Hello,
first one short question as an abstract of the following (I hopefully detected the
problem right):
Is there a USB support for the i815E/Intel 82820 820 (Camino 2) chipset (one of these
all-in-one chips) ?
Is it possible to set the two usb-uhci modules on different interrupts ?
Please help,

The problem in detail:
Attaching any USB device to my laptop, I get a response (/var/log/messages) in
USB-debug mode:
kernel: hub.c: port 2 connection change
kernel: hub.c: port 2, portstatus 100, change 1, 12 Mb/s
kernel: hub.c: port 2 connection change
kernel: hub.c: port 2, portstatus 101, change 1, 12 Mb/s
kernel: hub.c: port 2, portstatus 103, change 0, 12 Mb/s
kernel: hub.c: USB new device connected on bus1/2, assigned device number 2
kernel: usb_control/bulk_msg: timeout
kernel: hub.c: USB new device not accepting new address=2 (error=-110)
kernel: hub.c: port 2, portstatus 103, change 0, 12 Mb/s
kernel: hub.c: USB new device connected on bus1/2, assigned device number 3
kernel: usb_control/bulk_msg: timeout
kernel: hub.c: USB new device not accepting new address=3 (error=-110)
The laptop is a Sony Vaio FX (205/209/301/302 - all identical) with a i815E-chip
including Intel 82820 820 (Camino 2) for the USB, an with two accessible USB ports.
The test system is a SuSE 7.2, Kernel 2.4.4 (SuSE source) and 2.4.10 (unpatched
source) both delivering the same results.
Validation:
* This problem occurs under Linux with _any_ USB-device plugged to the laptop.
* The same devices work under Linux on other computers (desktops), with of course
other chips.
* The same devices work under Windows with the laptop without any problem.
* The tests (Linux) have been performed with usb-uhci, and uhci (usb-ohci not
starting).
=> I have no hardware problem, but a software problem.

------------------------------
Summary:
Here we have:
* No interrupt conflict between different devices.
Only the fact of two usb-uhci on one interrupt (#9) is different from other PC's,
where I have tested the hardware under Linux. So, this might be the reason for the two
outputs in /var/log/messages.
* The usb-uhci works in the same area (ioports) as under Windows.
* The problem that occurs is not depending on the plugged USB device, so there is a
USB driver basic problem.
* As I have seen so far in the net, the /var/log/messages timeout-output is due to a
driver non-support of the hardware.
But, because the hardware is detected correctly and the usb-uhci driver starts and
initalises correctly (does it really ?), I have the hope that there can be a solution.
Probably, the problem are the two usb-uhci modules running on the same interrupt. Can
this be set to different interrups on startup ?
Can somebody help me?
Bye,
J. Ziuber
