hi all, here's my problem: I've got a usb mouse, with I use on an Dell inspiron 5100 laptop. Everything works fine on windows, that is I can plug in and out the mouse, and it is working. So there's apparently no hardware problem.
When I boot on linux, with the mouse plugged in, it is powered (optical light is on), and perfectly detected by the host controller. When I plug out the mouse, I see the standard message: usb.c: USB disconnect on device 00:1d.1-1 address 2 However, when I plug the mouse again in the usb slot, there is no kernel message displayed, and the mouse is not powered (no optical light on). the hardware is a standard Inter host controller: 00:1d.0 USB Controller: Intel Corp. 82801DB USB (Hub #1) (rev 02) 00:1d.1 USB Controller: Intel Corp. 82801DB USB (Hub #2) (rev 02) 00:1d.7 USB Controller: Intel Corp. 82801DB USB EHCI Controller (rev 02) I am using usb from 2.4.21-rc5. I tried both usb-uhci, and ehci-hcd, and the result is the same. I also tried 2.4.20 with gentoo (usb-uhci). I've got a desktop with the same hardware (except rev is 01), and it works fine (powers the device again when reconnected). Thanks if anyone can give me some infos how to solve this. PS: i am not sure if it is related, but I saw a particular behaviour: when there is no usb modules loaded in the kernel, and I open the /dev/psaux touch pad device, it recieves events from the connected usb mouse ! As soon as I load the host controller, usb mouse is not connected to ps/2 port anymore. I was wondering how they managed to do this, if there was a hardware circuit bridging usb to the ps/2 port, or if the bios had set some interrupt handlers in the host controller to forward mouse movements to the touch pad. ------------------------------------------------------- This SF.net email is sponsored by: Etnus, makers of TotalView, The best thread debugger on the planet.
