If usb_set_address() ends in timeouts, something is bad with the
hadrware, most likely. Microcode crash in the device, perhaps.
Someone, I think it was Oliver, posted a patch that retries
usb_set_address(). It may help you, look in linux-usb-devel
archives.

Maybe it's a hardware problem, but this problem has never occured before Alan
started merging bits of 2.4.9 into his tree.

I've just tried all -ac1 kernels from 2.4.5-ac1 to 2.4.9-ac1
and the problem exists with all of them. So it would appear that
it didn't work reliably with earlier kernels either. I find it
interesting however, that it is much harder to trigger in
earlier kernels and that it doesn't happen every time.

I have seen a similar problem when I plugged in a creative nomad jukebox
(which was misbehaving with windows as well).  It had been behaving
properly in the past, but was of course an unrecognized usb device.
However this time it failed to get a device id assigned.  The solution:
replace the usb cable.  Turns out one of the wires had a break in it,
and would loose the connection in one direction if you didn't bend it
"just right".  if you have usb problems, treat it like scsi: blame the
cable first.  With a different usb cable all the problems went away
instantly and it accepted it's usb device id.

With the usb-uhci driver from 2.4.9-ac7 everything works well and
the problem never occurs.

What kernel is this?
What happens when you use the usb-uhci.o driver?

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.
