Fixed two small bugs Ian Abbott pointed out. Ian Wrote:
The first one is just a tiny mistake in usbduxfast_ai_cmdtest():

	/* step 3: make sure arguments are trivially compatible */

	if(cmd->start_arg == TRIG_NOW && cmd->start_arg != 0)

should be:

	if(cmd->start_src == TRIG_NOW && cmd->start_arg != 0)

The other one is a mismatch between cmdtest and cmd.  cmdtest checks
start_src==TRIG_NOW or start_src==TRIG_EXT, but cmd checks
start_src==TRIG_NOW and otherwise assumes start_src==TRIG_INT.
