[Q] Hardware Id Missing?

"Hardware Id Missing - Windows cannot identify the device plugged into the SAMSUNG Mobile USB Composite Device. For assistance, contact the hardware manufacturer."
Why am i getting this error when I haven't done anything at all and it was working perfectly fine yesterday? I'm on a rooted GSM. So all my adb drivers are still setup properly i just checked.
Edit: it's working literally after i posted this but i didn't do anything... is there a solution to this if it happens again in the next like 2 minutes lol
further update: it just keeps going in out of this but mostly giving me this error than working anyone have a solution?

strange i just got an S III, getting the same issue. i going to try another PC i think it could maybe be driver related
Yeah works just fine on the other PC (both running Windows 7 x64) so im guessing driver related?

That's really strange, I mean i just installed the drivers last night to root my device and it all worked fine and i guess it decided to say "buzz off" to me the next day.. I think it's happening on a lot of other phones because I was googling earlier how to fix this problem but didn't really see anything on how to do it

Try reinstalling the phone with naked drivers.

im guessing you have a windows pc?
samsung put out a driver update for the computer that caused the error.
only way i found to fix the problem is to do a system restore back a few days before the update.
my update was automatic, im going to see if i can stop that update from happening for now..
ic you can call samsung and make them aware like i did...

I just got this message as well....and guess what, had just finished installing updates for Windows.
Any solid answer on how to fix this?

I see this when the debugging mode is on, if you turn off debugging the error goes away

I still get the error even after deselecting debugging.
Thing is, it was working perfectly fine with debugging on, until I updated Windows 7.
I think it has to do with someone with one of the security updates or something......really annoying!

I'm having this issue on my Galaxy Note as well. I started getting it once I updated from 4.0.3 ICS to 4.0.4.
I have to connect phone using the USB Mass Storage now. Before my phones SD and phone storage would be detected as soon as I plugged it in via usb.

Verified. Turn off debugging it works. When Debugging is on its random, but mostly does not work.

but turning off USB debugging kinda defeats the purpose of hooking it to your computer unless you're just using it to charge your phone

Try turn the usb tethering on, in settings guys

i've also been having this recently. i'm guessing that a windows 7 update has messed something up with mtp drivers as my phone was working fine across 3 different windows machines and now doesn't work on any of them :\ it has stopped appearing in explorer as a connected device in media or camera mode.

i turned this on and it forced the phone to install another set of drivers then i turned it off. now i can see the phone and access it in explorer in media mode which is all i care about. currently moving files, but unless i reply back stating otherwise, it's all good now

USB Teather
I was also having this issue. ive just tried the USB teather. It loaded RNDIS communication controller as a driver. No issues since. Good call with the USB tether. I dont know why I didnt think of that!
UPDATE not working this morning. Ive spent a few hours trying to figure this out, but alas.

S3 suddenly stopped being able to connect to computers

Hi there,
Not sure if anybody else has experienced this. Suddenly my S3 stopped being able to be recognized as a device by any computer. It will charge when plugged into USB. I have checked and fast charge isn't turned on. I have uninstalled the drivers from all my computers, I've tried this on a mac and a PC.
I'm on Task's AOKP Rom. But I have tried other Roms and the problem still persists. So I'm thinking it's a problem with my S3. Right now it's very annoying in that I have to always pop out my SD card to transfer files to my phone.

Did you check the oil?
Edit: I'm joking haha. But you might want to try another cable. It's almost always the cable.

The fact that you changed ROMs makes this less likely, but maybe you have a kernel that has Fast Charge on?

Probably not. Go to settings - USB Connection and check MTP. It works better than the other one.

Strange, I remember seeing that option on the stock TW rom, but I can't seem to find it in Task's AOKP rom, I noticed you're on AOKP too, would you mind giving a bit more detail on where that option is?

I know this isn't the perfect solution, but if you ever get yourself into a situation where the wire won't work and you really need to transfer files and you're on reliable wifi give AirDroid a try. Free app, that allows you to transfer files from a web browser. Saved me many many times. Sorry I can't help with the original issue!

I had the same problem with my stock/rooted ATT s3. Tried a multitude of cables and settings, but what finally worked was a bit of advice from another site. Power the phone off, pull the SD card, and try again. For me this worked. I do not have a good explanation why, but it ended a good bit of frustration.
Good luck to you.

Tried this and other -- nothing works

I've been having the same trouble, and tried this and other "fixes" (like in the thread http://forum.xda-developers.com/showthread.php?t=2049834) but nothing seems to work.
My situation is perhaps a little different, but this is what I know:
New Rogers SGS3 (I747M) - never rooted, or anything fancy
Plugged it into Kies the first time, and told me there was a Jelly Bean update
Did the update.
Now no computer will detect it - 2 PCs and a MAC.
I've installed and uninstalled drivers off and on for weeks
Tried Odin mode and Odin on 2 PCs
Doesn't even show up in the Windows Device list.
ADB doesn't see it (I assume because the driver doesn't see it)
Nada.
I only have one cable - the one that came with it.
People often talk of making sure it's in MTP mode, but I have no USB settings in my "settings" (JB is different?) though I think I can set it through the PhoneUtil suggested in the link above.
Created an account here (and watched the Noob video!) just to ask this question. All I can think of is that I must have broken something on the phone. Does anyone have any more suggestions or should I just take the phone back to Rogers and say it's broken?
Thanks a bunch!
Ian

Uninstall Kies
Uninstall Drivers
Reboot
Hook up the phone and let Windows Update get whatever drivers it can. It won't get them all
Unhook phone
Install the I747 drivers
Do NOT install Kies
Hook da fone back up

Still nothing

First and foremost - thanks.
But nothing happens. Uninstalled everything AND used the registry editor to get rid of everything "Samsung" and "Kies". I've now noticed, that I don't even get the windows "da-dump" when you plug a USB device in.
It seems there are no SGH-I747M specific drivers (are there?), just the "Samsung USB driver for mobile phones". Is that right?
So, I'm still stuck. The thing charges, but NOTHING else.
Any more ideas?

YOU sir are no geek. Only 1 cable? They are a dime a dozen now days. Even AT&T gave me a free one the other day. The good thing is that your back up and running. Again, why is it that it is most always the smallest thing that causes the biggest head ache?

woke up this morning to something weird. I have the appradio 2 which i use a mhl cord to connect to it. plugged it in like any other day and it wouldnt work. thought maybe it was a bad connection to radio but it wasnt. so i took it inside to plug into tv and nothing. so i plugged it into computer to see if it would connect and nothing. weird thing is, it charges but no connection to pc or anything. ive uninstalled and reinstalled drivers and nothing works. any help would be greatly appreciated.

Thanks for the response but that didnt seem to help.
I'm curious if its a hardware issue or something else. I've restored a backup i had to see if that helped but nothing. If i return to stock unrooted will that help? Or does someone have an idea as to why and how to fix this? Thanks for any help.

No idea. I did some searches for something like "android stuck usb charge only" and came up with the below. Some folks said that they were able to fix it, though not permanently, by wiping. The above seemed to work for some, though again, not permanently. I wasn't able to find anything else.
Did you try connecting to other PC's?
Did you try removing the device from your PC's device manager, uninstall the driver, then reinstall the driver and reconnect?
I agree it seems hardware'ish because it's also a problem with the MHL cord, too. I wish I could help more, but there's not much out there about being stuck in charge only mode.
Are you still under Manufacterer's warranty? Maybe that can be returned because it won't mount.?

Dont have another PC so that option cant be tested now. I removed the device and unistalled/reinstalled drivers and nothing.
Warranty is not an option because its past due. I do have insurance but am afraid of not getting an OG in return and i dont know how all that works to be honest.
I am willing to return to stock but only one concern i have is losing all my data. How do i backup pics and documents without being able to connect to pc? PLEASE can someone show me the way. Thanks again for all responses.

I started having this problem after installing the latest LG drivers. Replicated the issue on 3 different Windows 7 PCs. 1 32-bit home-built, 1 64-bit Gateway laptop with OEM image, 1 64-bit HP Laptop with work image.
Before upgrading, phone connects fine with in both MTP & PTP modes just using built-in (or pulled from WU) drivers. After upgrading to LG drivers, PC no longer detects the phone. Uninstalling the drivers or going backwards to earlier versions does not fix the problem.

Again,thanks to everyone for their responses, I really appreciate it. But unfortunately nothing seems to be helping my issue. I'm going by my wife's job to hook up to her computer to see if hers can recognize my phone, well at least I hope.
One thing I ask of someone, I've been using Arliberator to connect to my radio. Maybe someone has more knowledge than me to help.
https://play.google.com/store/apps/...51bGwsMSwyLDEsImNvbS5reWxlLmFybGliZXJhdG9yIl0.
Anyways, it has an option under settings to "fix drivers" which I have no idea what it does so i never messed with it. Except for when it wouldnt connect to the radio, I pressed it. Could that have anything to do with it not connecting to pc? I've emailed the dev of this app but have gotten no response as to what it does.
I'm really at a loss here as I can still use my phone but not to its full potential. Its frustrating because I cant even return to stock to see if it will fix my issue. Is there any other way to return to stock without a pc? Like can i flash a stock RUU? I ask because I once had an Evo 4g and was able to do it that way.
Again, thanks to everyone's responses.

I finally heard from the dev of ARLiberator and he guarantees me his app has nothing to do with my phone and that the "fix drivers" is for the app only. He says to try and reset my phone to try and solve my issue. But wouldn't that completely erase my phone?
Idk how I got here...

Your charging port may have broken a connector. Happened to my last phone. Charges fine but the computer connector won't work. Replacement needed bud.

[Q] External SD Card Reader

Well, hang me if I'm wrong, but I haven't been able to find an existing, relevant thread;
I have a 32x24mm class 4 SD card that, obviously, won't fit in my Arc. I'd like to be able to connect and use it on the device nonetheless, so I've hooked up a SD reader with USB, to a female USB/male micro USB cable, which then plugs into my phone's micro USB port. All goes well and the SD reader's light goes on, indicating it is functioning.
But for the life of me, I can't seem to find out how to actually access it from the phone. There's no relevant notification on the task bar, nor is there a directory I can access it through. Every thread I come across about an 'external SD card' invariably ends up being about the micro SD -inside- the phone, so that's no help.
Updated to the latest version earlier today, and have jiggled every cable. Every. Single. Cable.
Is it even possible to use an external SD card reader with the phone? I would be much obliged if someone could tell me what to jiggle.

Im pretty sure you need to install a kernel that has USB OTG supported.
Someone please elaborate lol i could be wrong

What ROM/Kernel combination are you using?
And if I am not mistaken, only some file explorer apps support USB OTG. Unfortunately, I cannot remember any at the moment.

Yeah, that seems to be it, on further investigation. I assumed the arc supported OTG out of the box, as it were. Most, if not all other phones seem to do, so that's probably it. I'm in the middle of aquiring an appropriate kernel and such, and I'll pop back in once it's done and tell y'all if it works.
Thanks.

I did this once, I had all my music on a usb memory stick and plugged in into my phone which then plugged into my car audio.
This was a while ago though but I do remember my phone getting distubingly hot!
I also think i remember reading that prolonged use of this can cause damage, ill have a look now.

[Q] PC won't recognize USB (no error message)

My Phone
Hi, Uber-noob here. I have the sprint samsung gs3, Model number sph-l710, android version 4.1.2. I had stock rooted my phone via QBKing77's video (thanks man!) and had had no problems, including connecting my phone by USB (PDA net, Odin, etc.) to my PCs.
My Problem
For no reason I can see, my laptop(s) stopped recognizing my phone. There is no message, the pc acts as though nothing was plugged in, no message. Device manager shows nothing either. The ONLY sign that my phone was plugged in at all is the "battery charging" icon on my phone.
What I've Done
I use a good data cable that used to work, and have bought and tried a new one. I have tried 2 other computers. I have reinstalled the USB drivers. I have pulled the battery from my phone, waited, and put it back in. I just did a factory reset. Nothing has changed.
I hope someone here can help me figure this out, cause I'm stumped. Please let me know if I can provide any more info. Thanks!

There is no s3 in my device manager. Device manager doesn't show, in any way that I have my phone attached. No message, no change, even after repeatedly scanning for hardware changes. I've plugged this phone into 3 different computers and its the same on each. Thanks for the advice though! Any other ideas out there?

Install the latest drivers from the Samsung website. This should solve the issue.

My Phone
Hi, Uber-noob here. I have the sprint samsung gs3, Model number sph-l710, android version 4.1.2. I had stock rooted my phone via QBKing77's video (thanks man!) and had had no problems, including connecting my phone by USB (PDA net, Odin, etc.) to my PCs.
My Problem
For no reason I can see, my laptop(s) stopped recognizing my phone. There is no message, the pc acts as though nothing was plugged in, no message. Device manager shows nothing either. The ONLY sign that my phone was plugged in at all is the "battery charging" icon on my phone.
What I've Done
I use a good data cable that used to work, and have bought and tried a new one. I have tried 2 other computers. I have reinstalled the USB drivers. I have pulled the battery from my phone, waited, and put it back in. I just did a factory reset. Nothing has changed.
I hope someone here can help me figure this out, cause I'm stumped. Please let me know if I can provide any more info. Thanks!

You said you tried a good cable, but is it the original cable? My phone is kinda wonky some times when I don't use the original usb cable.

Hi, it was actually the original cable that started messing up. The cable I have now was a replacement and I've had no problems with it whatsoever till recently. Thanks for the feedback though!

I would still try another cable because I've cables quit working out of the blue before. Also, it may help if you go to device manager and uninstall/remove your USB hub and then restart your computer...it will automatically detect and reinstall it.

I would try with a linux livecd/liveusb to rule out a driver issue. Also try a different cable. Or make sure your cable works - try with another device or computer.
And there really should be no need for extradrivers if you plug it in a mass storage mode. At least my two phones work with Win7, Ubuntu and Crunchbang otb.

Open Dialer enter ##3424#
When PhoneUtil Opens Select PDA
Tap Qualacomm USB Setting
Select MTP+ADB
Tap OK
Let me know if that does the trick

Hello, I'm not familiar with linux at all so that would be more of a last resort. However, I have tried multiple computers and a brand new data cable so that is not the answer probably. I appreciate the suggestion though!

That was a good idea! But it didn't work unfortunately. I'm starting to think that I may have a bad micro USB port in my phone. But the phone charges just fine, so I dunno. I hope you have more ideas? Thanks a lot dor the advice!

Yeah could be one of the pins in the port is messed up. Would explain why it charges, but no data connection.

I swear I tried every suggested solution out there – uninstalling and reinstalling drivers. Rebooting in download mode and trying to get phone and PC top lay nice. I accessed all those hidden settings and poked around with the settings. Three hours of tooling around the web looking for solutions and I got nowhere. Then I came across some obscure site where somebody suggested the pins might be off. With the care of a surgeon, I slipped the tip of a knife into my phone's USB port and nudged it every so slightly. Plugged and in and there was that elusive USB symbol, offering up all those grand options. I would've bet anything that this was some complex driver issue, but no. It was a slightly bent pin in that tiny opening at the bottom of my SIII. I'm not sure if I should be elated or annoyed at all the time wasted. I hope you guys find your own solutions, whatever they prove to be. Yeeeeeeeeeeeeeesh.
