Thanks Neil. I've just tried my micro-USB cable, and it fits. Windows XP didn't detect anything and there's nothing displayed on the unit - it doesn't even charge. The manual simply says "Reserved USB Hot [sic]" lsusb shows it as "Microsoft". From memory 045e:ffff. dmesg just says it can't access the device. I'll do a c&p once I'm back on a Linux machine. May try to upgrade to 9.10 to see if that helps. T
