Author has been informed, says they are working on a fix. Also occurs in
Linus' tree.

Steps to reproduce:

modprobe ohci1394

Comment 1 Andy Dustman 2002-11-19 14:12:28 UTC

This definitely occurs in Linus' tree as well, as stated in the original report.

Comment 2 Greg Kroah-Hartman 2002-11-19 18:28:39 UTC

This is a IEEE-1394 (Firewire), not a USB bug.  We need to add this as a category.

Comment 3 Andy Dustman 2003-03-03 08:43:35 UTC

Looks to be fixed in 2.5.63 or possibly earlier.
