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...

missing usb connect modes...

i feel like i'm missing something obvious here, but i don't see pc software or charge only in usb connect menu anymore, also the menu doesn't come up when i plug in usb, i just get a prompt if i want to mound sd card or not, it used to have a menu with 5 options now it has 3 and i have to go into settings > storage > menu button > usb connection mode just to see the menu.
thanks in advance for any help on this.

K so i've been reading more on this and i see that google took charge only mode out of android.... is this correct? if so did they also take pc software mode out to prevent connection from pc running terminal?

is there any other way to use adb shell from terminal on my pc using usb connection than pc software mode?

I have no problem using adb with whatever default setting the usb connection is set to in CM10. Just make sure you have Developer Options turned on and Android debugging enabled.

k good to know thanks

Sorry to bring back this thread but I wasn't sure if you figured it out or not?
Anyways, try this:
In CM10.1, I select Mass Storage. Afterward, a screen pops up saying "Press to toggle Mass Storage". When it's not toggled on, that is PC Mode. When toggled on, it's Mass Storage

i figured out that its cyanogenmod that has missing modes when i changed back to a stock based ics they all came back. i have 6 or 7 modes in stock ics and i only had 3 in cm10

Yeah that's what I'm saying. I don't think they actually are missing. I believe they've combined the settings so it's easier to switch between pc and mass storage (one button toggle between the two).

yes i know they are combined i dont like it.

[Q] ADB works, but no MTP/PTP functionality

So I got my Nexus 7 2013 to work perfectly on my laptop, which runs Windows 7 x64. However, on my desktop, which also runs Win7 x64, I only have the ADB working correctly for the N7. As I recall, sometimes there is a device under Device Manager called "D:/", which is non-descriptive, but seems like the closest thing to the N7. I have tried to update this mysterious device's drivers by pointing to Google's USB drivers and the OEM drivers, but neither was accepted. There are also no devices with missing drivers listed in Device Manager.
At this point, I am not sure how to proceed. Is there a precise way identify under what device name/category the N7 shows up in Device Manager? Please advise. :fingers-crossed:

See if this helps:

Make sure USB Debugging is disabled, device is plugged in, and go to device manager in windows. Then right click on nexus 7 or android adb device, or any similar name. Then after uninstalling everything, unplug device and replug it in. Let windows get the drivers, and MTP should work!

Deleted everything related to google and nexus. Still installs as adb device but doesnt show as nexus 7 device! Wug fresh has this program in its tool kit

It might sound dumb, but I was literally just having this issue. But apparently certan roms or kernel disable MTP mode when they are installed. i reinstall every driver just now. My fix was as easy as going to Settings > Storage > Menu Button Top right > Enable MTP box.

Going to try a custom rom see if that works!

I have tried a number of the suggestions in this thread, including the deletion of all my google/adb/nexus (and samsung) drivers. None of these steps resolved my problem. However, at the end of the day, I can still use both ADB and MTP, just not at the same time. So it's not a big deal. I think I will mess around with Tasker and/or get a widget for turning ADB on/off.

Are you ale to get a nexus 7 device to show so you can access internal storage? I can only access camera storage.

Are you running stock?
If so, do you have USB debugging turned on?
If you have USB debugging turned on, the USB IDs change and it might not (depending on what you have previously installed) recognize the MTP device anymore.
If you turn off USB debugging, it should recognize MTP.
Now if you are on a custom ROM, there might be some issues on the ROM side causing the MTP problem. Try going back to stock and see if it works.
If you are on stock and have the case where MTP only works with USB debugging disabled, then you can try this driver inf I put together to address that.

[Q] MTP, PTP, HiSuite, MassStorage

Hi to all,
everytime I connect my Ascend P6 (b125, no ROOT, no MODS) to PC, it connect as USB MassStorage. (then I can not see in menu applications, that are installed or moved on SDCard). I can change connection type, when I pull down status bar. But I want always connect as MTP. Is there a way to set default connection type to MTP? Before I had Samsung with cyanogenmod, and there it was in Settings -> Networks and connections -> USB (or so something, dont remember...)
thanks.

I had the same issue, but not always, when my phone was connected to my pc

When you connect your phone and change the connection from USB storage to MTP, there should be an option right at the bottom, that says "Always prompt something-something", and untick that.

This does require to modify boot.img which is a tricky operation.

I have a similar problem. When i plug in my Huawei Ascend p6, nothing happens it just starts charging. It use to open a window where it asked me what type of connection i would like to use, i probably selected charge only for default, and now i dont know how to change it back. Pls help.

yes, tried that. tried different USB cables, installing/reinstalling usb drivers. I copy shows and things to my tablet to watch and It used to work, but it hasnt in some time and it kinda sucks having to power off tablet and pull sd card out to copy to it. Just getting frustrated with it. I even reset the device and updated it to android 5

Running through options, sounds like the computer. Can you hook up your phone?

Yea, phone shows up ok and just for the hell of it plugged tablet into laptop and it came up fine so i guess i have to figure out what is wrong with my desktop
