OK, let me back up a little bit, please. My point is that SCSI emulation did
not work for me with the Apacer. Everything worked correctly with SCSI
emulation with 2.6.8.1 (still on Debian/sarge), and then when I have
re-compiled 2.6.9.1, I think I have not missed anything (see attached
output from lsmod). Apparently the device is correctly recognized (see
output from lsusb), but there is nothing in /proc/scsi/scsi and mount -t
vfat /dev/sda /mnt/bizu loads SCSI modules (the output of lsmod was
captured after attempted mount), but it fails with '/dev/sda is not a valid
block device'. In this situation I have not found anything helpful on
Google (both www.google.com and groups.google.com) so I settled
for /dev/uba solution which at least worked. However, it is really slow and
when I routinely transfer tens of megabytes with this stick, it takes
really a lot of time to make to update my Debian from the USB stick, so
after all I would like to get SCSI working (if it is faster and it allows
USB 2.0).
Is it possible to run USB storage with 2.6.9.1 over SCSI emulation? How to
make kernel using ehci_hcd instead of uhci_hcd?
Thanks for any suggestion,
Matej

A conclusion is simply the place where someone got tired of thinking.
