I get the message when i connect the x10 to the pc "usb device not recognized" i´ve tryed other cables and uninstalling the drivers and reinstalling them. Even anoher pc. but i get the same message where ever i try.
Is it possible that some of the pins are broken?
Is this something i can fixed on the warranty?
If so, even if i have installed a custom rom?

------

I turned the phone in and they replaced the SWAP-Unit. All on warenty! When i turned the phone in i asked the dude there about custom rom and repairs, he said it dident matter aslong as its something wrong with the hardware and not the software ofcaurse ;)

it says not recognized when i connect the phone to the pc even in flash mode, and the programs dont detect that its conneced.
Then you propably got broken usb connector or your IC controler on motherboard stopped working. If you look at your connector and all the pins just looks fine then connector is really ok. Now, it is surely IC controller. You have to send your phone on warranty, and you are going to receive a new one. Yes, a new phone. There is no other way to fix this. And from what I know, you don't have to bother about different ROM installed. No one else bothers bout it too.

edit:

Oh BTW, if this happened now, then propably in short time you will loose ability to charge your phone VIA USB connetected to PC, if not immedietly then after this charging won't be possible at all, even with AC charger.... So... be prepared.

No my connections looked fine but on metering from the USB connector to the filtering circuit it was open circuit I flowed solder on the joint I then had continuity reassembled and all worked great, no need to go to the interface circuitary. I am saying if the system cannot read the voltage drop across the shunt resistor it cannot control the current and will not charge.

first, try a different usb cable, I had the same problem. as for the mounting problem, should have made a new thread, but you should mount usb to transfer files, but no need to if just charging, but be sure to unmount or else you could corrupt your sd card, and it also creates another drive on your computer if you don't 'safely remove usb' after unmounting
