Two bad experiences using sane-pixma for Canon PIXMA MX360:

1) USB cabling

Using a longer, non-shielded USB-cable (connected directly to my
machine) I got this error
  scanimage: sane_read: Error during device I/O
  Scanned page 1. (scanner status = 9)
immediately returning to the command prompt. Then the scanjob began (ADF
begun feeding the paper), and after a few seconds - presumably after the
MFP memory was full or some IO timeout of the device - the paper was
stuck in the middle of the ADF. With shielded USB-cable I had no
problems at all, although it was connected to a USB-hub. This behaviour
was reprodicible some hours later. (I've not tried neither the long
cable on the USB-hub nor the short directly on my host.)

2) ADF having no more paper leads to timeout and necessity to restart device

Scanning via ADF works fine, both with scanadf and with scanimage -b,
just when all pages have been scanned a timeout error is reported and I
have to switch off and on the device to be able to continue.

Below I've copied a command line and part of the debug output; I had
only 1 page in the ADF. When I scan more pages, the "underrun detected"
appears after each page has been done.

I found a rather similar bug, however the solution offered there will
not work since I'm using yesterday's git:
https://alioth.debian.org/tracker/?func=detail&atid=410366&aid=312353&group_id=30186

How can I further debug the issue or what can I try out?

Cheers,
ibu
