htc keeps asking for MTP driver?

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...

[Q] after installing android SDK and rooting Nexus File transfer stops working

I've never had a problem with android file transfer up till I rooted today. My wife has a stock Nexus 7 and I can plug her Nexus into my computer and the file transfer app will start. I have usb debugging turned on and the usb connection on my tablet is set to Media device.
Now as I'm typing this my Nexus has been connect to my mac for about an hour. I just went to the USB settings to make sure I had Media device selected and the file transfer window popped up out of nowhere. I killed it and tried again and it won't come up. Maybe in an hour or so if it does the same thing.
Any ideas as to what's going on? Very strange behavior.

Disable USB debugging.
Unplug/plug in your nexus.
The USB IDs change for some reason when you have USB debugging turned on and the MTP device isn't recognized as such. PTP (camera) mode continues to work for both cases though.

Thanks for the suggestion but It still fails. I disabled debugging and still can't connect. Switching USB modes didn't help either.

If that doesn't work uninstall the adb driver & then plug your tablet back in so it will reinstall

My next suggestion would to reboot the tablet with USB debugging turned off.
If that doesn't work, my next suggestion would be to delete the existing drivers and force reinstall.
All with USB debugging turned off.

Make sure after you plug in your device you're looking at your tab and click OK on the pop up........

Thanks for all the suggestions. It's working now. I was just about ready to delete the driver and the tablet started to be recognized consistently. I was in the settings screen and toggled debugging on and off while plugging in the tablet. I noticed the info bar at the top alternating between showing "debugging" and "media device" and I selected each one a couple of times when they came up. I think that it finally worked through the ID confusion that was mentions. I'll follow the the rest of the instructions if the problem comes back.
Thanks again.

It's acting up again so I'm going to try deleting the drivers. I thought I knew what to do but I can't find any information. What's the procedure to delete the driver? I'm running os x lion

I've tried every suggestion in all of these threads so far & nothing worked. Even after I deleted the ADB drivers, windows 7 would automatically reinstall them. When I tried to update the drivers, win7 said they already had the best drivers (ADB).
Here's what worked for me:
I had to turn off USB debugging, delete the ADB drivers in Device Manager, then reboot the device while it's still plugged in. Windows recognized the device as an MTP device & installed the drivers before it even fully booted.

I'm not sure how I finally resolved the problem on my mac. I toggled debugging on and off and rebooted a couple of times. That may have done it. I also ran the adb script in the SDK platform-tools folder. I don't know what that script does exactly but possibly it reinitialized the driver and ID.
Anyway, hopefully these workflows will work for others.

Rooted my nexus 7 (2012) last night and struggling with my laptop not recognizing it. This thread solved it!
Delete the ADB on my window, toggle off debugging and restart the nexus 7 with usb connected to laptop. works like a charm.
Thank you!

Guys, my N4 got this problem too.. until just a few minute ago
I read somewhere ini goge groups (i think N5 group), and found explanation that we can change ADB or MTP "mode" on device manager. On "Androoid ADB Device" right click and select "Update Driver Software". Click "Browse My Computer for Driver Software" and then "Let me pick from blablabla...." And then select MTP USB Device, "next" and my N4 detected on Windows Explorer.
Hope it will be usefull for you guys.

PC won't recognize internal memory

OK so i did the wugs toolkit for the n7 2nd generation but I think when it tells you to take out all drivers of any nexus device I think I took out to many because now after rooting it and it works fine so does adb and I have that installed I connect my n7 to my PC running windows 7 and I can't recognize the internal memory when it shows up in a little window And you open up the folder and such and it says internal memory it doesn't even say that please help was working not it forever also I thought because I didn't have device connected as a media device checked I thought that was the problem but the window for the option to open up the internal memory to move ROM files and such still doesn't show hopefully you guys can help me out please also sorry if you can barely understand.
PLEASE HELP

Have you tried disabling USB debugging and enabling MTP mode?
You can also try the MTP driver inf here:
[FIX] MTP with USB debugging / ADB within Recovery (windows/nexus7)
You can also try using USB Deview to uninstall the drivers and have everything reinstall. Sometimes that kicks everything into gear. Just sort by creation date and uninstall everything that says Nexus 7 in the last few days.

Hello gentlemen,
i got the tablet for three days and all was fine.
Yesterday i installed unofficial CM 10.2 build and since then when i connect tablet to PC,
my tablet is detected as Nexus 7 with exclamation or as deb also with exclamation,
I tried to install nexus 7 usb driver, but it didnt find any device to which it could install the driver.
USB Debugging is enabled, if i disable it, nothing is detected.
What are my options now? can it be solved?
Everything else is fine.

No you aren't screwed, you really got to want it to break it. Just so I am clear then it won't show up as an external hard drive or anything unless you do a peer to peer setup? Also are you running the newest nightly of CM?
"I had to turn off USB debugging, delete the ADB drivers in Device Manager, then reboot the device while it’s still plugged in. Windows recognized the device as an MTP device & installed the drivers before it even fully booted."
Found this well reading on it not connecting to the pc. Simple enough to try out.

Yes sir, I can only see it as PTP or MTP, nothing else.

Should MTP be enabled when rebooting the device?
What i should achieve by doing this?
EDIT.: after restart of device it's trying to install AOSP on deb, unsuccessfully.

i thought that MTP is the only option to connect it to the pc because its sdcard is emulated on the same partition? my galaxy nexus and nexus 7 can only do MTP too, unless in recovery where i mount it somewhere along the lines of mount as usb storage?

You could be right, i don't know, i copied custom rom immediately after i got nexus, so i didn't really watched how PC see the tablet.
Anyway i successfully flashed back original firmware 4.3.1 and after reboot suddenly Nexus 7 is recognized correctly
and it automatically install driver from folder where i got usb driver from google. So .. i will take a few days pause before i flash custom rom again
Thank you all for helping me in this.

[Q] Rooted Nexus 7 Unique MTP Issues

Ok so I have a rooted nexus 7 that won't show up as an mtp device ever since I rooted another nexus 7 on the same computer. I have uninstalled all the drivers and re installed them a million times with device manager and USBDview nothing works. It connects to other computers as an mtp device, however ever since I rooted the other nexus 7 on the same computer it won't work. Also I don't have access to the other nexus because it was my friends. Obviously it's a computer issue because it connects to other computers as an mtp. I'm really out of things to try as I have searched for this problem, but only found people saying to re install the drivers. I would really appreciate some help because I don't know what to do. Thanks.

I also have weird issues. What I usually do is make sure the Nexus is configured for only one connection. So for MTP mounting I have PTP unchecked and USB debugging unchecked. Then I plug into the computer.
If it doesn't mount as MTP, I find it's usually because Windows has attempted to connect via ADB drivers. So I go into Device Manager and uninstall the device under "Android" while checking the box to remove drivers for the device. Then I unplug the Nexus and plug it back in, and it uses MTP drivers. I've always struggle with these driver issues for the Nexus, i don't know why it's so difficult. Good luck!

When I had issues with my mtp I had to uninstall adb drivers then plug my device back in so it would use mass storage and install the drivers. Somehow I have adb and mass storage working now with USB debugging on.
Check in device manager when you have adb uninstalled and see what your device comes up as.

I uninstall the adb drivers but for some reason windows automatically installs them right back instead of mtp drivers and then if I go to update drivers and select mtp as an option it says it won't work

When I try to install the mtp drivers it says "Windows found driver software for your device but encountered an error while trying to install it...your device can't start" Then it automatically installs the adb drivers. What would be the reason it won't let me install the mtp usb drivers? Has anyone else encountered this?
