rum not detected if plugged in at boot

["Jeremy C. Reed" <reed%reedmedia.net@localhost>]

(Yesterday I posted this to tech-net. It was suggested I post to 
tech-kern instead. Please cc me on replies.)

When my rum0 device is plugged in at initial boot. It is not detected.
Even if unplug it and plug it in again, it is not detected.
My logs showed:

        uhub4: device problem, disabling port 5

If I reboot with it unplugged, then plug it in then it works fine.

My USB device is:

Any suggestions on how to get the device to be detected even if plugged in 
at boot?

This is on NetBSD 4.0 on i386.

It might be a different problem. With same USB device, on 4.0_RC4 on 
amd64, it is detected as:

ugen0: Belkin Belkin 54g USB Network Adapter, rev 2.00/0.01, addr 2

But no rum0 device known. (Should be rum0 instead of ugen0 I think.) I 
don't know if that is related problem.
