Hi,

Over a month later, here it is - this drivers/usb/storage/unusual_devs.h entry appears to be sufficient to make my Sagatek DCS-CF work:
/* aka Sagatek DCS-CF */ UNUSUAL_DEV( 0x07c4, 0xa400, 0x0000, 0xffff, "Datafab", "KECF-USB", US_SC_SCSI, US_PR_BULK, NULL, US_FL_FIX_INQUIRY ),
Not even US_FL_MODE_XLATE or US_FL_START_STOP is necessary as far as I can tell, but I guess that may depend on the chip revision. US_FL_FIX_INQUIRY is required, or the device does not work at all...
Boot messages (with a 64MB == ~61 MiB CF card) look like this:
scsi1 : SCSI emulation for USB Mass Storage devices Vendor: Datafab Model: KECF-USB Rev: 0113 Type: Direct-Access ANSI SCSI revision: 02 Attached scsi removable disk sda at scsi1, channel 0, id 0, lun 0 SCSI device sda: 125185 512-byte hdwr sectors (64 MB) sda: test WP failed, assume Write Enabled sda: sda1 WARNING: USB Mass Storage data integrity not assured USB Mass Storage device found at 2
The "test WP failed" message appears to be harmless - I have tested reading and writing, and it works for me.
