Good morning,

If I keep them loaded during suspend:
[...] Suspending devices uhci-hcd 0000:00:11.2: suspend to state 3 drivers/usb/host/uhci-hcd.c: dc00: suspend_hc hwsleep-0257 [10] acpi_enter_sleep_state: Entering sleep state [S3] Enabling SEP on CPU 0 Back to C! Devices Resumed uhci-hcd 0000:00:11.2: resume [...] drivers/usb/host/uhci-hcd.c: dc00: wakeup_hc
Mouse doesn't work, unplug:

Further attempts to un/re-plug the device show no response.
(Same with Canon Powershot instead of Logitech USB Mouse)

In my case it is an Epox 8kha+ board, the problem should not be hardware specific since Suspend To RAM works under WinXP.
I will try S4 lateron.
