Hello,
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 have identical chipsets) with a
i815E-chip including Intel 82820 820 (Camino 2) for the USB, and 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 (4 checked) plugged to the
laptop.
* The same devices work under Linux on other computers (desktops), with of course
other chipsets.
* 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.
Important outputs for further validation:

Johannes Erdfelt supposed an IRQ routing problem (well I don't understand, what this
means) and was asking for the Interrups under Windows: they are the same, i.e. #9.
Is there a solution for such a problem ?
Can I hope to get USB working under Linux or do I have to live with this
non-functionality ?
Bye,
