Hello once again...
I have been frustrated lately with trying to get my
Belkin Quadraport PCI USB card (OHCI) working. For
those unfamiliar folks, it consists of four separate
USB buses, each with a single port, on a single card.
They all share a single interrupt.
My problem is: the card is recognized fine, and each
of the four root hubs is recognized and shows up. Each
time I plug in a device, however, into any port, a
message similar to the following is shown:
usb_control/bulk_msg: timeout
usb-ohci.c: unlink URB timeout
usb.c: USB device not accepting new address = 8 (error
= -110)
The device never appears on the /proc/bus/usb/devices
list. I have tried every USB device I own, including
an unpowered hub. Everything seems to give the same,
or similar errors.
Since I know debug info is key, but I don't like
spamming the list, I have posted the following files
on my website:
http://www.brandeis.edu/~kgutwin/dmesg-5.13.2001.txt
http://www.brandeis.edu/~kgutwin/lspci-5.13.2001.txt
http://www.brandeis.edu/~kgutwin/devices-5.13.2001.txt
The errors can be seen at the bottom of the dmesg. At
the time, I had plugged into one of the ports an
unpowered hub and a serial port adapter into the hub.
I think my problem is rooted in the interrupts, since
I've seen the same type of error related to shared
interrupts and/or SMP. Unfortunately, I seem to be
forced to share my interrupt, because of the
quadraport card. What is the status of the interrupt
code, related to irq sharing?
Right now, I'm running kernel 2.4.3. I've also tested
2.4.0, which had the same errors. I'm in the process
right now of compiling 2.2.19 and testing it. However,
I need to use the usb-storage driver, so the 2.2
series, even if it works, won't be useful to me. When
I bought this card, I had the impression that it was
working - does anyone else use this card?
Any help would be appreciated.
Thanks,
-Karl
