For some odd reason, I lost adb functionality (i.e. any adb command issued receives "error: device not found"). I looked in Device Manager and noticed that MyHTC was gone! I looked at my phone and USB debugging was enabled and in charge only. I could put it in USB Drive mode and the PC would recognize it as a USB Mass Storage Device so that I could exchange and view files but no adb.
I searched and searched on this issue for hours and installed over a half a dozen "androidusb.inf" driver files several times over. Every install generated the Code 10 error where Device Manager was lacking some information from the driver file and could not start the device. I reinstalled HTC Sync and gave that a try...nothing. Downloaded USBDeview and uninstalled all HTC drivers including the HTC Android USB Device and tried again to no avail. WTF?! What else am I supposed to do?
Well, in a "what the hell, let's give it a try" kind of moment, I decided to toggle the USB debugging off and then back on (and yes, it was checked and on the whole time). WORKS!!! WHAT THE CRAP?!! MyHTC is back in Device Manager and everything is back to normal. I'm glad but irritated!
I share this story in hopes that if someone else stumbles on this problem, they will not have to go through the same headache as I did. Just thought this was odd considering how many times I have plugged and unplugged and never had any problems with adb.
Toggle USB Debugging....so simple. *rolleyes*
Same Issue
I've got the same issue on my EVO 4G. Just installed the latest CM7 and now it tell me device not recognized. If I manually install the drivers it gives me the same code 10. I can't bring up the phone as a storage device and toggling the debugging is not working. Any ideas?

You installed the hboot drivers correctly?
Boot into recovery, with usb debugging enabled, connect to pc, it should install the drivers.
Still the same
Even when I reboot into recovery it still gives me "USB Device not recognized." I previously had MikFroyo on my phone with no problems. I'm at a loss.

You most likely have a bad cable, do you have another one you can try?
Possibility
Not at the moment but that may explain it. Still seems weird for it to just go out right as I change to CM7, but still a possibility. I am going to run and grab my other cable. Thanks for the advice.
No Luck
The new USB cable didn't fix the problem. Also, in device manager, even with the driver installed its labeled as "unknown device."
If I boot into hboot the computer recognizes it.
**update: After rebooting from the hboot, my phone is recognized by the computer however, a disk drive is not coming up in "my computer." I have USB storage turned on but Im not getting anything.**
Any help would be much appreciated!
Sad Day
Apparently the Micro USB port on the bottom of my phone is going bad... I talked with some other people who've had the same problem. HTC knows that the ports aren't very sturdy as well. Well... sad day for me.
Also if you're getting the notice from windows saying that you your device will run faster in a 2.0 usb port and you know the port is 2.0 ... chances are your port is going bad as well.
*****UPDATE*****
Flashed to MikFroyo and none of the above stated problems. I would venture that it was CM7 but apparently everyone else is able to use it so who knows.
Dezire z keeps askinf for MTP drivee?? i recently flashed mexdroid rom, and in the beginning none of the usbs would connect my phone. I thought it was a nightly issue as it was based off of a nightly but now its using RC1.
Recently i played around, it wouldnt connect with the "ADB or Android phone driver." I fixed that and those work fine in Device Manager in Windows 7. However!, in device manager it KEEPS asking for MTP. i tried uninstalling, updating, everything!! and it just wont find my htc desire z.
ADB can find it when using command prompt. It can even logcat, and its weird why ADB can see it but windows cant. I have posted a Download link to the Logcat file. Im hoping anyone here can help me.

thanks
edit* i think i read somewhere Android doesnt use MTP drivers....-confused-
windows 7 can see my phone and lets me safely remove it too, but wont let me see it in my computer.
issues I was having with W7 x64 were resolved by PDANet. you might try it out, although your issue is slightly different than mine... the device was entirely unrecognizable (by adb, fastboot, the whole shebang).
edit: NOTE you don't need to actually use PDAnet, it will just locate an appropriate driver and install it for you, then you can uninstall it from your PC.. unless you want to use it, of course. pretty slick.

ive done this and it found the proper driver. "Android phone" BUT when it tries to connect with device, it says "failed to handshake with device" and proceeds to uninstall pdanet. Is it because its conflicting with windows 7 cant find the MTP driver?.... sooo confused.. never, ever had this problem
edit* after pdanet is uninstalled, the Android phone driver works fine, but MTP does not.

that's a bugger.
when you plug the phone in, in device manager, does it show as a USB mass storage device under the USB controller section? to check: unplug all usb devices (aside from input devices like keyboard/mouse/what-have-you). plug in your phone and go to device manager (right click my computer->manage->device manager). under USB controllers, check and see if there is a USB mass storage device. assuming you have disconnected any other storage media, this is your phone.
if it does:
uninstall this driver, unplug your phone, restart, plug your phone back in.
if it doesn't:
my next step (take it for what it's worth - I'm sure there's an easier way) would be to unplug all usb devices (including keyboard/mouse - anything USB related), uninstall EVERYTHING under the USB Controller submenu, then restart and plug the phone in.
W7 should automatically recognize and reinstall the USB host controllers and hubs.
edit: are you using any other USB storage devices? thumb drives, ext harddrives, etc? do they work?

Under the usb section in device manager, i have about 8 or so usb controllers and stuff. Im using a Gateway Laptop and only one thing is using a usb port--- the mouse. Thats all. So i dont really have a clue which one is my htc phone because when plugging it in and going into device manager the only devices i remember using the phone were adb, android phone, and Now MTP. If i could pinpoint which usb controller is using my phone ill uninstall it. Other than that, what else is there? This is the strangest problem ever

Have you tried the drivers from the official HTC Sync software? Also, are you actually trying to use the phone as an MTP device or as a USB mass storage device? I don't think you can use both at the same time (though I don't use this ROM so maybe things have changed). If you don't actually want the MTP functionality, I wouldn't worry about it.
Also, I noticed the notes for the ROM says "USB mounting is not working on a Windows OS computer" is a known issue. Not sure if that could be related...

windows 7 home doesnt have that script gpedit.msc
i looked all over google and it doesnt work . only pro and business versions have it.
Did the HTC Sync software not work? Also, have you tried formatting your SD card? Might be a long shot, but if it was ever used in MTP mode at one point, maybe your comp is detecting the files and thinking it's still an MTP device. Not sure if it works that way though...
Did you ever set the phone to MTP mode in the past? Like if you were ever on a Sense-based ROM. Maybe if you had it in MTP mode prior to flashing the new ROM, it stayed in it. Once again, no clue if it works that way since I've never used MTP on this phone before, but might be worth trying if you are out of options.
STILL havent fixed this MTP driver issue, have tried everything including the post above me!....NOTHING IS WORKING. why is it being recognised as mtp, when all i need is use the sd card.
this has been up for a week, seriously no one knows how to fix it?

I'm guessing it's because no one else has encountered this problem before...
So what happened when you flashed back to a Sense-based ROM? I've never used one, but I thought when you connect the phone via USB, you have to choose what kind of connection you want (e.g., HTC Sync connection vs Disk Drive). Are you saying even when you choose to connect as a drive, the phone still shows up only as an MTP device (which I'm assuming is what is used when in HTC Sync mode)?

i switched to MIUI rom where i can mount sd card, and it still shows up as MTP in device manager on windows. Its not a rom issue, its a issue with WINDOWS seeing my device as a MTP and not STorage ....stupid windows 7.

Well either Windows sees your phone as an MTP device or the phone is actually reporting itself as an MTP device (not sure how it works on phones, but typically Windows communicates with firmware on a USB device to determine its classifications).
I'm guessing you already tried this since it's one of the only threads on the G2 forum when I did a search for MTP...

anyone find any fix for this MTP ISSUE?
Hi all...bare with me here, I posted this earlier, but in the wrong forum section so I am going to start over here.....thanks for your patience....
Hi everyone...I have a problem..I tried to use the Firerat zips to increase my internal storage, and during the flash of the zip file the phone hung and I had to pull the battery out.....since then the usb wont mount.
I am using a Tmobile mytouch slide 3g.
I tried using the sdk and running the fastboot commands etc to get the sd card to mount...no go.
I have tried the fastboot oem enableqxdm 0 command and no go....
Note:..My sd card works fine in a card reader on my computer, I can drag and drop anything to it etc. etc.
Finally i downloaded the stock rom, and i was able to put it on the card, and rename it ESPRIMG.zip and installed it through recovery...My phone was rooted and S-off running ginger, but now back to stock...S-on, and hating the phone now...lol.....
I have been all over the web and I am so confused...everywhere you search there is something different, I just dont know what to do, Windows doesnt recognize the phone when plugged in so I cant load custom rom etc back on....AARGH!!!..I am so frustrated, and have a migraine messing with this damn thing.....lol...
Someone here suggested the MISC is bad and that a binary flash_img would fix it, but honestly, I have no idea what any of that means...all that means to me is confusion, and I have that already.....lol
Can someone please suggest what I may try doing?I am pretty savvy with computers but some of the adb/shell stuff is very confusing to me, I dont like cmd prompts...so maybe a detailed explanation?..
Thank you so much for taking your time to read my problem, I really appreciate it very much.....Dirtylarry
"Kharma...It's a good thing"
ok man im gonna try to understand the problem... you say your usb mount doesnt work but the sdcard works with the adapter, then you went back to stock and un-rooted and the pc doesnt recognize your phone? right?
So it looks to me (just an idea) that the problem is your cable or the port on your pc... just beacuse your sdcard IS working in your phone as well since you used the ESPRIMG.zip(wich was really unnecessary) and you flashed it using the sdcard obviously.
Now you need to find a way to root it again just like you did the first time... dont mess with the drivers since you havent changed them in your pc (i guess) and try this guide....
http://richard.gluga.com/2010/08/complete-guide-to-rooting-and-hacking.html
Now all i can say is ALWAYS DO A NANDROID BACKUP BEFORE MESSING WITH YOUR PHONE. And check the cable/ports... thats the only problem i can think of...
well the fact that I have 3 computers that all used to recoginize the phone just fine is what's weird....none of them do, nor does my usb connection on my car stereo...the computers all say "USb not recognized" etc. etc. and the car stereo says USB N/A .......So i'm just at a loss as to what is going on here....Any ideas????? Thanks much ....Dirtylarry
Try installing PDA Net. It installs USB Drivers and resets the registry. One day it would work, then the next day it didn't work, reinstalling PDA Net worked every time.
Thanks Wave_Sailor, I tried the pda net install but it wont work....Everytime I try it says that it can't handshake to the phone, and then gives me an error code 103, I have tried many many times....also, in the device manager for computer it shows a yellow Exclamation mark everytime I plug the phone in listed at "Other Devices", and says Qualcomm CDMA Technologies MSM....So I googled, and found another thread saying Install Windows mobile 6 center, so I did, and nothing changed.......ARGH....DIrtylarry
Do part III, but while the phone is unplugged, download and install HTC Sync, and then plug the phone back in.

Still a no go on the Mass storage device......hmmm.....so weird of a problem to have....I would have thought that clearing everything on the phone and going back to stock would have done the trick......any more ideas?...Thanks so much for your help.....Dirty
Have you checked in device manager on your computer to see if the mass storage device has a yellow triangle? I just went through the same thing but in reverse. My pc would see the sd card while in my phone but not through the reader. I still haven't gotten it straightened out either, just learned to live with it.

Make sure you don't have any drivers disabled. Ran into that problem with a different phone. I had one driver disabled so it wouldn't install some of the other drivers.

Ok...just checked,...no drivers disabled in device manager...has to be something wrong with phone...its a/most like the driver is missing from within the phone or something...isn't there some way to get this back to where I could root it and install a custom rom again without the USB to phone connectivity and use my card reader to get some sort of files back onto phone that way?
ok....well I re-did the whole flash process over, and I am now rooted again once more.....I dont know how or why or what...but I am now going strong again.....lol thanks for the help everyone,
Last night I was getting ready to do my first root. Was watching the syndicate video, following along.
One thing I noticed last night, is when I plugged the phone in for mass storage, to copy the files to the sd card, I kept getting these two errors.
First, when installing the drivers after plugging the phone in, I was getting this cdc failed. You can see it in this picture...
http://i11.photobucket.com/albums/a183/lardo5150/cdcabstract.jpg
I also kept getting this "scan to fix" pop up for the M drive (my phone).
When I turned on USB debugging on the phone and plugged it in, it seemed fine, except I could not access the M drive on my computer, I would get this error...
http://i11.photobucket.com/albums/a183/lardo5150/insertdisk.jpg
I did some search and decided to try what another user tried, I formatted the sd card.
I then plugged the phone back in, and did not receive the "scan to fix" errors anymore and could access the SD card with no issues, but I could not access it still while in debugging mode.
Is this by design?
Samsung drivers are installed. Got them straight from the samsung site.
No yiu should be able to play with your sd card wgile in debugging
Did you turn on mass storage after usb debugging?

I couldn't access the mass storage in USB debugging for a little while. It turned out my drivers got slightly corrupted. I could do everything else but that. Went into Control Panel with USB Debugging on and found the driver listed as samsung android in USB in Device Manager and hit update driver and let it get it from Windows Update.

How about that cdc? Any reason why that is failing?
Same thing.
Says the latest driver is installed.
It never gives me the option of choosing charging, mass storage, tethering like it does when debugging is off.
Any ideas?
Ok, so I found this some other forums.
Seems stupid, but I had no clue.
With my phone, with debugging off, when you connect the USB, it asks you what you want to do.
With debugging turned on, it does not, you have to tell it. Below is what I found....I feel dumb..
"Okay, so if you are freaking out, or can't figure out why your new Epic isn't being recognized by your computer, calm down. Some of you are probably already searching for drivers. Ya I already went through that freak out when I got my Vibrant. Okay, to mount your phone, and have your computer recognize the internal/external memory, do this:
Connect your phone to your computer via USB. Give it a few seconds.
Next, PULL DOWN your notification bar.
Next, tap your finger on "USB CONNECTED"
You then get a message asking if you would like to mount. Tap "mount" confirming you would like to do so.
Enjoy, your computer should now recognize the internal/external memory."

Also, I've had success with rebooting both the phone but especially rebooting the computer and plugging the phone back in. Try a different USB port, some folks have 2 SLOW USB ports for mouse and keyboard (mine are in the back lower left...the fast ones are on the right and in front). Most folks have better luck trying rear USB ports (although I don't know why). First, try the computer reboot though...
My computer won't detect my Epic 4g when it's powered up, with either Debugging enabled or disabled. BUT, it does detect it when the phone is in Download Mode.
I have tried several different cables on all my usb ports. And the cable and port that I am currently connected with works perfectly on my other Epic 4g...
I wanted to root this Epic, but couldn't get computer to recognize it. When I plug it in when phone is powered up, I get no notification in the sys tray, nothing new shows up in device manager, no new drives show in My Computer, Odin doesn't recognize any devices.
So I put phone into DL Mode, plugged it in, and the computer recognized it, installed drivers, and Odin installed both Kernal-GB-3a and ACSRecovery1.0.0.5 successfully!
But when I boot the phone back up in order to copy the Superuser zip file onto SD card, same problem as before... Whether I click "Connect storage to PC" on phone or not, computer doesn't acknowledge.
Any advice?

when you allow windows to automatically install the drivers, it doesn't always install the drivers properly. but when you manually install them, the installation process assures that they are ALL installed properly.
