Re: [PATCH] hid-core: Configurable USB HID Mouse Interrupt Polling Interval

[zyphr]

Something looks odd.
I've tested this with 2.6.11-rc3-bk5 + your lasted patch

cat /sys/module/usbhid/parameters/mousepoll says it's at 2ms
but if I check /proc/bus/usb/devices it's reading 10ms

I've used parameter under /etc/modules (debian sarge)
in there I have added: usbhid mousepoll=2

this used to work ok with:
http://omfg.linux.dk/pub/configurable-hid-mouse-polling/archive/chmp-r5-add-modparam.patch

rmmod usbhid and then "modprobe usbhid mousepoll=x" with a different value,
does change the vualue under /sys
but under /proc/bus/usb/devices it keeps reading the same value (10ms)
I also tried replugging the mouse, the value's stay the same.

I am just a just user, so maybe I did something wrong =)

Thanks,

Joep
