From time to time, the kernel thinks it was disconnected and then reconnected again, altough nobody touched the cables. It would be OK, but there is a problem: after the reconnect, it become active as /dev/input/mouse1 instead of /dev/input/mouse0, and my X server cannot (of course) find it. The system is RH7.2, kernel 2.4.16, Athlon 850 (ABIT KT7). Here is the dmesg output of the USB after boot: usb.c: registered new driver usbdevfs usb.c: registered new driver hub usb-uhci.c: $Revision: 1.268 $ time 19:53:08 Dec 5 2001 usb-uhci.c: High bandwidth mode enabled PCI: Found IRQ 10 for device 00:07.2 PCI: Sharing IRQ 10 with 00:07.3 PCI: Sharing IRQ 10 with 00:0b.0 usb-uhci.c: USB UHCI at I/O 0xd400, IRQ 10 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 10 for device 00:07.3 PCI: Sharing IRQ 10 with 00:07.2 PCI: Sharing IRQ 10 with 00:0b.0 usb-uhci.c: USB UHCI at I/O 0xd800, IRQ 10 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: v1.268:USB Universal Host Controller Interface driver usb.c: registered new driver hid hid-core.c: v1.8 Andreas Gal, Vojtech Pavlik hid-core.c: USB HID support drivers mice: PS/2 mouse device common for all mice hub.c: USB new device connect on bus2/1, assigned device number 2 input0: USB HID v1.00 Mouse [KYE Systems Genius USB Wheel Mouse ] on usb2:2.0 hub.c: USB new device connect on bus2/2, assigned device number 3 input1: USB HID v1.10 Keyboard [Chicony USB Keyboard] on usb2:3.0 And the disconnect/reconnect looks like this: usb.c: USB disconnect on device 2 hub.c: USB new device connect on bus2/1, assigned device number 4 input0: USB HID v1.00 Mouse [KYE Systems Genius USB Wheel Mouse ] on usb2:4.0 Where the disconnect/reconnect come from, and why the mouse changes its device number? -Yenya -- | Jan "Yenya" Kasprzak | | GPG: ID 1024/D3498839 Fingerprint 0D99A7FB206605D7 8B35FCDE05B18A5E | | http://www.fi.muni.cz/~kas/ Czech Linux Homepage: http://www.linux.cz/ | Having your own personal custom language dialect might be tempting but it is normally something only the lisp community do.
