As a result of that, the USB controller driver gets wedged.
This looks like a hardware problem with your USB controller. Please try
the latest kernel; there were added some workarounds recently.
You might also try connecting the device through a hub (but there are
some bugs in the EHCI driver which might make it think that it cannot

Don't anthropomorphize computers; they don't like it.
