Synaptics probe problem on Acer Travelmate 3004WTMi

[Thomas Sailer <sailer@sailer.dynip.lugs.ch>]

Hi Vojtech,

I've got a problem with my Acer Travelmate 3004WTMi Laptop: vanilla 2.6
does not detect the synaptics touchpad.

The problem lies within psmouse_probe: after the PSMOUSE_CMD_GETID
command, param[0] contains 0xfa, and not one of the expected values. If
I just ignore this and continue, the synaptics pad is detected and
everything works ok.

static int psmouse_probe(struct psmouse *psmouse)
 642 {
 643         struct ps2dev *ps2dev = &psmouse->ps2dev;
 644         unsigned char param[2];
 645 
 646 /*
 647  * First, we check if it's a mouse. It should send 0x00 or 0x03
 648  * in case of an IntelliMouse in 4-byte mode or 0x04 for IM
Explorer.
 649  * Sunrex K8561 IR Keyboard/Mouse reports 0xff on second and
subsequent

 653         param[0] = 0xa5;
 654         if (ps2_command(ps2dev, param, PSMOUSE_CMD_GETID))
 655                 return -1;
 656 
 657         if (param[0] != 0x00 && param[0] != 0x03 &&
 658             param[0] != 0x04 && param[0] != 0xff)
 659                 return -1;
