@Troy S.:
Sure thing. This is the relevant lsusb line for my controller, on an ATI
SB600 mobile board:

Bus 004 Device 002: ID 05e3:0606 Genesys Logic, Inc. USB 2.0 Hub /
D-Link DUB-H4 USB 2.0 Hub

With ehci_hcd loaded, devices _mount, but choke out even after applying
the max_sectors tweak_. I then have to blacklist ehci_hcd and reboot to
restore USB 1 functionality.

Offhand, I believe we've seen this "Genesys" name before, earlier in the
thread.

Full lsusb output attached, just in case.
