We are trying to run a web app on BBB via a browser in kiosk mode, and have
ran into a significant CPU load (20% with plain xterm on X11) when using
touchscreen or mouse. Situation gets worse if we actually run a web browser.
Then we have found using different mice produced different CPU loads, so we
ran evhz which showed 133 Hz for one mouse, 1000 Hz for another, and
500-1000 Hz for touchscreen.
For the mice, usbhid.mousepoll option configures the polling interval used
by the usbhid driver/kernel module, and we had successfully set the
intervals for USB mice.
However, for the TI touchscreen driver, no such configurable option has
Is there any way to lower the polling interval, perhaps with a compile time
