It does not, as far as I know.

That looks normal. But the kernel log shows that this device has some trouble getting started. It eventually settles down, but for a while there it doesn't work properly.

Nevertheless, even a malfunctioning device shouldn't provoke the kernel into a WARNING like you got. The underlying reason for it is not at all clear, particularly since you didn't enable usbcore dynamic debugging -- although that might not provide enough information either.

One thing you could try doing is simply to replace that hub.

Alan Stern

Replaced the hub with a similar one which probably has same chip inside, and the same problem happens. Which kernel cmdline parameter would enable the debug you want.

dyndbg="module usbcore =p"

However, I'm far from certain that this will be very helpful. :-(
