[Bug 564459] [NEW] USB devices not detected when hotplugged

[Ric Flomag]

Public bug reported:

Steps to reproduce:
* boot with usb device unplugged (mouse, usb stick, external hd)
* plug the usb device

Observed: device not detected (usb stick or hd not mounted, mouse doesn't work).
Expected: device ready to use.

NOTE: vanilla kernel linux-image-2.6.32-02063211-generic_2.6.32-02063211_amd64 does behave normally: hotplugged devices work as expected.
NOTE: usb devices work as expected if plugged before booting.
NOTE: this bug affects karmic kernels too. I'm not sure if it is an update regression.
NOTE: I can confirm this bug on two different acer laptops (the Aspire 1520 used to report it, and an Aspire 4520)
NOTE: This bug supersedes bug #425755: the original report is the same as bug #435352 (fixed), but most of the comments seem to confirm this present report.
