Hello,
I contacted Tom Wang from Mustek asking him if I can release the SANE
backend under a GPL license. Here is the relevant part of his answer: "It is
ok to get the commands for the ASIC from source code. You can release the
SANE backend with GPL." So, it's OK, I can do it.
I also attach the result from sane-find-scanner -v -v. The relevant part
is this:

As for the error I get, description follows. If you look in the
attachement, you'll see these lines:
checking for SQ-1113 ...
this is not a SQ-1113 (Error during bulk write)
Yeah, I put SQ1113, but maybe I'll change it later... when I'll know the
chip for sure. Not important right now. The error I get is "Error during
bulk write". This happens during the call to usb_bulk_write. The definition
of this function is something like usb_bulk_write(libusb_handle,
bulk_out_ep, *buffer, size, libusb_timeout). It's easy to figure out what
libusb_handle and libusb_timeout stand for. I presume size is the size of
*buffer, but I don't know for sure few other things:
- what should I put in bulk_out_ep? Should I put 0x82 (bEndpointAddress
for endpoint 1)? It says "bEndpointAddress 0x82 (in 0x02)", it's "in", so I
presume it's for writing. And "bEndpointAddress 0x01 (out 0x01)" would be
for reading. Please correct me if I'm wrong.
- what should be the length of *buffer? I presume it's chip specific, do I
have to try different settings? As for the values that I should send, I'm
out of ideas. Maybe I should wait the sources from Tom Wang for this.
I will set up a web site as soon as I have some free time. This way, I can
keep you informed about my progress. If it's not finished until Friday, then
I'll do it in the week-end. My wife will be upset (again!), but that's life
:)
Thank you
Cosmin
