// sorry for double-post I was advised to use 'reply to all' and wasn't
sure if the prev. message was forwarded to linux-usb
Thank you for the reply.
I'd be bold enough to categorize this as a problem, since the usb hub
doesn't work.
It could be 'expected' if it were a RC version of the kernel but the
problem exists since the version 3.8
(don't want to go back because previous versions had problems with my
intuos tablet)
Should I be investigating this issue myself? Since the hub is working
correctly with previous kernels, I assume that the updated kernel module
is to blame not the hub.
Here is addiotional info, not sure if that's useful....

Since kernel 3.8 Apple Cinema Display's usb hub spits errors randomly at
boot. (their count seems to be random, but the type of the error is
always the same)
As soon as I disconnect the usb extension cable the errors are gone.
Errors
journalctl
usb 1-2.2: can't set config #1, error -71
hub 2-2:1.0: hub_port_status failed (err = -71)
hub 2-2:1.0: hub_port_status failed (err = -71)
hub 2-2:1.0: hub_port_status failed (err = -71)
hub 2-2:1.0: hub_port_status failed (err = -71)
.....
Is this a problem or is it the expected behavior?
If you want to investigate further, build a kernel with
CONFIG_USB_DEBUG enabled and post the output from the dmesg command
showing what happens during boot.

Yes, you should investigate the problem. If you don't, nobody else
will.
