Kernel 3.2.1-{1,2} USB powered on Suspend?

I'm currently running kernel 3.1.9. When I go to suspend, my USB-powered laptop cooling fan also shuts off, and I checked the BIOS to ensure that the option for charging USB devices while the laptop is asleep was turned off.

If I upgrade to kernel 3.2.1-2, when I put my laptop in suspend, the fan remains on. When I downgrade to kernel 3.1.9, the problem disappears. I'm not sure what the problem could possibly be, I tried unloading the USB modules before suspend, to no avail. Thanks to all for any help!

**EDIT**
Fixed it...no clue why these modules were causing mischief, but I simply added the line

SUSPEND_MODULES="ehci_hcd xhci_hcd"

to the file /etc/pm/config.d/modules

and the power goes off when I suspend using pm-suspend.
