kernel 2.6.0 - USB: uhci_hcd problem after suspend...

Dear All,

I upgraded to kernel 2.6.0 (due to problems with the sound) and exchanged
that against an USB problem:

I use a Fujitus Stylistic Tablet PC with a [lspci -v]

00:07.2 USB Controller: Intel Corp. 82440MX USB Universal Host Controller
(prog-if 00 [UHCI])
        Flags: bus master, medium devsel, latency 64, IRQ 9
        I/O ports at 1880 [size=32]

chipset.

I compiled USB support ( tried both as modules and inside the kernel) with
uhci hcd support for the above chipset (and the pl2303 driver for my GPS
device).
After booting everything runs smoothly and I can use USB without problems.

However, when I suspend the machine (using APM) it 'forgets' the USB support
completely, i.e. even with the device unplugged at suspend. (see
/var/log/messages below)

Have I overlooked something?

Thanks,

Frank
