USB regression: devices not initially recognized

[eschvoca]

Hi,

Using the Karmic beta of Ubuntu (linux-image-2.6.31-11-generic) my USB
keyboard and blutooth dongle no longer work on bootup.  If I unplug
them and plug them back in then it works.  I reported the bug here:

Hi,

When booting into Karmic my Blutooth USB dongle and USB to PS2
keyboard adapter are not recognized until I unplug them and plug them
back in. In my dmesg (see attachment for the full version) I get error
messages like:

[ 3.028029] usb 7-1: new full speed USB device using uhci_hcd and address 2
[ 3.148023] usb 7-1: device descriptor read/64, error -71

[ 5.088042] hub 7-0:1.0: unable to enumerate USB device on port 1

My USB mouse and USB sound card are correctly identified on boot-up.
Everything works fine in 9.04 so this seems like a regression.

Here is my lsusb after replugging the devices in:

And full dmesg is attached.

Let me know if I can test anything out.

Thanks.

Any suggestions on how to track down the problem?
