[sane-devel] CanoScan LiDE 220... on a Raspberry Pi.

[Kelly Price]

Heya all,

I figured with the issues with USB 3.0 over xhci that I see if I could
get it to work on a Raspberry Pi, which uses not ehci but dwc_otg for
driving the USB bus.

In summary, though:

* First connected to a Pi 3B+: failed with same error as USB 3.0 over xhci.
* Connected to a Chromebook with USB 2.0 ports over ehci: works 100% with xsane
* Connected to a Pi 2B: works 100% with scanimage
* Connected back to the Pi 3B+:  now works 100% with scanimage

Maybe some initiation has to happen over ehci for it all to work
properly.  Weird.
