Comment 1 Alan 2009-09-23 00:12:31 UTC 
USB serial fixes went into -next and the git head so should end up back in .31 soon - known bug tho
Comment 2 Greg Kroah-Hartman 2012-02-22 21:47:05 UTC 
All USB bugs should be sent to the linux-usb@vger.kernel.org mailing 
list, and not entered into bugzilla.  Please bring this issue up there,
if it is still a problem in the latest kernel release.
