Yes it is iMac G3. More or less sth like this:

I'm seeing the following error message when I have a wireless usb
ethernet adapter plugged into an embedded PPC SoC. If I plug the
adapter in after the SoC has booted the device is detected w/o any
issue. Which makes me thing that there is some initialization timing
issue.

Not that it'll help much: the VM calls throttle_vm_writeout()
for GFP_NOIO
and GFP_NOFS allocations, which is a bug. Because if the caller
holds
locks which prevent filesystem or IO progress, we deadlock.
I'll fix the VM if someone else fixes USB ;)
What else needs to be fixed?

In some systems we may have both a platform EHCI controller and PCI EHCI
controller. Previously we couldn't build the EHCI support as a module due
to conflicting module_init() calls in the code.

Let me test this patch out. I'm ok with the changes for handling

On the MPC834x processors the multiport host (MPH) EHCI controller has an
errata in which the port number in the queue head expects to be 0..N-1
instead of 1..N. If we are on one of these chips we subtract one from
the port number before putting it into the queue head.

Is there any reason that we need to keep support for
