Yes I figured it was a hardware problem, but that was not really the

What do you propose as a trigger for the kernel to fallback?
You can work it around manually, just don't use ehci-hcd, can't you?
Yes I can unload ehci-hcd, but I have one USB 2.0 device that strangely
enough DOES work as such, and unloading ehci-hcd will cause that also to
run at 1.1 speed.
Clearly something is failing when plugging a device with ehci-hcd
loaded, the driver seems to keep retrying indefinitely. Instead it would
be nice if after a few tries it hands the device over to uhci-hcd. This
seems to be the behaviour under Windows, so I was wondering if Linux
could be made to do something similar.
