SubjectUSB device not accepting new address

Hello,

I have just come across another USB address problem, which happens sporadically
and is not easy to reproduce. It happens sometimes during bootup and is unrelated
to port overpowering, at other times everything works well. Output below.
The USB driver is the JE-driver.

Regards,
-Udo.
