Hi,
I'm sorry to have to bother you with the following (probably boring)
problem, I read about similar problems on the mailing list archive
but none of the answers helped and I haven't seen the error I get while
unloading the module before:
I have a Gericom notebook and have tried (unsuccessfully) to get USB
working on it with a lot of kernel versions, now it's running kernel 2.2.15
with the backport from 2.3.99-pre7 (2.4.0-test1 behaves similarly).
lspci:
00:00.0 Host bridge: Intel Corporation 440BX/ZX - 82443BX/ZX Host bridge (rev 03)
00:01.0 PCI bridge: Intel Corporation 440BX/ZX - 82443BX/ZX AGP bridge (rev 03)
00:07.0 Bridge: Intel Corporation 82371AB PIIX4 ISA (rev 02)
00:07.1 IDE interface: Intel Corporation 82371AB PIIX4 IDE (rev 01)
00:07.2 USB Controller: Intel Corporation 82371AB PIIX4 USB (rev 01)
00:07.3 Bridge: Intel Corporation 82371AB PIIX4 ACPI (rev 03)
00:0a.0 CardBus bridge: Texas Instruments PCI1225 (rev 01)
00:0a.1 CardBus bridge: Texas Instruments PCI1225 (rev 01)
00:10.0 Multimedia audio controller: ESS Technology ES1978 Maestro 2E (rev 10)
01:00.0 VGA compatible controller: ATI Technologies Inc 3D Rage LT Pro AGP-133 (rev dc)
20:00.0 Ethernet controller: Digital Equipment Corporation DECchip 21142/43 (rev 41)
It loves to share almost everything on IRQ 10 (The video controller, the
cardbus bridge, the ethernet card - and the usb controller) with only small
differences if PnP-Support in the BIOS is on or off. M$ Win98 uses the same
setup - USB works there (tested with the Terracam USB).

As you can see from above, no interrupts are produced by usb-uhci.
If a device is attached the following happens:
kernel: usb.c: USB new device connect, assigned device number 2
kernel: usb_control/bulk_msg: timeout
last message repeated 4 times
kernel: usb.c: USB device not responding, giving up (error=-110)
kernel: usb.c: USB disconnect on device -1
# modprobe -r usb-uhci
produces:
kernel: usb.c: USB disconnect on device 1
kernel: usb.c: USB bus 1 deregistered
kernel: kmem_shrink: Invalid cache addr c7fefaa0
kernel: kmem_destroy: Can't free all objects c7fefaa0
kernel: usb-uhci.c: uhci_desc_kmem remained
kernel: kmem_shrink: Invalid cache addr c7fefb00
kernel: kmem_destroy: Can't free all objects c7fefb00
kernel: usb-uhci.c: urb_priv_kmem remained
kernel: usb.c: deregistering driver usbdevfs
kernel: usb.c: deregistering driver hub
Any suggestions what I could/should do?
TIA
