On .39 I get the output below. On 3.0.0, the lsusb process hangs.
lsusb -v with no device shows other devices, but hangs on this one.
Also, no other usb devices work in 3.0.0 (e.g. no USB mouse)
P.S. Thanks for the *fast* response (Jonathan thought he was slow to
respond). This isn't a critical system for me, and I can back down to
a previous version, so it's not crunch (in fact because it's for my
mother I'm thinking of tring Squeeze with only an updated alsa libs
(apparently the version of alsa in squeeze doesn't work with at least
some intel hda sound which is why I was experiment with wheezy for her
in the first place), for the stability.
