PCI/IRQ routing problem on Sony Vaio FX (i815E)

[Jörg Ziuber]

Hello,

USB on my laptop does not work, caused by an IRQ routing problem.

The laptop is a Sony Vaio FX (205/209/301/302 - all have identical
chipsets/ioports) 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 2.4.12
(unpatched source) both delivering the same results.

Someone out there, who can help the Sony owners ?

(If this is not the right forum or this discussion, please tell me whom
to contact.)

Bye,

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)

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.

Paul McAvoy ([e-mail]) confirmed this problem on his Sony with
other devices, as well as Leo AA ZZ ([e-mail]).
At this point the owner of 'usb-uhci', Johannes Erdfelt
([e-mail]), supposed an IRQ routing problem. 

Leo AA ZZ suggested a nasty solution:
Running KDE, the USB works, if you let the sound device (ARTs
soundserver) run, e.g. hear some good music while tranferring data from
your USB ZIP. But, of course, this cannot be the solution ! It should
work without that trick !

One question I was posed in another news-group, is for the Windows
interrupts - under Win2k they are the same: #9 for the USB hubs (see
printout below for Linux assignments).

APPENDIX

Probably useful outputs for further validation (on a system, NOT running
the sound trick):
