Let me know if there's anything else I can do.
Thanks,

Same problem with versions 1.0.23-3ubuntu3.1 and

I do have the scanner working correctly in Windows (in VirtualBox)
with the vendor drivers.
Any ideas? Is there anything else I can do to debug it? Would
it be
helpful to get a USB trace (of the Linux and/or Windows cases)?
Thanks,
Robert
Hello,
it is slow and difficult to add support for a scanner just by
exchanging USB log. However, having a log could give us an
estimate of the work to do:
see https://github.com/stefdev49/syseneg/analyze/README.md for
a start. Then post the pcap file in some place where I can grab it.
Regards,
Ste
Hello,
thanks for the data. I have to update my decoding scripts to handle
GL841 USB protocol before I can analyze the log. I'll let you know when
it is done.
Regards,
Stef
