[Q] USB won't connect Phone to Computer - EVO 4G Q&A, Help & Troubleshooting

I cannot connect my device (EVO 4G) to my computer via USB. I have all the drivers, I have everything set correctly on my device and I cannot seem to make it work.
I cannot use adb wifi because I am not rooted, and I would like to root so I can get rid of this gingerbread 2.3.3 because it sucks. If you think you can help please do so I am dying here and nothing I find seems to be helping me and I would really like to get rooted again... damn insurance replacements.

Did your computer promote discovering new hardware when EVO 4G is pluged in?
Or do you mean your computer can find your sd card when EVO 4G is on disk drive mode, but can't successfully connect with a hecking software?

Do you have usb debugging on just a thought?

have you tried a different computer? What OS (operating system) are you running? Win 7 picks up drivers a lot better than say Windows XP. go to Start right click on computer and click on manage.. Go to devices, and check to see if you see a Android device driver on there. If you don't than either your usb is messed up or the os isn't picking up the driver. If you do see the device, uninstall it and replug your usb back in and see if it installs... Lemme know if that worked thanks

Change the cable. I've gone through several cables because of this exact same issue.

Or you could have the dreaded bad usb port.

Yep, same problem .
4 different cables, only one will recognize as "disc drive".

I have tried different cables, different PCs different methods only to discover my port was coming off of the board. Found a service locally that replaces them and I am good now. Very frustrating....
There are a few threads that discuss using ZRoot to attain a temp root for the sake of trying to fix the usb with adb codes. You may want to try this so you can use adb wifi...Example here
Hope this helps...

[Q] Laptop won't recognize phone

my computer does not recognize my epic anymore. I have the required drivers for it , but it keeps on popping up as an unknown device. I also made sure usb debugging was left unchecked. I have been trying to connect for a few hours now but still no luck.

What OS are you using on your laptop? If it's windows go to control panel and your programs add/remove (will vary depending on windows version) scroll down to "Samsung USB drivers" and click "uninstall", then reboot. Go to here and download the most recent usb drivers again. Plug in your phone, then install the drivers.
Post your results. Most likely it is not your phone, its a driver that has become corrupt on your laptop. Other possibilities are a bad USB cable or port on your phone.

Have you tried a different USB cable? Did you make any changes to your phone or PC just before it stopped recognizing it?
I had to use a usb hub with a power source for my laptop to see the phone.
Dell D620
Samsung Epic 4g
same thing on my pc. I keep getting USB Mass Storage Device Failed Error Code 10. started happening after the first push of froyo. im running Windows 7. very frustrating.
Epic thread revival!
I'm having a similar issue with my Epic. Both my laptop and desktop will recognize my phone as "Samsung CDMA Technologies" However, I can't do anything with it except charge. What's particularly bugging me is
A) Wired (USB) Tether won't work
B) Can't mount SD card through the phone
Laptop Specs:
Windows 7 Ultimate 64bit
Linux Mint 11 64bit (I'm having the same problems with Linux)
Phone Specs:
Epic 4G (SPH-D700)
Syndicate ROM Frozen 1.2
EG22 Moden
Genocide 2.0 Kernal
Here is what I've tried:
Toggled USB Debugging (both on and off)
Used Premium Micro USB cable in addition to stock cable
Uninstalling and Reinstalling drivers
used different USB ports
rebooted phone and computer
It should be worth noting that my phone seems to think everything is a-ok. Wired Tether app doesn't report errors, and when I mount SD card, there is no error either and the phone proceeds with the "USB storage in Use" message. My computer (regardless of which OS I boot) seems to think my phone doesn't exist, unless I'm doing admin type of things, such as flashing via Odin.
Normally, when I had my previous Epic (SRF 1.0.1, EC05, Twilight Zone Kernal), before it was stolen, Wired Tether worked perfectly, especially with Linux (connect as "AutoUSB 0"), and I could mount my SD card.
Suggestions?
Go to control panel and have it update drivers from Windows Update. Takes a long time to get them all.
I get the feeling it's more than a simple driver issue. I have the same problems with Linux, and linux has native drivers. And Windows Update is useless. It can't even find drivers for my fingerprint reader. Nevertheless, I will try it next time I'm on my laptop. Windows on my desktop is fubar.
I had the same issue with my pc.. I ended up using an old vista lapptop and everything worked perfectly.. sometimes these pc's just straight out don't work with these drivers.. wish I could help you out more man

Maybe dialing ##8778# and selecting modem mode under the usb section will help automtically install drivers.. see if that works, it helped me out for the whole epic to boost mobile process

Galaxy SII not recognized by computer

Installed the tmobile samsung galaxy SII USB drivers , I am using windows vista and it does not recognize the phone. I tried another vista computer it still can not recognize it. I tried an XP computer, it still can not recognize the phone.
How do I fix this?
Tried using the USB utilities under settings --> wireless and network
Still no luck
any suggestions will be appreciated

since you install the drivers into multiple computers and tested them all... it might be your phone.
First can you give more detail on what happens when you plug your phone in? Does your computer make any sounds or searches anything?
ALSO Try installing kies.
if that doesn't work either... looks like you need a warranty exchange
Try using an oem Samsung usb to micro usb cable. I had this problem with my Samsung Galaxy Epic a while back. Everytime I used a generic cable lying around my computer would not recognize my phone. When I used a Samsung cable it worked. Your computer should automatically identify your phone using the right cable. If not re-install them and don't forget to restart your computer before attempting to connect to your computer again. Good luck.
I've had this problem too.
Initially I had kies installed and had to launch the program to access the two 'mounted' removable drives.
I assume the drives mount, but you can't access the drives?
If that's the case, look on the phone and pull down the status bar and check to see if it sees the USB connection. Select that, and allow it to connect as USB storage.
thanks guys for all the quick response.
The problem seem to fix itself. After removing and attaching the USB cable a number of times, the PC suddenly recognized the phone.
I don't know what fixed it.
Now, I can proceed to root my phone!

you probably didn't give it enough time for the pc to actually install the needed components.. it takes a good 5-10 mins for everything to finish installing
I'm faced with the same problem. Only different is, as soon as it shows connect to usb from the notification bar if goes away. I tried the usb tool in wireless but still wont work. I tried the samsung cable as well
know it sounds dumb, but have you rebooted lately? mine wouldnt recognize the sd card when plugged into comp....rebooted....all is well

S4 not recognized when plugged in via USB

The device acts as if it is being charged.
Steps I have taken so far:
-uninstalled T-mo Samsung mobile drivers and reinstalled
-deleted (uninstalled) ALL recognized USB devices via USB deview
-tried to connect without Samsung drivers installed and all USB devices uninstalled
-tried to connect with Samsung drivers installed and all USB devices uninstalled
-tried to connect without Samsung drivers and other devices installed
-tried to connect using safe mode, both with drivers installed and not
---**these are both trying with the current one provided on Samsung's site (1.5.14.0) and with the one found here on XDA from 25apr2013 (1.5.23.0)
-tried to connect using different USB ports
-tried to connect using a different USB port on a different USB controller altogether
The kicker:
Device is recognized instantly... on my laptop.
This means:
-It is not the USB cable I am using (even though I have tried 3 different cables altogether regardless, including the one that came with the phone)
-It is not the device itself
Possible: Windows issue? Last time this happened was long ago when I had gotten a MyTouch 3G Slide. I eventually just reinstalled Windows since I had been meaning to then. I don't want to do it now though because I have too many things installed on here to start a fresh install... but I suppose if nothing else works, that's what I'll have to do.
Before that though, I would love to hear any other suggestions from anyone here.
Some time the fault cud be the cable itself... I had same issue months ago my original samsung UsB cables didn't worked... It olwyz show the msg UsB not recognized... Then I tried with a different UsB cable (i had a Nokia UsB cable) and it worked...
Try it...

As stated, I have tried to use two other USB cables aside from just the one that came in the package.
Since all cables work on the laptop, but not this computer, I have pretty much singled it out to be a windows or a driver issue. :\
What are the specs of your desktop and the specs of your laptop? You claim it is a windows issue so I assume your laptop (that recognizes the phone) is not windows? Do you have Kies on the PC? If so, try to uninstall it completely and then install the individual drivers. Also, maybe just try updating Kies. You wouldn't need to install it, just download to your PC should work. As far as that goes, does Kies recognize the phone when plugged in at all? Does ODIN recognize the phone when plugged in? Maybe some of this will help you to find out if it is a driver issue or not. Good luck.

PC is i7 920, 12GB DDR3, Intel x58
Laptop is i5 2430M, 6GB DDR3, Sandy Bridge
Both are Win7 Pro, neither have Kies (I always just downloaded the drivers themselves) but I'm downloading it now to give it a try. As of now, nothing recognizes the phone on PC.
Kies method didn't work either
I did "Troubleshoot connection error", which I guess reinstalled the driver, but it still didn't work.
Getting ready to dig out that Win7 Pro CD at this point... :\

Enabling dev options and USB debugging was the first thing I did once I turned on the phone. Tried it both with and without, still not recognized either way. Still recognized on laptop.
I've also reinstalled windows altogether, since that fixed my issue last time around, but it's no good this time still. Clean install, formatted. No good. Previous steps from first post also taken, still no good. Tried the PDAnet method as well, no good.
At this point I am wondering if it might be an x58 issue, which would really suck, but it's the only thing I can think of given all the steps I have taken.
Okay... so what's the trick on getting Windows 7 x64 to recognize this device in Download Mode?
I have enabled USB Debugging. Tried several different ports on my Maximus V Extreme motherboard. I have tried using the PDANet drivers. Nothing works.Windows will prompt me with the "Device Driver software was not successfully installed" message. Anyone know a trick?
EDIT: FIGURED IT OUT. The last Android device I owned was the Galaxy S2. Now, back then it was understood that one should avoid Kies like the plague. However, in this case, it solved my problem. It installed all necessary drivers and I was able to communicate with ODIN. Cheers.

I might have pinpointed the issue!
I tried Kies again, uninstalled, reinstalled, updated. No go. I did Kies by air and got a connection! So It's gotta be something with the USB.
Although I thought it was weird, I think it might be an x58 issue, I decided to pursue that anyways.
I found out that USB issues are common with x58 (per this forum: http://www.evga.com/forums/tm.aspx?m=159610 ) and will be trying a fix located here: http://www.evga.com/forums/tm.aspx?m=442244&mpage=1
I'll report back once I try this out. Hopefully it fixes it.
If not, I just ordered another USB 3.0 controller (completely unrelated, it doesn't need to be USB 3.0, just a different controller altogether, but USB 3.0 is backwards compatible anyways. I just needed one for blackmagic) which was PCI-e x1 (still dependent on x58, so it wouldn't have mattered, check diagram on fix link), which I WAS going to install in my PCI-e x1 slot, but that would have not worked! Going to install in a PCI-e x16 and hope for the best.
I'll reply back once I test that out too.

In case anyone was wondering or stumbles upon this later, I have a few updates.
I got the USB controller today and plugged it into the PCI-e x16 slot, plugged in the S4 and it worked completely fine.
I also contacted EVGA about the issue and will get an RMA, so perhaps it's just a faulty unit. However, this seems rather common (refer to previous linked threads) in x58 chips.
I imagine it has something to do with power distribution with the controller, which is why upping the ICH voltage fixes it for some people. The USB controller is powered via 4pin, not dependent on Southbridge. I guess the S4 has higher voltage(?) requirements for it to be recognized. It seems rather strange since my other devices are still recognized, but well, that's what I managed to come up with.
Cheers.

Here's my craziness.
USB connection was working yesterday. Today, it is not.
I have uninstalled/reinstalled the Samsung Windows drivers/Kies
I have even adjusted my southbridge voltage to 1.2V in my BIOS
Still, no joy.
Curiously, when I boot the phone into download/ODIN mode and connect it, ODIN recognizes the connection. Reboot back into normal mode, and no USB connection is recognized. It is not showing up in my Device Manager as an unrecognized device. It just doesn't know it is there (unless phone is in download mode).
UPDATE: Solved. I had installed this ROM (http://forum.xda-developers.com/showthread.php?t=2261013). Reading back over the thread, it provided instructions for re-enabling the USB recognition of the phone. Had to re-enable the developer options and reset USB debugging. Makes sense now.
HI
I'm facing this issue today, I've tried two different laptops, both have Windows 7 x64 installed. I've tried every USB port on the two machines, I've tried with three different cables, I've downloaded and installed every USB driver there is. no use!
I'm out of options here and I can't think where to look further.
any help please?

ok so now I'm guessing it is not windows, I tried on another machine with Windows Vista and got the same error.
any thoughts, anyone?
Did a factory reset for the phone
no it works!
don't know why
I just picked up this phone a couple days ago and last night tried to get the USB to work with no luck. I've tried everything I can think of. It does work in PTP mode but not MTP mode. I was able to use odin to on it though, so I was able to root it.
I've tried both in linux and on windows xp. I've never had an issue with any phone on linux and have installed/removed drivers numerous times on XP.
Tried 3 different cables, Factory reset with and without USB installed, tried pretty much everything I could find while googling similar problems (removing old registry entries, installed media player, etc)
I have adb installed on my linux box and even with debugging enabled I can't even get adb to connect to the phone.
Definitely something strange going on. Maybe I'll switch to cm10.1 to see if that makes a difference
I cant get my computer (windows 7) to connect with the phone when the phone is on, and was hoping some one might have found a fix.
This might fix it...

Here's a link with a list of things to try what you may not have tried to fix your problems.
A small number of devices I have worked on have a weird thing, that the first time I plug the cable into the computer, it connects but won't show up on the screen. unplugging the USB cable from the machine for maybe 3 seconds, and reinserting makes the connection work... go figure! :>)
Aloha and Good Luck!

Windows won't recognize t989

Hello all!
First: I promise I searched the forums and google as hard as I could!
I'm running AOKP JB with CWM, although the problem was present on stock ICS from T-Mobile.
Symptoms: Computer and phone will refuse to acknowledge any connection (nothing shows up in Device Manager), except the phone will still charge. If I do the "remove the battery with USB plugged in" trick, the first time I do it, it will recognize an unknown device, but kies and adb won't recognize it. If I unplug it and plug it back in, it'll go back to not acknowledging any connection.
I previously programmed it (when I was still running stock ROM) via ADB via WiFi, but I need to be able to use ADB via USB. Besides, I can't seem to get ADB over WiFi anymore.
When I plug it into a different computer (Win7), it will, however, recognize my phone.
Earlier this year, before I ever tried programming via WiFi, it connected to my Win8 machine with no problem. I don't think it's a problem with the wifi setup though because the ROM was reinstalled and of course I've restarted ADB in USB mode in the months since...
What I've tried:
Reinstalling Kies
Reinstalling Samsung USB drivers
[^]Restarting the ADB server
Updating ADB
Trying different USB cables
Trying different USB ports
Toggling USB debugging
Toggling MTP mode
The UART thing from the dialer
Restarting the phone and the computer (of course)
Checking to see if my computer's USB drivers need to be updated
The android terminal command "setprop persist.sys.usb.config mass_storage,adb"
Pulling and replacing the battery while connected via USB
Crying in a corner
If anyone can help me, it'd be greatly appreciated! I'm all out of ideas and Google is no longer helpful =/
try to uninstall the drivers that are present anything samsung related to your drivers ... then connect the phone and let the process do its thing if you have the samsung drivers saved on your PC and the drivers still aint working update the drivers and then manually click where the drivers are to install them and hopefully it will work and when you tried MTP is it the only option it gives you no storage or anything ??... and is usb debugging on when you are trying all this ??

I tried on my work computer that didn't have any samsung drivers and when the "unknown device" dialog popped up it didn't do anything or install anything, nor did it show up in Device Manager. Unplugging and replugging it back in did not reproduce the dialog box. Togged USB Debugging and still no dialog box saying it recognized it.
The thing with the samsung drivers is that they're self installing so even if it popped up in Device Manager, I wouldn't be able to manually update the drivers =/
I tried MTP both with and without USB Debugging, although it also gives the option for PTP.
At this point do you think I should unroot and go back to stock? It's not been recognized on three computers now! =[
Are you using the stock cable? My computer wouldn't recognize mine without it.

Both the stock cable and a generic cable.
Similar problem
Similar problem as the OP. And hi guys, it's nice to be on these forums.
My device, when I plug it in using the stock cable, doesn't even charge. It doesn't show up in device manager, nor does it give me a notification, or say it's unsupported and bear that yellow icon. I have tried using different USB ports, I have tried the toggling USB debugging, I have tried restarting phone, computer, and taking out battery. I have tried that PDA/MODEM dialer trick. I am using 4.1.2 Jellybean, not rooted. (that WAS my goal,, until I hit this roadblock) I have not connected it to the computer in the past, it's relatively new. I'm thinking the cable is bust.
Any suggestions would be appreciated. It charges fine through a wall outlet plug, be it generic or stock.
so guys ive come to a conclusion i think its something in the samsung usb cables try getting yourself a blackberry usb cable , TRUST ME !!! ever since i got my phoness etc... tablet and yadi yadi samsung usb cables have always seemed to give me problems i think its because they are multi data/charging cables and when using the blackberry usb cable i have never ever once encountered a problem with any of my phones sd/storage problems do yourself a favor and pick up one of those cables and you will be golden !! if not then i guess im the only lucky one :LOL here you go http://www.amazon.com/Blackberry-Travel-Adapter-Micro-Cable/dp/B004VMVSYK/ref=pd_sim_cps_2 5 bucks!
Edit also one more test boot into recovery and click in the advanced menu and see if mount usb works for you in recovery mode ??
FIX (try using a generic cable)
I actually solved it on my own! After borrowing a generic cable from a friend it booted up! The Samsung cable was just not doing its thing.
yeah im telling you those cables they provide are JUNK!!! i only use my samsung to charge because they do that well but data they are str8 CRAP!! glad you got it up and going
OP
Hope OP will have the same luck as me...pray to the Android gods...

Phone not Mounting on PC

So my phone was mounting fine on my pc, and then all of a sudden it wasn't. My Nexus 7 still mounts properly and accepts developer commands, but the m8 won't (yes developer settings is on).
I tried wiping and flashing a rom clean and it still doesn't work, charges fine though. Any advice?

You might try a different cord.
Open Device Manager in Windows and then plug the phone in. Do you see it in the list with a little yellow triangle? Do you see Android USB Devices listed?
OP after literally messing with various driver files, 8 usb ports and 2 laptops, I dug out my old box of cables and found a taped up, on its last limb OEM HTC EVO 4g (not lte the original) cable. This thing has been through the ringer. But its exactly what It needed. I figured with the 3 cable I had already tried this wasn't the issue, but have you tried using an OEM cable? I guess that is all that works. Good Luck

Still trying to get it to work, have tried 4 cables myself. I might just end up having to return the phone.... Fastboot works in bootloader

Uninstall all HTC drivers and HTC Sync. Then connect the phone. DO NOT choose the option to automatically install any drivers.
Open Device Manager, find the phone. Select the option to manually pick the driver, and select the generic MTP device driver.
This is what worked for me, after countless attempts at re-installing various HTC drivers, different cables and ports, etc.
Bump. Still looking for answer to this. I have RUU'ed both to Sense and Google Phone editions and the problem still persists, the phone does not detect its connected to a computer and change to mtp accordingly. Only way I was able to get the RUU in there was through fastboot, which is again the only time I can access the phone through usb. Adb is no luck in either android or recovery.

Have you tried revoking the USB debugging authorization and then accepting the RSA fingerprint key again when connecting to PC?
Obviously it can't be an USB cable problem if you can connect to it in bootloader mode and use fastboot commands.
To clarify, the phone just charges when connected, it does not detect that it is connected to PC so debugging doesn't even trigger, neither does mtp. I don't even get the slow charging notification
Does it do the same when you plug it in and reboot the computer to "pick up" during boot up process? Or if you run a live CD? I never had an issue like that with my phone but I did have a similar problem with the USB external blu ray drive I bought some time ago. The pc just didn't detect it at all not on any of the ports until I rebooted my PC with the drive already plugged it and for some reason it picked it up. <Not a solution as I don't know what caused it to not be detected in the first place but still...
Not sure if it's an issue with the device(Phone for you, blu ray drive for me) or if it's a problem with the PC even though other things might still work for you as it definitely did for me(phone, headset, mouse, keyboard, usb extender + all the external hard-drives connected to it)...
Problem exists in all computers, Mac, pc, linux
Did you try what I suggest in Post #6 above?
This worked for me when I had the same issue. adb and fastboot would work, but it would not mount MTP.
And just in the last day or 2 I helped someone else with the same issue and fix.
The phone doesn't show up in device manager.
Have you modify the Kernel? (Applying some settings for example)
I browsed over the web for this issue and found some people with the same problems. They solved by removing the settings applied on the kernel or flashing a new one.
I've flashed various kernels and ruu, still same result
Still looking for help
