At openSUSE we use libusb-1 since openSUSE 12.2
(i.e. we use libusb-1 since about April 2012)
via "configure --enable-libusb_1_0".
I am not aware of issues because of this.

Regarding USB 3, see

It seems one needs a very current kernel for USB 3.
For me kernel 4.1.6 did not work with sane-backends-1.0.25.
For me kernel-vanilla-4.3.rc5 works where it seems
the xhci USB driver is now at least somewhat fixed.
But I needed additionally the workarounds for
the broken xhci driver in sane-backends-1.0.25
i.e. sane-backends-1.0.24 did not work for me
with kernel-vanilla-4.3.rc5, see
