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)
       Status: Incomplete => Fix Released

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.
