Hi,

I'm back on this, after a while away from home. Is there anything I can 
provide ?

To sum up:

- The LIDE110 doesn't work from SANE (git checkout from 10 minutes ago) + 
Linux (4.0.5): I only have problem with the scanner. Any other periphal I 
plugged in worked ok (mouse, usb card reader, usb disk drive, keyboard)…
- It works in Win7, virtualized in KVM, using the exact same USB3 port (seen 
as USB2 from Windows)
- It almost works when all debug traces are activated in SANE (it fails much 
later)

I am willing to capture anything you want, just tell me (and give me pointers 
to how to do the requested captures). I could even (but as a last resort, as I 
don't have space for it right now) install a Win7 on this machine.

Regards
