Comment # 10 on bug 1222186 from Javier de San Pedro

Suffering the same problem, but as far as I can see to me it is because of
these changes to the package:
https://build.opensuse.org/request/show/1163382#comments  , rather than any
kernel changes. 

I left a message there, but not sure since anyone is notified about it. I don't
know what the intention of the patch is but in addition to the /etc/vboxusb
type (which I didn't see either :) ) , setting 0660 to /dev/vboxusb looks wrong
to me. 

As I say on the message there, my recommendation is to just avoid doing these
chmod workarounds in the virtualbox packaging. I don't know if this was
introduced due to bug 1219766 or something else, but to me it doesn't sound
like something that should be workarounded silently in the virtualbox package. 

Just reverting these vboxusb chmod workarounds from the package (as in
https://build.opensuse.org/package/rdiff/home:javispedro:fixpkgs/virtualbox?linkrev=base&rev=5
) for me makes USB passthrough work again in TW.
