machines with USB interfaces and a Panasonic USB FDD
>Description:
Panasonic USB FDD "MATSHITA FDD CF-VFDU03" does not work.
The FDD is detected, but when trying to read or write,
errors occur.
In dmesg:
umass0: MATSHITA CF-VFDU03 , rev 1.00/0.00, addr 2
da0 at umass-sim32 bus 0 target 0 lun 0
da0: <MATSHITA FDD CF-VFDU03 1026> Removable Direct Access SCSI-0 device
da0: 20KB/s transfers
da0: 1MB (2880 512 byte sectors: 2H 18S/T 80C)
but, when I executed "dd if=/dev/da0 of=/dev/null",
umass0: Unsupported UFI command 0x08, 6 byte command should have been converted
da0: reading primary partition table: error reading fsbn 0
umass0: Unsupported UFI command 0x35
(da0:umass-sim32:0:0:0): Synchronize cache failed, status == 0x6, scsi status == 0x0
>How-To-Repeat:
as described in "Description:"
>Fix:
I think that the auto detection of UFI based drives in CAM is the best,
but I don't know the CAM architecture well.
So I wrote a patch similar to the quirks for YE-DATA USB FDD Drives.
