A friend of mine has a weird problem with his usb device. He asked me to repair it, but it seems there is no way. I have tried some programs on internet but they where for other manufacturers. The usb is not recognized and it doesn't even show on the device manager. It only shows a device which has 0 bytes! The device model is this one: http://compare.ebay.com/like/250934751591?var=lv<yp=AllFixedPriceItemTypes&var=sbar&_lwgsi=y&cbt=y Any help?
