After connecting my N900 to PC the phone is not recognized by the PC. I used new micros USB cable bought on Ebay when this problem occurred (I doobt it is a coincidence). Before, with original cable it worked OK, now it's not working at all. Windows alerts with: "USB device not Recognized. One of the USB devices attached to this computer has malfunctioned and windows does not recognize it". The phone detects cable being pluged in and offers if I want mass storage or PC Suite mode, but it doesn't matter which one I choose. It also stopped charging from PC.
