I am currently writing a driver for the Artec AT12 scanner. Everything
works fine if I don't get a check condition status. If I do get a check
condition status the scanner hangs the bus and the only way to continue is
to turn off the scanner. As far as I can tell this is a bug in the scanner
firmware, it wants to return 28 bytes but Linux asks for only 16 bytes.
Now comes the question, can I turn off the automatic request sense so
I can give the request sense command myself and ask for the 28 bytes ?
This should only be nessecary for the test unit ready command, so if
I can only give a test unit ready command without an automatic request
sense the problem should be solved as well.
TIA, Mark.
