OK - "test WP failed" is harmless (unless there are read-only CF
cards...), but it would still be nice to track down that bug as it
might affect other devices (those that require MODE_XLATE).

In the meantime, may I ask you nicely to add this to 2.4.20
drivers/usb/storage/unusual_devs.h ?

/* Datafab KECF-USB / Sagatek DCS-CF (Datafab DF-UG-07 chip).
 * Submitted by Marek Michalkiewicz <>.
 * Needed for FIX_INQUIRY. Only revision 1.13 tested.

UNUSUAL_DEV( 0x07c4, 0xa400, 0x0000, 0xffff,
                US_SC_SCSI, US_PR_BULK, NULL,
                US_FL_FIX_INQUIRY ),

Note that this uses the normal US_PR_BULK protocol (not US_PR_DATAFAB -
tried that one too, didn't work) so this shouldn't be conditional on
CONFIG_USB_STORAGE_DATAFAB, just always included. It seems that newer
Datafab devices are slightly less broken^Wunusual than the old ones ;)

I say "Datafab" because the name "Sagatek" (
appears only on the packaging. There is a Datafab chip inside, and
"KECF-USBG" is actually printed on the PCB inside...
