next in thread | raw e-mail | index | archive | help
since usb mass storage driver (umass.c)
is tied to scsi stuff, i am posting to
see if anyone may be able to direct
me to bring about a solution to this problem.
from the following, i assume i the link/controller/camera
are operational to some extent - as the camera ID is
detected just fine by the driver as well as
userland programs.

QUIRK=command status signature fix, 0x5343->0x5542)

without umass0 (USB mass storage driver) being able to
complete it's task, i cannot mount the camera's smartmedia
disk. supposedly this camera supposedly has "the convenient
Auto Connect USB feature lets your computer automatically recognize
your Brio Zoom D-150 so you don't have to install any additional
software". so i think i should be able to mount this camera.
i don't have windows, and don't know of bsd/unix USB snoop software.
the failure is in this function - a status state machine.
i can't find a calling function, so i assume it's installed
as an interrupt handler (i don't know too much about how
unix installs handlers/remaps interrupt signals).
umass.c:

printf("OLYMPUS - TSTATE_BBB_RESET1\n");
printf("%s: BBB reset failed, %s\n",

}
umass_clear_endpoint_stall(sc,
sc->bulkin, sc->bulkin_pipe, TSTATE_BBB_RESET2,
sc->transfer_xfer[XFER_BBB_RESET2]);
return;

if (err) { /* should not occur */
printf("OLYMPUS - TSTATE_BBB_RESET2!\n");
