Description Ralf Corsepius 2008-01-23 15:11:41 UTC

Description of problem:
kernel parameter "nousb" doesn't affect ehci_hcd (doesn't "not load ehci_hcd").

Version-Release number of selected component (if applicable):
kernel-2.6.23.9-85.fc8

How reproducible:
Always

Steps to Reproduce:
1. Add nousb to kernel parameters
2. reboot
3. lsmod | grep hci_hcd
  
Actual results:
Despite "nousb", the ehci_hcd kernel module is being loaded.
ohci_hcd and uhci_hcd aren't.

# lsmod | grep hci_hcd
ehci_hcd               39117  0 

Expected results:
ehci_hcd not to be loaded

That driver doesn't check for usb_disabled(). Test patch in rawhide.

Fixed in 2.6.24.3-12.
