With svn at revision 177, I can now get a picture when I do the skype

Any suspicious message in the kernel log ?

I posted more dmesg info just a while ago. Also another post about build
errors on revision 179.

Funny, if you look at the timestamps, your computer jumps back in time at this
point. Are you experimenting with time travel ? :-)

I don't know where those messages come from, I'll just assume they don't hurt
(they look related to memory management).

Basically, the EHCI scheduler says that the time slot that the URBs should be
queued for has already elapsed. This is a valid error when a device driver
specifies a time slot, but not when asking the EHCI scheduler to queue URBs
ASAP. I believe this is a bug in the EHCI scheduler. Could you try to push
the issue on the linux-usb-devel mailing list ?
