No, I've not used it for a while. I did install drivers for it at first
but I didn't find it dependable enough. You could see from the usbtree
output there is/was no driver loaded for it.
Hmm, ok. Can you try the following patch and paste the whole output
from the tool? The code to check for device inactivity is a bit of a
kludge, and might not work well if your machine is very slow or there's
a lot of activity going on.
