The protocol definition also lists error code 15 as "Others".

So, the hokuyo worked fine and now suddenly doesn't anymore after you power cycled the Hokuyo and rebooted the system it's running on? You can also try another computer to be safe.

But, in that case I think there is a problem with the hokuyo itself. You can try checking that the power is OK and data connection is worked. Also see if the output of dmesg shows any errors when you plug it in.

As a minimal test on the software site you can try connection with a terminal program to the device (e.g. gtkterm) and send the V command (basically V<enter>). The hokuyo should reply with version information.
