New rom on phone - USB connection no longer works

I've successfully installed the Open Desire rom on my HTC Desire, but if I try to plug in my phone to my PC I get a windows noise (asif a USB device is connected), but no access to the actual device (e.g. the drive doesnt appear in my computer).
Any ideas on what to do? It was working fine on the same PC before installing a new rom...
Thanks.

USB brick?
Sent from my Evil Lair using Doomsday Device

Ok I tried plugging into a different PC (which it hasnt been connected to yet), it goes to install the phone USB drivers and then it comes up with "USB Device not Recognised" in windows XP...

Sounds like the usb brick as mentioned above.
What recovery method did you use? Is your phone seeing the sd card?

I had the same problem, can you install from Market? I fixed the problem by changing the default install location for the apps.

Now I can connect both discdrive mode and htc sync. Latest OTA did this for me.

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] PC wont recognize the phone in Device manager

HTC Sync manager and mobogenie also wont recognize the phone.
Checked with both USB debugging ON & OFF. No go.
Thanks in advance.

[Q] Laptop won't detect phone!

Laptop won't detect phone, tried different PCs, different USB cables, and even got the USB port changed but still no luck. When I connect it to my LED TV, the phone says it is connected in USB mode and disk drive option works. However, when connected to laptop, it goes only into charging mode. Downloaded the HTC Sync Manager too but still no detection of the phone whatsoever. Help, pls?

I tried on Windows XP, Windows 7, and Windows 8. The hardware manager says NOTHING, there is no notification when the phone is connected. Although today I tried it on Windows 8.1 pro, and it worked for like a minute. All options worked fine, the disk drive, USB Tethering etc but then it stopped working again.

I bought it off the internet a month back. The guy I got it from said he never rooted it. So, no custom rom or any modding done yet. I'm currently using Ubuntu, this too doesnt detect my phone. And I tried again on my LED TV but the USB Connection was established in like 2 seconds so there's no problem with the port or the cable. What drivers do you use? My phone doesnt even get detected by the HTC Sync.

Oneplus 3 does not connect to pc

my oneplus 3 does not connect to my pc. I have tried turning on and off developer options, turn off and on oem unlocking and usb debugging. I change the usb connection to mtp from charging but does not change. Also does not recognize it when i connect to pc. Also does not pop up on status bar and i checked portable devices. I also tried installing the oneplus drivers. i am on Android 7.0 freedomos-2.5. Any way to fix this issue? i might try to update freedomos because im on a old version of it.:crying:

Windows? If, yes windows drivers are the problem.
Try to other pc, to see if it works., first.

I have tried it on both my PC and laptop with both windows 10. Does not work. My PC also has windows 7 still seems to not work. Are there any other drivers i might be missing?

i have also done some research that you should update your drivers from device manager. I dont see anything related to my device. i went to portable devices nothing and i dont have a other devices section in device manager. Any help?

What recovery?
Try to flash latest twrp. I use blu-spark by eng-stk. You can fla**** thru recovery or Flashify app.

ive also found out theres no kedcom driver when i go to fastboot. i even reinstalled adb drivers to insure its there but it does not pop up.

You'll need to remove drivers reboot, install correct drivers, reboot and then be nice to everyone you ever meet and it'll show up. It's a real pain but you can get there. XDA tutorial all the way there!

I once have kind of youre problem connecting to my laptop (win.10). But, at work, on that laptop, connection was ok (win.7).
I reinstal windows 10 and connection works fine, since.
I allways use latest TWRP & version of rom. I can't tell for sure what it's goin on with youre phone.
If i was in youre situation i format my phone (this will erase ALL in youre phone). And if PC still does not see the phone reinstall windows.

Also: Try a different cable.
A cheap cable could have a charging pin layout but lack data pins connections.
9 out of 10 issues with connecting to PC and getting odd behaviours is due to a bad/wrong cable.

Driver issues win 10
Find the excellent tutorial here on drivers.
For some reason my phone didn't show up but was able to receive commands. It was frustrating because I wanted to use the all in one XDA product but couldn't.
Even if you installed drivers they can be broken!
Do drivers from scratch per xda tutorial. Don't forget reboot!
Try different cables and usb ports! My front ones never seem to work!
Don't just try fastboot commands also try adb. Like I said mine wasn't seen properly yet it took the commands.
Unless your windows is a years old install it shouldn't require reinstall.
Factory phone reset might help.
Best of luck!
