As far as I remember, this bug must have been fixed some time ago, as
the problem did not persist on the acer 1520 before I gave it away...
Marking as fixed. Please update otherwise if needed.
** Changed in: linux (Ubuntu)

Title:
USB devices not detected when hotplugged
Status in “linux” package in Ubuntu:
Fix Released
Bug description:
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.
