Yep, I'm the Kubuntu dude ;)

Same problem as above.  There is also an earlier reference in the mailing l=
ist archives back in February, I think, that I found.

I have been digging around looking at the problem.  What I do know is that =
a lot of people are having problems with USB on Ubuntu / Kubuntu with the K=
ernel 2.6.20 (Fiesty).  The general consensus seems to be that it is due to=
 the kernel config CONFIG_USB_SUSPEND=3Dy which is marked as 'experimental'.

I've considered recompiling the kernel with CONFIG_USB_SUSPEND=3Dn, but the=
re are very sketchy instructions on recompiling kernels in Ubuntu.  So I've=
 decided to wait and see if it gets fixed in the short term.
