i've being playing with the trivial "add-the-missing-ids" patch today, and i
realized that there is a hardcoded device-id in the cs2_open function, that is
why your patch was not not even reporting a connected scanner for me:
LS50 / 5000 have device ids of 0x4001 / 0x4002  while apparently all the other
usb-coolscans(only the LS40?) have 0x4000.

With this add'l patch now the scanned is detected, and if run 
   scanimage -d coolscan2:usb:libusb:001:002 --ae 
then the scanner does all the scanning noise for a while, but ends however with
a IO_ERROR:

Error: cs2_issue_cmd(): Unexpected non-data phase, but n_data != 0.

The same happens if i run scanimage without options, the error cames pretty soon
in this case:

-------------------

Actually cs2_phase_check() returns CS2_PHASE_STATUS, but with n_data == 11838

Any suggestions for further tests/debugging info is welcome.
