Tomas Kopsa deacon at volny.czHello Weicai, Yes, I'm using this cable (with Prolific Technology converter). You can check your USB cable info with 'lsusb' command (see my last e-mail). The most important thing is the voltage of the cable output - cannot exceed 3.3V else you fry your phone !! (see http://bb.osmocom.org/trac/wiki/CalypsoSerialCable). If you want to make 100% sure about the voltage, you can measure that with every DC voltmeter. Tomas > Hello Tomas, > > Does common USB->2.5 jack work?
