Description Stefan Hoelldampf 2005-01-15 15:03:01 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

Description of problem:
Certain PCI/PCMCIA-to-USB2.0 cards with NEC chipset cannot be used with ehci, it dies and the systems uses the slow ohci.

Errors like the following can be found in the log:

> hub 5-0:1.0: USB hub found
> hub 5-0:1.0: 2 ports detected
> ehci_hcd 0000:03:00.2: fatal error
> ehci_hcd 0000:03:00.2: HC died; cleaning up
> ohci_hcd 0000:03:00.1: wakeup
> usb 5-1: new full speed USB device using address 2
> usb 5-1: not running at top speed; connect to a high speed hub

Kernel's bugzilla has a submitted patch for 2.6.11 which fixes the problem when rebuilding kernel-2.6.10-1.741_FC3.

The new kernel 2.6.11-1.14_FC3 fixes the problem as expected.
