Hello,

I am having an interesting conflict between USB and the CPUfreq driver for P4 
mobile in my laptop... (Compaq Evo N610c)

When I have both enabled, and the CPUfreq set to use the "userspace" governor, 
hid-core crashed with the following error every time I click the mouse buttom 
more than once in a second. (so double clicking is a pain) I have not had any 
other USB actions cause this crash, such as using my USB connected wireless 
card.

(from dmesg)
drivers/usb/input/hid-core.c: can't resubmit intr, 0000:02:0e.2-4.1/input0, 
status -32

After this error I have to rmmod ehci_hcd && service usb restart to make 
anything usb work again.

I have also noticed that the frequency of the processor will not scale below 
1196mhz (processor is a 2.0ghz P4 mobile) when ehci_hcd is loaded, but it 
will scale all the way down to 130mhz when this module is not loaded...

Any ideas on what may be causing the problems?

Thanks,
