Do you mean that full speed and high speed devices don't work under 2.6.31.5
with the Fresco host controller? Full speed devices should work, because Greg
added this commit to the stable tree:
commit 2f670d465897b491da0b82fd8b047b9ec75bf8c8
Author: Sarah Sharp <sarah.a.sharp@xxxxxxxxxxxxxxx>

USB: xhci: Support full speed devices.
commit 2d3f1fac7ee8bb4c6fad40f838488edbeabb0c50 upstream.
Full speed devices have varying max packet sizes (8, 16, 32, or 64) for
endpoint 0. The xHCI hardware needs to know the real max packet size
that the USB core discovers after it fetches the first 8 bytes of the
device descriptor.
In order to fix this without adding a new hook to host controller drivers,
the xHCI driver looks for an updated max packet size for control
endpoints. If it finds an updated size, it issues an evaluate context
command and waits for that command to finish. This should only happen in
the initialization and device descriptor fetching steps in the khubd
thread, so blocking should be fine.

High speed devices should also work because they have a fixed endpoint 0 max
packet size. If FS/HS mass storage devices don't work, then please send me
dmesg from a 2.6.31.5 kernel with CONFIG_USB_DEBUG and
CONFIG_USB_XHCI_HCD_DEBUGGING set to yes.
