ALPS /dev/input/event* devices have:

bustype = BUS_I8042 (0x11)
vendor  = 0x0002
product = PSMOUSE_ALPS (0x8)
version = <protocol_version>

where <protocol_version> is following:

V1               = 0x100
V2               =      0x200
V3                      = 0x300
V3_RUSHMORE     = 0x310
V4                      = 0x400
V5                      = 0x500
V6                      = 0x600
V7                      = 0x700 /* t3btl t4s */
V8                      = 0x800 /* SS4btl SS4s */
V9                      = 0x900 /* ss3btl */
