[sane-devel] Canon TS8050 not working correctly

[Rolf Bensch]

Hi Martin,

You can use wireshark with usb extensions:
https://wiki.wireshark.org/CaptureSetup/USB . You don't need to install
Windows in a VM.

Please provide a complete Windows USB scan session as compressed file
(e.g. zip or 7z) and a new linux logfile created with
SANE_DEBUG_PIXMA=21 xsane &> pixma.log.

Hope this helps.

Cheers,
Rolf
