I don't know for certain in your case, but when I was playing with the ALPS Glidepoint pointing device a few years ago, this all made sense. There wasa bit in the first byte of the mouse message (0x80, I think, but could be wrong), which is "always" set and used to help find the first byte of the multi-byte mouse message. The ALPS touchpad device would set this to zero to indicate the "tap" gesture on the pad. I think this explains why the code is the way it is in the mouse driver. I don't know why your device would behave differently. As you observed, there's a lot of whacko PC hardware that has only a passing similarity to other stuff. Perhaps this is the "added value" your vendor has chosen to give to you :-) louie To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
