In polling mode lifting finger is not always detected

[usr-sse2]

Describe the bug
When I was using polling mode, VoodooI2C often reported finger as still present on the touchpad when it was actually lifted. It doesn't happen in GPIO mode.

My best guess without looking at code is that the polling function misses the finger lift or the hardware is not properly reporting the finger lift events.

I am not as familiar with the polling code in VoodooI2CHID. I'll take a look sometime next week.
