Lol after trying so many drivers and it being the generic driver makes me angry. Here's what I did.
1. Right click on My Computer, go to Properties.
2. Go to Device Manager
3. Find your My HTC (should be the second one Android USB Device), right click on it and select Update Driver Software
4. Then select Browse My Computer for Software
5. Then choose Let Me Pick which driver to install on the bottom.
6. Then choose USB Mass Storage Device
Then it takes some time to think and viola! All working! However we are not DONE!
EDIT: So the next step I did after experienced issues remounting after unplugging the phone. I have change the MTP to ADB Testing Interface and things seem to be mounting everytime. Rebooted phone and PC, both worked again so I think this may be a working solution.
Now go to MTP.
1. Right click on My Computer, go to Properties.
2. Go to Device Manager
3. Find your MTP (should be under Unknown Devices), right click on it and select Update Driver Software
4. Then select Browse My Computer for Software
5. Then choose Let Me Pick which driver to install on the bottom.
6. Then choose Google Inc. and the Driver is ADB Testing Interface.
ENJOY!

Thanks ALOT
This definitely work I was gonna blow up my Windows computer, but this saved it... lol

I did something similar to that cuz I couldn't find some of the stuff when I choose "let me pick." But at the end I have two drivers under Android Phone that says the exact same thing in device manager and everything works!

Sorry but what is MTP?
I don't have Google Inc in my list?

I have both Mytouch4g and MTP listed in Other in device manager.
I also don't have Google Inc in my list? Can someone tell me how to get Google Inc in the list?

I'm on XP and I show two devices labeled Android ADB Interface. When I go to properties, the location for one of them shows LOCATION 0 and the location for the other shows LOCATION 0 (myTouch 4G).
Which one do I want to uninstall/change drivers for?
Btw my computer detected the device just fine on it's own and adb works but mass storage doesn't. Maybe I should just leave well enough alone?

Try the mtp steps first guys. That worked for me. Also, before doing the mtp steps I only had to go to adb interface then select Google Inc then adb interface again. Netbook with win7. Wtf is starter? Lmfao

I dont have xp i have windows 7. it took me a couple of tries but i just kept uninstalling and reconnecting the phone so that the devices show again. for the htc driver I pick mass storage just like he said after update driver. For MTP i had to pick android phone and then pick adb usb driver and it worked. I didnt want the mytouch one just sitting there without it working so i searched for a driver for that and picked the htc driver for that.. it all works!! thanks option94

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.
http://dl.dropbox.com/u/21509455/logcat.txt
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).

[Q] Mounting One X as disk-drive

Hi
I recently got the office Jelly Bean update for my One X, but I have one unsolved question.
When I plug my One X into my PC I can't get the internal storage to show up, neither get a menu on the phone to select which mode I want to use. I have managed to get it working in Ubuntu by enabling USB-debugging under developer tools, but neither my Windows 7 laptop or my Mac will do this. They just mount a CD-drive and the only thing I can do is to install HTC Sync Manager. This is frustating as I use a Windows Server to store photos and videos from my phone. The server operatingsystem wont install Sync Manager, and honestly I don't want to install some software I don't need.
How do I get the disk-drive functionallity back in Jelly Bean?

I don't think you can, I use WiFi file transfer pro to exchange stuff on my phone/pc

I understand what you mean by not wanting to install software not needed. Maybe this will be the solution to your problem. I the "[ROOT] One Click HTC One X (AT&T/Rogers/Others) (Win/Mac/Linux)" here on XDA I found a link to the driver only. Maybe this can help you... :fingers-crossed:

I tried using the drivers from the link, but unfortunately they didn't work.

If your phone is rooted you can do it via CWM.

Airdroid uses wireless connection. My computers don't have wireless access.

The JB update enables MTP and disables USB Mass Storage. It should show up in My Computer under 'Media Devices' or something like that. You can view all the contents of the internal memory there. This is the way it is on Galaxy Nexus, Nexus 4 and other devices.
MTP compatibility is flaky on Linux and OSX but is built into Windows 7 and works fine. The One X with JB should behave just as described. If its not showing in My Computer at all then something is messed up. Maybe a factory restore will fix it.

You're absolutely right. I got he JB update yesterday and i had the same issue. As it turns out, there are 2 links in Windows 7 in "Computer". One is to install the software but the second one talks about portable devices. Go in there and you will find an option for Internal Storage. It looks like an imitation of Apple iPod where you access the drive that way... Anyway, thanks for the solution.

or you can boot into recovery & mount usb storage from there thats how i do it with TWRP recovery

I eventually got my MTP drivers to force-install correctly by changing the USB network mode to Internet Pass-through. This was the only way that Windows would forcefully look for drivers and HTC Sync manager finally recognised it after this.

[Q] Unable to connect M9 to Windows PC

Got a weird one - got the M9, able to connect it at work and on a laptop but not the computer I've got ADB and everything on.
Phone simply does not recognize as a USB drive, I get that it's looking for "Android phone" but it never shows as a device. (MTP, ADB, etc) Suggesting where the HTC drivers I just downloaded results in me getting that they're not what it's looking for.
This is a computer that has worked for my EVO 4G, 3D, 4G LTE, One m7, m8 along with being fine with a host of other devices.
I've uninstalled and reinstalled everything I know to do but no ADB, no MTP. Not a recognizable device to windows other than being "Android Phone" with no drivers findable.
Some things I've done:
Installed HTC Sync
Deleted HTC Sync
installed HTC drivers pack
removed
Bang head on keyboard
Plug into different USB ports
Change cable
Just one computer, the one that I've used with no problem for ages, wants to be a punk

Have you tried enabling USB debugging?

-software information

-tap build number 7 times
Then go back to settings and enter developer options and check USB debugging

Yup. I just get "Android Phone" as an unrecognized device. I've also set to Disk Drive, MTP, debugging on and off.
Just plugged in the M8, same issue... so it's something that's not M9 specific...

Was this resolved? Having this same issue...

It looks like you are just trying to get ADB?
* Make sure USB debugging is enabled (I know you said it is).
* Make sure your computer is not blacklisted on your phone from making connections to ADB.
* Make sure any htc sync or driver package is totally removed.
* Make sure your keyboard still works enough after the head banging. You will only need a mouse, enter, space, a, b, c, d, e, i, s and v to complete the following; but more is always better just in case you need an h or something.
Look in Device Manager. Is it an unknown device (is there a yellow exclamation mark or something next to it)?
Try deleting the driver that it's using - like actually choose to delete the driver software from your machine, not just remove the device.
Once you're totally clean and the phone shows up with a yellow !, try update driver -> let me choose -> have disk -> your android sdk's extras/google-usb-driver .inf.
Pick one of the ADB ones, not sure if it'll be composite or the other one, then test with
Code:
adb devices
in your cmd window.
If it shows up, cool. If not try the other ADB usb driver from the inf...

Thanks. I tried this and nothing helped. Finding the device from ADB devices isn't the issue. It is that the SD card does not show up in Windows Explorer. Other than taking the SD card out and using a micro SD card adapter for my PC, I cannot transfer files via USB. See attached image. The MTP is the issue. Why doesn't HTC Sync/Drivers from HTC.com fix this? -_-;

Oh, I'm sorry I misunderstood your need. Well if adb works yes can always push/pull... Which version of Windows are you on? Is it possibly a 32/64 bit driver issue? I'm reaching here, HTC sync should cure whatever ails you... I hate MTP.

I' having the same issue. M9 not recognized as an MTP device on Win 10 64 bit. Running CM 12.1. Adb works, and the device shows up in Device Manager as "MTP USB Device" under "Portable Devices" section. Right clicking gives only propertied and scan for h/w change option, there is no option to update device driver. Phone shows up as HTC M9 under "Unspecified" category in "Devices and Printers".
My Lg G2 runs CM12.1 as well and works fine as mtp device. (Adb works too). I have been trying everything to get M9 working, but failed.
EDIT
Solved the issue trying random things! The issue was the xposed module "Xposed Media Scanner Optimizer" which was preventing MTP mode by not allowing media scanner to run.

I do not have that module installed, so that can't be what is keeping Windows from noticing my phone as a storage device.
Also, if i hadn't mentioned it before, I am able to see my device with adb devices in the command prompt.

Most likely it is a driver conflict or missing drivers. Uninstall all portable device drivers and start again.

Something to try. Connect your phone to the PC, then go into device manager and look for portable devices. The phone should be listed there and most likely you will see a yellow triangle on it. Click on it and choose to uninstall. After it uninstalls, unplug the phone from the PC and then plug it back in. Allow it to fully re-install before doing anything.

Nope. I've played with device manager for over an hour at a time. Windows doesn't like m9.

Well, my understanding is that the driver used for mtp for Android devices is the same driver that is used for Windows Media Player. When you connect your phone to the PC and open Windows Media Player, is the phone listed there? If not, then you may have something interfering with media scanner. Have you tried starting the M9 in safe mode and then connecting to the PC?

Weird. You must bring it to store to fix

Problem with connecting to my PC

Hello, everything was working fine, i always use my phone as a flash disk (i mean im not using HTC Sync Manager, but i just copy things to my phone like it was a flash disk) suddenly yesterday my phone was detected (the sound when i connect it) but instead of Storage there is just a "CD-ROM (F HTC Sync Manager" and in my Device manager there is the MTP thing with triangle and error 28 (file not found or something like that).

This isn't a worthwhile statement, unless you actually state what those things actually were. Otherwise, we can only waste our time guessing what you did or did not try.
In Windows Device Manager, select the option to update the drivers, manually select the drivers, and pick the generic "Android MTP" drivers (or some similar name). I often have to do this for my PC to properly "pick up" my phone's internal storage.
