I am playing around with the usb host library,
I've tested with a few mice which are firmware set to 1000hz (even without any drivers) but the usb host library polls each of them at 500hz.
I watched around the sources, tried to change the interval in USBHIDParser::claim and some litle other changes, but I can't seem to find at all where this value comes from.

Any idea ? Is that something to do with the usb host hardware timer, I saw that notion while browsing the sources ?
