here.
Not to forget, a huge THANY YOU to all of you who tried helping me

Yep, it was faulty cable. It took them 2 WEEKS go give me a new one, but at least it works (for) now.

[Q] Cannot install Windows 7 64 bit Drivers

I've tried everything I can possibly think of. I have an Asus Laptop with Windows 7 64 bit and absolutely cannot get my Epic to be recognized. I've uninstalled and re-installed the driver more times than I care to mention. I've tried mounting the device to no avail either. I've tried plugging in the phone into each of the USB ports on the laptop to no avail. I need to get the computer to recognize the device so I can get odin to recognize the phone so I can flash back to stock. Right now it doesn't do so. Does anyone have any ideas of what I can do to get this up an running?

Try installing the 32-bit drivers even if you're on a 64-bit computer....

The same issue comes up. It says that the drivers are not successfully installed (even though the installer goes through) and it says "Unknown Device" over and over.

Are you removing previous drivers?
then rebooting before installing new drivers...
also are you using stock cable?
if so buy a new cable you can get cheap ones online for like a dollar just search micro usb cables

Yes, yes, yes. Does the cable really make that much of a difference? I saw that people have had issues but I mean it charges properly all the time so I figured it was ok to use.

Absolutely!!!!!!!!!!!!!!!!!!!!!!!!!!!1
That cable is worthless get a Blackberry cable they are very durable and dependable.
i was having problems also..... all because of the cable.

I'll probably go buy a cable from Walmart, order a cheaper one online from Monoprice and return the other just so I can odin my phone...I really hope that's the issue though.

does it keep looping "unknown device" in the corner, almost like you unplugging and plugging back in repeatedly?
ifso try cleaning the contacts of the usb port on phone and on the small end of the cable.
if not then try totally uninstalling the drivers you installed and if possible when its saying "unknown device" open the device manager, r-click then unistall in there.
USBDview has always been able to dig me out of the home when ive had usb related driver issues... just run it and delete/uninstall anything samsung/android/adb etc related, reboot pc and phone then try again...maybe even redownload the drivers

http://firon.net/xda/usb_drivers_GalaxyS_x64.zip
update (you replied as i was typing): one bandaid for the cable you could try for now is to take a needlenose pliers or something and slightly squish the micro end to try getting a tighter fit.... i had to do that to the cable i keep at work.

You can always just download kies. That's what I did. When I was trying the standalone drivers I had trouble. Installed kies on both of my laptops and coding works beautifully everytime. And I seriously think you guys are ill. Its a cable... its digital. It either works or.it doesn't. I use my samsung wire exclusively. Its thin and I like contour on the plug. Both cables have worked flawlessly on both of my epics.

You are wrong.
Cables can have breaks in them which give them intermittent connectivity. Also, since this cable has several (5 I think?) single strands of wire in them, a single wire could be screwed up causing this (or the pin for a single wire on either end) That would still allow it to charge, and partially be recognized by Windows, but not allow it to fully communicate causing this problem.
I have a cable that I only use for charging because it has this EXACT problem. Another cable works perfect, but this particular cable gives me the unknown device.

Right.. so it either works or it doesn't lol if both cables are in perfect working condition then there would be no issue. Its all preference. I personally use a blackberry micro usb cable. It locks in to the usb port on the phone better. Just so im not paranoid about the wire coming off while flashing... cuz thats bad lol

I didn't articulate myself clearly, but that is my fault.
If a single wire inside the cable is broken (for the sake of simplicity let's just say it is the RECEIVE cable - from the device to the PC). The PC can recognize that there is a device there, but because the device can't talk to the PC, Windows can tell there is something there, but has no idea what it is since the device can't talk back to the PC. Also, in this scenario the cable would charge just fine since those individual lines are intact.

To quote u "Yes yes yes" it does make ALL THE DIFFERENCE... I had the same problem and made serveral posts about it when the phone 1st came out, I tried everything... Uninstalled/Reinstalled/Rebooted many times, Manually deleted the folders where the drivers are held then Re-installed, Installed Kies (which is a P.O.S. and was a BIG WASTE OF TIME imo.) I tried everything and just about gave up until 1 day i looked @ my roomate and asked him 2 let me borrow his cable to his cheap cricket phone 2 see if it would make a difference.
Well it worked... Get a new cable, if you've done what ive done and it still doesnt work, its the cable and not the drivers

I've done just about all I freaking can on this as well.
I've installed, un-installed, and re-installed the drivers. I'm running Windows 7 64 bit on Bootcamp.
I've used USBDView, I've uninstalled all of the connected drivers. They get re-installed, but the phone keeps keeps coming up as an Unknown Device. I try and locate the Samsung USB drivers directory, but it keeps coming up as Unknown.
Does anyone know specifically what directory I should use choose when trying to manually link the driver in Device Manager? I'm having a ***** of a time here.

Anybody have any ideas for me? Thanks.

I had the same problem. Buy a new cable from monoprice. The second I bought a new cable for my 64 bit Asus laptop it worked.
Trust me, buy a new cable.

I had the same problem. I didn't follow directions to solve my problem in Odin. I had to start Odin and plug my phone in and quickly put the phone into download mode. I did that a few times and finally got it to recognize. With Syndicate, it now recognizes every time. I say that now. LOL

This is how I fixed this problem. After doing all I could think of, uninstall, install, system restore, nandroid restor to when phone was being recognized... all these didn't work for me. I still got the same unknown device in device manager.
The fix: with samsung epic drivers already installed. Turn the phone on, plug into your computer. Let device manager find unknown device. Power off the phone. Boot into recovery. Pc will recognize your phone as samsung android device. Reboot your phone and you should be good to go. Hope this works for the rest of you. Good luck.

Isn't the original issue that the driver install fails? not that the device isnt being readed?

[Q] Windows 7 Doesn't Recognize my Continuum...

So I'm attempting to root the Continuum, but for some reason the phone won't effectively connect to Windows 7. For example, when I hook the phone up to my Samsung i7 laptop, all the phone does is charge. It doesn't even ask me if I would like to use usb storage or anything. The computer also doesn't recognize the device. Any ideas? Thanks!

A couple questions first:
- Did you install the Continuum drivers?
- Does your phone bring up the USB connection in the status bar?
- Does it bring up the Verizon VCast website on connection?

1. I likely did not install the Continuum drivers, and I have no clue where to get them. I'm assuming Samsung's website, but it's a bit hard to figure out and navigate...
2. My phone does not bring up the USB connection in the status bar.
3. When I go to the browser, it brings up the Verizon website with news, etc.
It should probably be stated as well that this phone is not activated. I am using it on wifi only for the time being because I traded it with a friend for another phone.

Alright, so I've figured it out. Strangely enough, I was just using a generic USB to microUSB cable, and I actually needed to use a Samsung cable. Weird, right?

So...now that I'm rooted, how in the world do I install a custom rom? I saw that there's a ClockworkMod Recovery out, but what does "Odin" mean? I'm coming from an LG Optimus V and have extensive experience rooting and installing custom roms and recoveries, but I've never heard of that before. Thanks again!

First, we dont have much for custom roms on this phone. The couple we do have contain fairly well written "how-to's" for them.
Second, if you are not sure, do some research and find out as many answers with the vast pool of knowlendge at your fingertips (the interwebs) as you can. There has already been a swarm of questions asked, and I am sure the answers may already be there for you.
I am waiting for the update and Froyo roms to come out before I bother with custom roms, but I am not holding my breath for that. I will probably be on my next Android phone before I will bother. Modding it up with Widgetlocker, ADW Launcher, and some other goodies at the moment to tide me over.

I had this same problem today. USB mass storage wasn't working, adb wasn't working. I wasn't using the samsung cable, but I can't see how that would make a difference, as the cable I was using has worked for literally a couple dozen different phones from different manufacturers - including other samsungs. I had the samsung drivers installed.
The owner claims that only media sync works on his computer as well, and that usb mass storage has never worked. Anyone have any ideas on how to fix this?

i am also getting this problem. as far as i know i am still using the samsung cable, as normal micro-usb cables dont fit in the continuums port. ill look for another one, but this is quite odd. what i have done (all windows 7 64 bit):
drivers uninstalled
drivers installed
lagfix on
lag fix off
factory reset (within adrenalyne's rom)
i am going to try to transfer the stock rom via bluetooth and see if that works
edit: turns out that isnt possible without odi recognizing the device, which it doesnt (not even in download mode). this is very peculiar
some more information: nothing even shows up in device manager. no unknown devices, nothing. the phone charges, but thats it. i might go to the verizon store and see if i can get another cable

My guess is because you are using a 64 bit version of windows..

Why would that matter at all?

The 64bit version of Windows 7 is notorious for not being compatible with a lot of devices. There just arent any 64bit drivers. If you dont understand how to run your software in the proper compatibility mode you will run into problems. I used the x64 version of Win7 for about 12 seconds after I realized my ancient usb optical mouse didnt work lol.
My advice, try running the Samsung driver installer in compatibility mode and see if that doesnt help.

Compatibility mode won't do anything in the case of drivers. I'm not sure what your issue is though as all of my Samsung phones have been picked up fine from within Windows 7 x64. Is the phone picked up on any non-Windows 7 computer? Have you checked in Device Manager to see if it just needs installed?

its the cable. i took mine to the verizon store, they tested it, and gave me a new one for free. works perfectly now

Excellent, problem solved!

So it turns out a factory reset fixed it. Using a moto cable. So that's definitely not the issue. Flashing froyo now. Thanks!

I have encountered that a few times also. Its weird cuz when I plugged the usb into ac charger it almost immediately asks if I want to mount sd for data transfer. 20 mins later I unplug usb from unit and plugit into my win7 pc and nothin? So plugged back into ac unit and it recognize....so I mounted and it didn't know what to do lol. I then plugged back intopc...waited...changed orientation and 'Boom' pc sees it...in fact I change orientation whenever it seems to hang and seems to work....
sent from my XDA phone - its more than a continuum

I should also note that I have never used a samsung cable and every usb micro I've used (moto,kodak,BB,Lg) has fit and worked. But I have noticed some usb related quirks since froyo update like no lock screen after charging till I push home button, inaccurate batt icon (goes from 3/4 to 1/4 in like 10 mins but overall batt life is same as before)...
On an unrelated note I also can't get v6supercharger to work...?

[Q] Galaxy nexus USB data stopped working (still charges)

My Nexus is stock but it is unlocked.
I have the latest CWM on there (touch 5.8.0.2)
I was currently downloading all the necessary stuff to flash to AOKP but havent even got there yet because all of the sudden my USB isn't working.
I have tried two different cables, the stock one and a different one (both which were working before).
I get charging working through USB but no file transfer.
I just did a wipe data/factory reset and wipe cache via Recovery, and still nada.
Am I cooked here? B-stock with no warranty from Expansys, now currently kicking myself for not buying brand new.
[edit] yes MTP and USB Debug were/are both checked on
[edit2] a lot of my searches seem to indicate that you can move and transfer via adb in recovery or fastboot while having this error. I am not finding that to be the case.
[edit3] windows 7 does not show any indication of a usb drive or anything plugged in as it used to before. This is obviously making it hard for me to try things like reinstalling drivers and whatnot.
thanks

It probably has nothing to do with the USB port...
Plug your phone into your computer, and then scroll the status bar down. You should see a notification "Connected as xx" Select that, then make sure connect as MTP is checked, if it's connected via ptp (camera) it won't allow you to sync files, for what reason so ever...
If that doesn't help, then reflash stock ROM, that usually helps.. With most problems anyway...
If both of these don't work, then I'm sorry, but I can't help you. I'd then call Samsung, and send it in...
LG Simon

Yea MTP was already checked on. USB debugging being on would have auto kicked in as well.
I flashed AOKP but still the same issues. The hardware might have gotten bonked - I hate how fragile these tiny little ports are!
Is there some kind of diagnostic I can run to see if it is truly a hardware issue?

It's the kernel, try another one

Just swapped to Faux kernel... still persists.
I'm really starting to think its the hardware but crossing my fingers there's a fix.

the same thing is happening to me, it started yesterday too!
I am on AOKP b-23, Faux kernel....
plug in my usb, it can charge but absolutely nothing happens on the computer side, try it on number of computers too... but the phone is able to charge.

Mine started doing this. Would charge‚ but sometime I couldn't transfer data or use adb. It seems that the USB didn't like to stay in my computer. Any little movement would unplug it just enough to keep it charging but nothing else.

I've since tested the MHL cable and also tried using the usb host cable to connect a mouse and both work... does that mean my data connection theoretically could be fine?

I'm using AOKP #23 with Trinity and not had this issue at all. Whether it's because I combine the ROM, Gapps and kernel before flashing I don't know but my phone is running fine

Had this same issue yesterday ( phone was 1 day old ) had it plugged into my windows 7 machine and all of sudden the machine couldnt see it. So I wiggled the cable sure enough the computer saw it, jiggled it again and it would lose connection to the PC. Tried this on several PCs with Several cables and same result everytime. If I held the cable connected to the phone at the right angle it would never lose connection.
Ran to Verizon and the numbskull behind counter tried telling me that is normal and I would just have live with it, almost punched him in the throat. Demaded he go get another phone and show me if that one does it. It didnt so he swapped it and was to hasty about it, ended up giving me another cable charger and headphones WOOT WOOT
new phone doesnt do it as of this writing

See http://forum.xda-developers.com/showthread.php?t=1427539 This is probably the issue you guys are experiencing. Seems like you should swap it in or try to fix it yourself by changing the USB charging board.

i'm an android dev and this has happened to me. really really not good to no longer have adb access to my device. restarted both the phone and computer and tried a different coworker's computer and usb cable with no luck.
i used a samsung usb charger last night which i usually never do (i usually just charge it on the computer) and now this morning i have no data connection.

Hello,
have this problem already on my GNEX. After some reading, i got an idea to turn off Fast Charge in Trickster MOD.
And MTP now working .
Anyway there is an warning about fast charge - " Enabling this will disable access to phone storage" .

Just so y'all know...Fast Charge is simply tricking your phone into thinking it's plugged into an AC outlet...rather than a USB port.
Thus MTP won't work.

same issue here
I'm having the same issue here. Charging works fine with 2 computers and multiple USB cables (as well as AC and car charger adapters), but data transfer has completely stopped working. My computer won't see my phone at all. I have the correct drivers (given that I used them to connect to my computer when I first rooted and unlocked the bootloader). Tried changing the drivers, but I can't get my phone to show up in Device Manager at all. MTP and USB Debugging are enabled.
The only thing I can think of is that I dropped my phone while it was connected, and now the USB cable only charges the phone if I bend it in a certain way (it usually requires upward pressure where the cable plugs into the phone to work). However, other USB charging cables work just fine without any pressure. Is there any chance that a new OEM Samsung USB cable might solve my problem? The other cables I've used weren't OEM.
I normally use a wi-fi data transfer app because the USB data transfer has been slow since day one, so that can be worked around. What IS a major problem for me is that I'm trying to re-root my phone after my root access was lost with the 4.0.4 OTA update. I didn't keep up with the news and only realized last week that my root access had been lost because I tried to do things that required root. Since the OTA update trashed my CWM recovery image, I seem to have no way to re-root and reinstall CWM aside from going back to my computer and doing what I did the first time. But if I can't connect to my computer, I can't do that. It also seems that I would need computer access to remove root in case I bring it back to Verizon for a replacement under warranty.
So on another note, if you guys know of a way to re-root my phone without connecting it to my PC, I'm all ears...

I have run into a lot of USB defects on the phones I have received. It might be wise to get Samsung to repair it, but you will be without a phone for a week. You could also try another cable.
I used to have similar issues except where the power got routed into the data port, frying my phone in multiple areas.
On Samsung's repair ticket they said REPLACED COMPONENT (I'm assuming this is the usb controller and port) this could be the solution but it requires sending it in.

No access to NEXUS with USB

I flashed my GNEX with SLIM ICS and ever since, I have not been able to access USB on the device. It will charge but I am unable to access the device. Even if I boot it into fastboot and plug the phone into my computer I don't even get a windows sound signifying the connection of a usb device. It just charges. I've tried all my usb cables (I have a ton!) and tried flashing other roms, but to no avail. I'm stuck and am gonna have to chance returning it if I can't get it to work on usb. Any help here would be greatly appreciated.
I wanted to add, in CWM when I go down to "mount USB storage" I get an error that states "E: Unable to Open ums lunfile (no such file or directory)

Go to storage and then press the menu key and select use computer connection and make sure mtp is selected.

Yes, I have done that.

Different computer, different USB ports (not the ones on the front, but the back)?

Tried 3 different computers at home, and a bunch of computers at work. I tried several different USB cables. The One that came with my Nexus One, the one that came with this phone, a bunch of random ones I bought at Amazon every once in a while. Tried in USB 2.0 and USB 3.0 ports, with no luck. I really think the clue with this is what I noticed in CWM, when I try to mount USB.

I've tried changing it from MTP to PTP and turning after switching between the two. I've tried two different roms, one based on 4.0.4 and 4.0.3. I've Tried several different USB cables, including the ones that came with my G2x and Nexus One. I've tried it in a USB 3.0 Port. I've tried using different kernals. Even when I get into recovery, windows still doesn't read somthing is attached. I've been transfering ROMS to it via dropbox. I don't think it's a rom issue as it should still show up in windows when in recovery. Also on those roms I made sure that they didn't have "USB Fast Charge" enabled, as I heard that can cause the issue I'm experience. Thinking it was an issue with CWM, I downgraded it, but still no USB. I'm stuck here. Any help is greatly appreciated.

turn debugging off

Debugging is off.

Their IS a fix for this, but we need the code to get into the PhoneUtil menu and turn USB back on.
It's an issue with Samsung phones apparently, and here's a fix someone found a while ago.

We just need the PhoneUtil code for the Galaxy Nexus and we should be all set.

I have found that the Nexus is picky about what cord you use. My girlfriend has an LG cord and my nexus won't even charge with it... Just a thought

Just to confirm, are you sure that you have the necessary drivers installed on the computer? If not, try this.

I have several android devices. And have used every single usb cable that is in my reach. I tried the Ones that came with the Galaxy Nexus. I tried the one that came with my Nexus One, I tried the one that came with my G2x. I tried about seven of the cables I picked up from amazon. I tried the one that came with my Acer Iconia A100. I even tried a few coworker's usb cables while I was at work. My friend has a Galaxy S II and I tried her cable, still no activity in windows. But it charges.
This is an issue that can only be solved by getting into the PhoneUtil menu on this phone. I've contacted Samsung and they refuse to provide it. They tell me to contact google or verizon. However I have the GSM International Version.

It appears that utility assumes that windows at least notices somthing. Windows doesn't even think I have anything plugged. I do appreciate your post, thank you for trying to help.

by any chance, does are you using a kernel with usb fast charge?? if usb fast charge is enabled, the phone is not recognised as a media device.

I'm having the exact same problem. I'll try turning off fast charging

Fast charging was off by default, or I turned it off in the roms I tested.

Their is a fix, but we need access to the PhoneUtil menu on the phone to apply it.

The code provided in their doesn't work on the GNEX.

What annoys me is that when I got the phone it was already rooted and I didn't have a chance to try it stock or back up the original. It was rooted with an older version, so I flashed 4.0.4 on it. Check out the reviews on newegg I'm not alone in reporting a messed with Galaxy Nexus.

Gnex USB connection issue solved
I was having same problem and tried different methods to solve the issue, nothing worked. so, i tried to remember what the recent cahange i have done to my AOKP rom.
That is Fast Charge, selected in rom setting. My usb has been sloved since I have unchecked Fast Charge in rom Setting.
PS. Don't forget to reboot.

reinstall drivers works most of the time.
