I need to send vendor-specific SCSI commands to a thumb drive. This is done with ioctl on Linux and SCSI pass-through on Windows. I researched this list and started with the VendorSpecificType00 example.

I changed the vendor properties in the plist file (see below) and I'm able to load the driver. I see it with kextstat.

When I insert the device I get the following error, though.

IOSCSIPeripheralDeviceNub: family specific matching fails
Matching service count = 0
IOSCSIPeripheralDeviceNub: match category IODefaultMatchCategory exists
Couldn't alloc class "com_wagerlabs_driver_SeaForth24"

What I am doing wrong? I'm a complete newbie at this, although I just came off a bout of assembler hacking (http://tinyco.de).

Help!!!

	Thanks, Joel
