The generic scsi documentation says group 6 (device-specific)
commands, with operation code 0xC0, must be 12-byte commands. When I
'write" an sg struct containing a 12-byte 0xC0 command, it returns
okay, but when I 'write' on sg struct containing a 6-byte 0xC0
command, it returns a -1 return code. My problem is that the device I
am controlling is designed for 6-byte 0xC0 commands. What can I do to
pass the 6-byte commands through to the device? I am using an Adaptec
1480 pcmcia card with the aic7xxx driver.
Thanks.
