I tried Eko's 10994 build posted in this forum on my 350N v1, and although the error -71's are gone and it seems to be picking up the USB controller properly on each reboot, I'm still getting the "Data Integrity Not Assured" message in dmesg when attaching a storage device.

Still doesn't appear to like the embedded EHCI controller. Storage mounts w/o error (as before) and quick testing reveals no data corruption (yet), but disconcerting if storage is to be used as a network backup medium (data corruption = bad).
Any changes to the EHCI controller driver since 11/28/08?
