 Q: How do I get my BFL/Icarus/Lancelot/Cairnsmore device to auto-recognise?
 A: On Linux, if the /dev/ttyUSB* devices don't automatically appear, the only
 thing that needs to be done is to load the driver for them:
-BFL: sudo modprobe ftdi_sio vendor=0x0403 product=0x6014
-Icarus: sudo modprobe pl2303 vendor=0x067b product=0x230
-Lancelot: sudo modprobe ftdi_sio vendor=0x0403 product=0x6001
-Cairnsmore: sudo modprobe ftdi_sio product=0x8350 vendor=0x0403
-On windows you must install the pl2303 or ftdi driver required for the device
