HTC Desire won't mount as a drive?

Hi guys, I'm obviously new here, but I did have a look and couldn't seem to find this answer anywhere else.
I'm trying to hook my HTC Desire to my PC, but every time I connect it via USB cable it says that device drivers are not found and that Windows cannot rectify the problem.
I've tried installing HTC Sync, but the PC won't even recognise that there's a phone or mass storage device hooked up, so it just stays at "disconnected".
I've selected the phone to appear as a mass storage device when I plug it int the PC (I even select this on the phone's display as I connect it via USB so the phone realises that it's being plugged into a PC).
Does anyone know how to fix this?
Thanks in advance.

I've struggled with a problem like this before (though, a flash drive, not a phone).
There were two solutions that helped mi on two different occasions.
1) Removing all usb devices from the computer. Shut the computer down, take out the power cord and wait for 20-30 min to settle all capacitors. Then turn it on and plug the devices back in.
2) Put the device in the computer as Mass Storage. Go to device manager and see where is the device. Right click on it (should be unknown or stuff), choose update driver. If it doesn't find anything try updating windows with latest patches and try again.
3) I was solving a non-detectable usb webcam, but removing ALL usb devices from the device manager (Under USB choose device, delete, choose device, delete.) Then click Scan for changes on the top to refresh the devices and install the drivers of the usb root hubs, etc. This would probably fix the problem if the above fails.
---- edit ----
Quick note: if your keyboard/mouse are USB, you could hang without keyboard or mouse until you restart your computer, so keep in mind if you can detect them, delete them last
----/edit -----
If you still can't get it to work, please provide results from another computer (if it works there as mass storage), or better if you have some Linux Live CD you could try there if it gets recognised.

Where you try to plug usb cable into PC - front panel or rear? Because a lot of PCs have an issue with front panel usb. Try rear panel

Thanks to both of you for the swift replies
I actually figured I'd check this short fix before trying the more detailed ones and it seems like it was just a matter of plugging it into the rear usb!

I'm definitely putting this solution to my personal FAQ. Thanks, jankos.

HTC EVO won't mount as a drive
verified that issue was with the front USB port. I plugged my EvO in to a usb hub I had plugged into back usb port and it worked like it was supposed to.

[Q] USB connection problem.

another problem occurred.
I flash the 11.1 nightly on my defy,(As flunk03 said, wipe cache and dalvik before and after flashing), it works very well, but an USB problem comes out, when I plug the usb cable to microUSB port, nothing happened, the phone do not show the usb connection, the computer do not "ding", either. Then I reboot the phone, it connects to the computer and shows me charging.
PS, after flash the ninghtly, I uninstall the MOTOROLA PORTAL, does it relate with the problem? who can help?
thx in advanced.

So it's not the cable or ports, try go to Device Manager from ur computer and see if you can see any unrecognized device? If you do, just download the Motorola usb drivers and install it ...

thank you, but my pc do not react anything, and it happens randomly, reboot, then it is ok. i do not know why? and when i plug usb cable to the charger, the phone shows it is charging, so i think it is the ROM problem or something.

I have a similar problem with the MS2Ginger 2.0 Lite:
After selecting USB Mass-Storage Mode in the top menu the phone says "preparing SD card.." and then shows "MTP: no SD card found" or sth - but there's clearly a SD card in the device and it's accessible, too -> i can browse through the gallery and everything..
No Mass Storage for me it seems...anybody got a solution to this?

T989 USB Port DEAD

When I plug my handset to ANY computer (with, without kies or drivers, it doesn't matter) the phone charges, but, nothing appears on the computer (no unknown device or recognizing the two drives of the phone, but not mounting them (as it did before)) on the phone.
The "USB" icon doesn't prompt and if I go to settings/wireless and network/ USB utilities, when I touch the USB mass storage button, it prompts me to connect cable, which is already connected.
-USB debug isn't activated (I've tried both)
When my phone is powered off and I start to charge it, the charging screen doesn't prompts, It just start booting.
I've tried different USB Cables.
The Phone is Official Stock Never Rooted (I discovered this trying to root it today)
Am I SOL if I want to root it without a working USB Data port?
Any ideas?

i would say make sure there's no dust/ buildup in the port. I had connection issues once to find a pocket lint cramed in there. next do all the other stuff. uninstall/reinstall drivers, diff usb port, diff pc, reboot. My symptoms were similar to yours but i was able to reboot into recovery/bootloader and use adb/fastboot no prob, so not sure. and I was already rooted/twrp recovery. might be worth it to try fastboot in bootloader just to be sure and get a recovery on it asap. If that works you should be able to recover stock or flash whatever, then test usb again in diff pc with fresh kies install. good luck.

Sounds like bad/improper USB cables to me, not all USB cables support data and charging, make sure you're using an official Samsung USB cable.
If you have a friend with a Samsung smart phone ask to try their cable.

Phone only charges when connected to PC

As stated in the title, When I plug my phone into a computer, it only charges. The dropdown menu allowing you to select different options (MTP, only charge, etc) never appears.
Things I have tried :
- Cleaning out the USB charging port
- Multiple reboots (with airplane mode, without, with USB debugging on/off)
- Using different cables (2 of which I am sure can be used to transfer data as I've done it in the past)
- Different computers (My laptop has debian, desktop has windows 7. Also tried on a windows 10 computer)
- Updating firmware to 8.4.19 (recommended firmware for multiple ROMS)
- Dirty flashing to final Ressurection Remix release from a July nightly
- Searching google and crying
I would like to Format data and try another ROM, but without USB transfer and ADB sideload, my hands are kinda tied.
Anyone have any suggestions as to what I can try ? Part of me thinks its a software issue because the usb-c cables fit in so tightly and snug inside the port. In the mean time, I've ordered a new charging port from aliexpress. I'm hoping I don't have to open up my phone though.
Thank you for your suggestions !

Use an usb otg with a usb stick memory and see if your phone recognize it. I'm using otg to flash roms and firmware via TWRP.

Thank you for the suggestion. I don't have one, but I suppose if I can find a cheap one it's worth a shot !
I also just realised I can plug in the little dongle and listen to music through wired headphones... Strange !

Even if you are inside TWRP/fastboot mode the computers don't recognize it?

Nope, I can't see anything. It wasn't the case before, I used to transfer ROMS while twrp was loaded, no problem

So I just changed the physical piece (charging port) with a non-oem one, and nothing changed. Still charges, but won't connect to PC. I'm lost as to what I can now do

Tried OTG, I only get the "USB supplying power to attached device" notification. You reckon if I "hide" a rom in the / folder or some other top level folder, I can go ahead and format data and wipe everything. I wouldn't delete the Rom in the process ?

Put a rom on usb stick, reboot phone into TWRP, connect USB-OTG to the phone, get the stick into otg and go to install -> select storage -> usb otg (hit it) install the rom.
If your phone can detect the otg you should be able to install rom and firmware.

I tried that. It won't let me mount in TWRP. When i'm booted in the OS, only power is transfered through USB when I connect a usb key using the OTG dongle. No data. Oh well. Can't say I didn't try. At least the rom I'm using is good. I just wanted to upgrade to android 9.0 but it seems like that won't be happening.

Your problem seems simular to what I had.
If you are sure the software settings are ok and that doesnt work, remove the backcover remove the battery connector, put it back again and see if that works. Does charging work?

Thats weird my s2 tablet has USb problems to. It stopped reading OTG usb connections and the PC. However it is always able to charge. I have noticed that when it does finally read on the PC it seems like the drives dont switch right and my battery wont charge. It got to the point I dont even try to plug it into a pc or USB otg just incase it quits charging I have SD card and twrp for installs so I use that instead. Most be a problem with the usb port and drivers.

I dont know the answer nor the solution.
What I noticed however is that I used my tablet as an monitor for an USB web cam.
The problem (charging but not being able to connect to PC) started AFTER I removed the webcam.
The app I use (USB Camera Pro) has an option "remove camera safely"
If I use that option everything works fine but if I remove the cam cable without pressing this option I cant connect to my PC anymore and have to unplug the battery.

I am having a similar issue and would be grateful for help. My Tab T815 has a clean install of the latest Android 10 Rom and Pico Gapps via TWRP 3.4. All seem to be working great apart from the USB OTG. Specifically, I am trying to connect my DJI Mini drone controller and it's not registering it plugged in. I also have Android 10 on a galaxy S5 and have no issues at all when I connect the DJI controller to the phone. I have run a diagnostic app that says OTG is compatible with the T815 so am now at a loss on what to try next. Could this be an issue with the Rom?
