I changed from a PS/2 mouse to a USB one. It doesn't work under X. The kernel finds it (see the dmesg output below). I am running Mandrake 8.1, Xfree 4 with an ATI Rage 128 Xpert. I modified /etc/sysconfig/usb to mouse = on with no effect, manually ran XF86Config and chose Intellimouse as the mouse type. Still nothing :( I did accept the default setting for the mouse of /dev/mouse. Should I have chosen a different location? If so, what??? usb.c: registered new driver usbdevfs usb.c: registered new driver hub usb-uhci.c: $Revision: 1.259 $ time 17:30:17 Sep 23 2001 usb-uhci.c: High bandwidth mode enabled PCI: Found IRQ 12 for device 00:04.2 PCI: Sharing IRQ 12 with 00:04.3 PCI: Sharing IRQ 12 with 00:09.0 usb-uhci.c: USB UHCI at I/O 0xb400, IRQ 12 usb-uhci.c: Detected 2 ports usb.c: new USB bus registered, assigned bus number 1 hub.c: USB hub found hub.c: 2 ports detected PCI: Found IRQ 12 for device 00:04.3 PCI: Sharing IRQ 12 with 00:04.2 PCI: Sharing IRQ 12 with 00:09.0 usb-uhci.c: USB UHCI at I/O 0xb000, IRQ 12 usb-uhci.c: Detected 2 ports usb.c: new USB bus registered, assigned bus number 2 hub.c: USB hub found hub.c: 2 ports detected usb-uhci.c: v1.251:USB Universal Host Controller Interface driver mice: PS/2 mouse device common for all mice hub.c: USB new device connect on bus1/2, assigned device number 2 usb.c: USB device 2 (vend/prod 0x45e/0x1e) is not claimed by any active driver. usb.c: registered new driver usb_mouse usb-uhci.c: interrupt, status 3, frame# 1596 input0: Microsoft Microsoft IntelliMouse® Explorer on usb1:2.0 usbmouse.c: v1.6:USB HID Boot Protocol mouse driver usb.c: registered new driver hiddev usb.c: registered new driver hid Thanks, James Spinti jspinti at dartdist.com 952-368-3278 x396 fax 952-368-3255
