(EV_REL), code 11 (REL_WHEEL_HI_RES), value -60 What I observe is that after resume the REL_WHEEL event type disappears, and the values are +7/-7 whereas before suspend (or after resetmsmice) values look completely different. So it looks like it is kernel related. As stated before I could reproduce it only on one laptop (Dell Latitude e6540) but not on my other hosts with the very same mouse. Rgds, Julien.
