Hi! Thank you for information. Your PS/2 Aux Port Control description seems to really matches. Just there is reverse order of bits. Bit 0 in description is highest, therefore matches BIT(7) macro.
Bit 6 in description (BIT(1) in code) describes SP Extended Mode which alps.c enabled. And in that description is written: "If 1 SP is extended packet format (driver must set SP raw mode and GP absolute mode)." Do you have any idea what "SP raw mode" is? How to set it? For me it looks like it could be that extended mode of trackstick itself. "GP absolute mode" I guess is GlidePoint absolute mode, therefore enable 6 byte absolute mode for touchpad. And for Bit 7 (BIT(0)) is written: This bit is used with the PS/2 Aux port to use the Pass-Thru mode ( see appendix A ). Do you have some information about this appendix A?
