>Description:
I'm tested two mouses A4Tech X-750BF and X-750MF.
When they plug throught ps/2 jack they absolutely doesn't work neither under moused nor under x.org. When plugged throuth usb all works fine.

For example X-750BF:

ps/2:
Dec 12 19:13:02 home kernel: psm0: current command byte:0065
Dec 12 19:13:02 home kernel: psm0: <PS/2 Mouse> irq 12 on atkbdc0
Dec 12 19:13:02 home kernel: psm0: [GIANT-LOCKED]
Dec 12 19:13:02 home kernel: psm0: model Generic PS/2 mouse, device ID 0-00, 2 buttons
Dec 12 19:13:02 home kernel: psm0: config:00000000, flags:00000008, packet size:3
Dec 12 19:13:02 home kernel: psm0: syncmask:c0, syncbits:00

No any activity for all possible moused/xorg options (including -f 200 for moused)

usb:
Dec 12 19:17:12 home kernel: ums0: A4Tech PS/2+USB Mouse, rev 1.10/0.01, addr 2, iclass 3/1
Dec 12 19:17:12 home kernel: ums0: 8 buttons and Z dir.

All work fine.

Brief Specs: http://www.a4tech.com/EN/product2.asp?CID=102&SCID=103&MNO=X-750BF

Same mices on same pc works fine through ps/2 plug under Windows.

I'think it deal with wrong detection of this mices as model Generic PS/2, may be it closer to intellimouse?

Same problems of other users:
