I was getting crashes here when descriptors ended up being null. I
believe the problem is that there are more possibilities for
gadget->speed than are actually handled. On my platform i used a patch
that will attempt to use any descriptor if one is available but I do
not know enough about the system to say whether or not that is a sane
solution. This at least stops null pointer crashes in the kernel.
