urb timeouts with eagle on 2.4.20

[Piotr Szymański]

Hi,
I have a problem with my sagem 800 modem on my USB Controller: VIA 
Technologies, Inc. USB (rev 10), using kernel 2.4.20.
After connecting to the net, the modem disconnects and I get an error:
***
Sep 27 12:51:56 niedakh NETDEV WATCHDOG: eth0: transmit timed out
Sep 27 12:51:56 niedakh [Adi] Transmit timed out!
Sep 27 12:51:56 niedakh [Adi] transmit URB e5cce0bc cancelled
***
I have to reload its firmware in order for it to work again. 
I talked to manypeople about this. I was told to try booting with noapic or 
acpi=off. Unfortunately the same error happened with apci=off or  noapic or 
even both.  On eagle forums I was pointed to check my controllers altency 
(how do you do that?) which reminded me I had a similar situation on win2k on 
the same machine, but after installing via 4in1 update for usb it started to 
work properly on win2k. i google for "usb via latency" and found a via usb 
latency patch for windows, I didnt find a linux version of the latency patch 
for via anywhere.
Noone around knows how to fix this, so Im mailing here.
Thanks for any replies.

  Ofcourse, you can use powertweak utility too.

  hmm, this sound interesting. So, did you tried use uhci usb adapter
instead of usb-uhci? Maybe it will works better.

Cool, thanks for the tip, last thing remaining (maybe you know thisas well), 
what value should I to set it to?

  less value is less latency, you can try 0 instead of 32. But if via
has got any problem with their HW which is workarounded in m$win...
maybe this will not help you :*(

  And what about other USB devices? e.g. USB flash disks works fine?
