psaux mouse driver + inland pro optical 100 mouse

Under linux 2.4.1 if I move the mouse slow enough it doesn't register at all in Xwindows. If I unplug the ps2 mouse and plug it back in, it works perfectly, no matter how slowly I move it the movement is registered. It is as if the linux kernel is imposing a threshold on the movement.

Under windows it works fine. The problem is in linux.

I've tried modifying pc_keyb.c code by sending an F6 byte to set defaults, using the aux_write_ack function in open_aux(), but that doesn't have any effect. Does anyone have a clue what the driver is doing to reduce the quality of the mouse? I'm not sure it is limited to this particular mouse, it is just the one I just bought at Fry's for $10.

I'm running an athlon 1 gig, /proc/version is
Linux version 2.4.1 (root@dave) (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #17 Fri Jun 15 20:15:45 PDT 2001

Thanks!

Try commenting out the AUX_RECONNECT block on line 406 in pc_keyb.c

#ifdef CONFIG_PS2_KEYBOARD_SWITCH_COMPATIBILITY_MODE	
	else if(scancode == AUX_RECONNECT){
		queue->head = queue->tail = 0;  /* Flush input queue */
		__aux_write_ack(AUX_ENABLE_DEV);  /* ping the mouse :) */
		return;
	}

#endif

and let me know what happens..
