hey guys,
just FYI, i had a similar problem but its working fine now.
just wanted to post here, maybe it helps some of you
USB stopped working entirely on my Desire HD, when connecting to ANY PC the phone charged but nothing popped up on the PC, OR the DHD for that matter.
- no USB logo in the Android tray on my Desire HD!
- no USB logo in the Windows tray on any PC i tried
- no USB mode query in Android on how to connect to the PC (disk drive, charge, etc) on my Desire HD, even though the "ask me" how to connect was checked
- no USB mode option when drawing the Android task bar down either
- no USB query in Windows on how to browse my Desire HD
- the PC would see a disk drive connected to it, but it was transparent (hidden disk drive?) and when clicking on it windows couldnt access/find a drive
this really scared me, i tried many cables and PCs and thought the USB port on my phone might be busted... but guess what, this is all it took to fix it:
reboot the phone... 0_o
hope this helps somebody...
