I can add the following:

2) I just tested the copy of the small files using the ICY DOCK
MB981U3S-1S connected to my ReadyNAS 102 *on a 3.11.7 kernel*
and it completed successfully. 

2) on current 3.13.0-rc7 kernel (w/ Bj?rn patch applied just in case), I
just transferred 40GB through a Logitec LAN-GT JU3H3 (it is based on an
ASIX AX88179) connected to my ReadyNAS Duo v2 (NEC XHCI controller) at
an average rate of 82MB/s. Bottom line: no issue. When I try to do the
same on my ReadyNAS 102, I immediately get complaints:

If someone has a system w/ a Fresco Logic FL1009, I would be interested
by some feedback on how it behaves w/ current kernel.

Cheers,
