lsusb lists nothing and webcam gone -- romance ruined

[jidanni@jidanni.org]

Fellows, there I was all ready for a webcam call with my potential date,
but my romance was ruined by following "sid" too closely.

For the last month lsusb often doesn't list anything
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=626368

And now my webcam is broken too.
$ luvcview
luvcview 0.2.6
SDL information:
  Video driver: x11
  A window manager is available
Device information:
  Device path:  /dev/video0
ERROR opening V4L interface: No such file or directory

Yes, I know. Don't use sid if you want a love life.

I backed out of this too new kernel,

Any other tips?
