Because there are many stop/start feeding occur in the same time, driver frequently failed to restart feeding, thus result in no packets sending to enhancement; if a multifinger-gesture has been generated with cursor suppressed, the cursor will keep suppressing as no packet with finger count info to un-suppress cursor. do not stop/start feeding finger packets when just changing edge motion speed.
