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.

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

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.

Anyway to treat a USB connection as a disk drive instead of a "device"?

It seems that when I connect the phoen to the computer to transfer files, it'll recognize the phone as a device and in "My Computer" it'll show up as one, instead of a USB flash drive.
It's annoying because everytime I wan to transfer files over it'll ask to confirm. I can't see the transfer speed as well in this mode.

Enable USB debugging. Then it will ask to to enable mass storage after you plug it in.

Or go to Settings/ Wireless & Networks/ USB Utilities press the activate button BEFORE you plug in your USB cord. Once you activate the phone will tell you to plug it in.
Word of caution: Make sure you " safely remove the device" on your PC before you unplug. I borked an SD card not doing that.

For USB Storage mode:
1. Disconnect
2. Settings->Wireless and network->USB utilities
3. Click button: Connect storage to PC
4. Plug in USB Cable
I hope it helps.

Do you mean adb connection or usb mass storage one?
I don't know whether you've checked this yet, but try this:
if you mean the adb, on the home screen, press: menu>setting>applications>development>check on usb debugging
if it is usb storage, refer to what mayerkemp said
or if you can see usb logo on notification bar, slide it down and tap connect storage to pc

Thanks guys,
Problem is that when I click on connect storage it either says "connect the cable to use mass storage" or if the cable is connected it says "USB is connected. Remove the cable."
Any thoughts?

Hi guy's, so I've reinstalled a backed up rom and it's fine now.

Just always check development mode on application setting, then u can change to usb storage with tap usb connected from expanded status bar, that's what I do on DXLM3
Sorry for my bad english
