Weird behaviour of usb printer (drivers/usb/class/usblp.c: usblp0: error -110 reading printer status)

[Georg Schild]

Hi List!

I have some problems with my usb printer with the latest kernelversions. 
Don't know which kernelversion it started but after a while (one or more 
days) the printer connected via usb stops working and this message fills 
up /var/log/messages:

drivers/usb/class/usblp.c: usblp0: error -110 reading printer status

I am using a gentoo-system on an AthlonXP machine. I have tried several 
kernelversions, some with included patchset from gentoo and some vanilla 
kernels. I don't know with which version the problem started, i think 
somewhere at 2.6.8 but this is not exact. To solve the problem i can 
only reboot the machine, switching the printer off and on again is not a 
solution. Other usb-devices still work. Printing system is cups. When 
the messages appear the systemload gets up to something over 50%.

Any suggestions on this problem?

A known problem. Also very rare, unfortunately.

You are making a usual mistake here. It is essential for you not to
cover the widest possible field at this point, but to name AT LEAST ONE
version which is proven to have this defect. Please do so.

Also, please send your /proc/bus/usb/devices.

Okay, i am sure that 2.6.9-rc3 has this mistake

Here the output. The printer is accepted and works at this moment. 
Current kernel is 2.6.9, don't know if the failure still exists though i 
  am using it just for about 2 hours yet and until the mistake almost 1 
day has gone. I will tell immediatly if the error doesn't come up again. 
If someone needs some more information just tell me.

Thanks for response
