>Description:
PNY brand USB flash readers, both compactflash and smartmedia do not
work correctly. These do not seem to have a specific part or model
number. The UPC codes are 5149221159 (SM) and 514922115 (CF).
The cause is the same thing that apparently affects a lot of other USB
flash readers: these need 10-byte read commands rather than 6-byte.
Adding these to the quirks table in scsi_da.c seems to fix the
problem.
>How-To-Repeat:
Install one of these and do I/O. All calls succeed, but it appears that
you always read or write the first two sectors on the device.
