Thank you.

I'm afraid I can't easily help you because your device is different than
mine.

You can try attached patch anyways. Apply with 'cd /sys/dev/usb;patch <
jmtek.diff;cd /sys/modules/umass;make -DUSB_DEBUG=1;make unload;make
load'.

I won't be surprised if it didn't fix your disk though. You might try to
change UMASS_ADD_DELAY in

       { USB_VENDOR_OTI, USB_PRODUCT_OTI_JETFLASH2, RID_WILDCARD,
         UMASS_PROTO_SCSI | UMASS_PROTO_BBB,
         UMASS_ADD_DELAY
       },

to 'IGNORE_RESIDUE | NO_GETMAXLUN | RS_NO_CLEAR_UA'. Maybe
FORCE_SHORT_INQUIRY instead/in addition to these.

After modifying umass.c you need to rebuild and unload&load the kld. If
you have umass (or whole usb) in your kernel ('device umass') you should
comment it out, reinstall kernel and reboot. Then you'll be able to try
different quirk values.
