Possibly strange Plustek model not working with sane-1.0.7 beta1

Hi,
I think I've got something that might be interesting/relevant to the
cause of creating robust Plustek USB drivers:
I've got a Plustek OpticPro UT12 (at least that's what the label
says...), but it seems to be different from the models that Kev Green
has put his hands on...
First of all, my model has a product id==0x0013, not 0x0017 ! See
attached file, "proc_bus_usb_devices" to verify that (It's a cat of my
/proc/bus/usb/devices).
Scanner's serial number (printed on the label at the back, below the
barcode) is 52F707043539, it has been bought in Poland. Another sticker
at the side has "PL20-08-2202" printed on it.
I've corrected the prod id in my plustek.conf (see attached file,
plustek.conf_excerpt) and in options to the scanner.o kernel module (by
adding "options scanner vendor=0x7b3 product=0x13" to /etc/modules.conf).
Second, it seems that with drivers included in sane 1.0.7 beta1 the
scanner doesn't work properly.
sane_find_scanner found the scanner correctly, but scanimage (and kooka,
and other sane clients) have a problem:
They succeed in connecting to the scanner, the lamp turns on, but motors
stay still. The scanning process freezes, and after a while I start
getting messages about USB timeouts:
usb_control/bulk_msg: timeout
Scanimage then has to be terminated. After sending a TERM signal to it,
I must wait a significant amount of time before the scanimage program
exits. Sometimes I even have to use KILL signal.
After this, there's something wrong with USB, cat /proc/bus/usb/devices
shows only devices that precede PLUSTEK on the list, then cat freezes
and I start getting USB timeout messages again and have to kill cat.
Usually, physically plugging the USB scanner out then back in restores
proper operation (that is, I can cat whole /proc/bus/usb to the end).
I'm attaching a few files (I hope attachments are acceptable on this
list...) that will give additional info about my problem:
plustek.conf_excerpt - my plustek.conf file, stripped of comments.
proc_bus_usb_devices - output from "cat /proc/bus/usb/devices"
before it gets jammed with scanimage
scanimage_-T.bz2 - bzipped output from "scanimage -T > scanimage_-T
2>&1". I've set SANE_DEBUG_PLUSTEK=12 and SANE_DEBUG_DLL=12 as Kev
Green advised in the Plustek-USB.txt document.
strace_scanimage_-T.bz2 - bzipped output from "scanimage -T >
strace_scanimage_-T".
var_log_messages - messages from my /var/log/messages that I
think are related to the problem.
