as I'm facing a similar problem (Canon Lide, though 25 instead of 110),
I would also like to know if there are news about this. See


http://thread.gmane.org/gmane.linux.usb.general/99815

for details about the hardware. If something is missing I'll try to
provide it. Its strange, that the same hardware (notebook and scanner)
works on one port, but not on the other).

I tried again today and all physical ports I can access are either
connected to Bus 03 (I suspect, that Bus 04 and Bus 03 are the same,
only differing in their speed) or Bus 02.

Bus 02 (Driver=ehci-pci/2p, 480M) works, Bus 03 (Driver=xhci_hcd/4p,
480M) fails.

Any ideas?

Greetings

Matthias
