Having any USB problems?

[axel_2078]

I've seen posts in here of people having problems booting their computers due to a USB keyboard or mouse, only to have the problem vanish after switching to PS/2. I found this info on www.mandrakelinux.com and thought I'd post it. I don't know how helpful it will be. Tell me if you guys think it has any relevance to the problem.

 

Error scenario: Some motherboards based on VIA chipsets have USB-related problems with 2.6.x kernels.

Why: This problem is due to USB support with these motherboards, although the number of problematic motherboards is decreasing with each new kernel revision. You can see evidence of the problem with boot-time syslog messages such as:

 

 

usb 1-1: control timeout on ep0in

 

and

 

usbfs: USBDEVFS_CONTROL failed (...) ret -110

 

Solution: Add any or all of the following boot kernel parameters to your /etc/lilo.conf file: "acpi=off", "noapic", or "nolapic". Execute "lilo -v" to update the LILO configuration. After boot, execute the following commands:

 

# modprobe -r uhci-hcd

# modprobe uhci-hcd

 

You may also elect to use the 2.4.x kernel.
