[Disclaimer: I am new to the list so I don't know if this has been addressed before or not, but I couldn't find the problem listed in the archives.]
I have a MS Natural KB Pro and a MS Intellimouse Explorer (the one with the red light underneath). Periodically (usually every 2 days, sometimes more/less), my keyboard and mouse both simultaneously stop working. The red light goes out on the mouse, and Caps Lock doesn't toggle the light on the keyboard. The keyboard and mouse are both plugged into their own separate USB sockets in my machine. I am running RH7.3 with kernel 2.4.18 on an Asus A7M-266 / Athlon 1.4GHz system. I experienced the same problem with RH7.2 on the same machine, so it is not just the kernel version I am using. I have tried using other USB sockets, without effect. Here is some output from /var/log/messages from when the problem occurred: ---------- Jun 22 14:09:23 lukeh kernel: usb.c: USB disconnect on device 2 Jun 22 14:09:23 lukeh kernel: hub.c: USB new device connect on bus2/1, assigned device number 5 Jun 22 14:09:27 lukeh kernel: usb_control/bulk_msg: timeout Jun 22 14:09:27 lukeh kernel: usb.c: USB device not accepting new address=5 (error=-110) Jun 22 14:09:28 lukeh kernel: hub.c: USB new device connect on bus2/1, assigned device number 6 Jun 22 14:09:32 lukeh kernel: usb_control/bulk_msg: timeout Jun 22 14:09:32 lukeh kernel: usb.c: USB device not accepting new address=6 (error=-110) ---------- The way to fix the problem is to simply log in remotely and do: rmmod usb-uhci && insmod usb-uhci which gives the following: ---------- Jun 21 20:04:25 lukeh kernel: usb-uhci.c: $Revision: 1.275 $ time 15:54:37 Jun 10 2002 Jun 21 20:04:25 lukeh kernel: usb-uhci.c: High bandwidth mode enabled Jun 21 20:04:25 lukeh kernel: PCI: Found IRQ 5 for device 00:04.2 Jun 21 20:04:25 lukeh kernel: PCI: Sharing IRQ 5 with 00:04.3 Jun 21 20:04:25 lukeh kernel: PCI: Sharing IRQ 5 with 00:09.0 Jun 21 20:04:25 lukeh kernel: usb-uhci.c: USB UHCI at I/O 0xd400, IRQ 5 Jun 21 20:04:25 lukeh kernel: usb-uhci.c: Detected 2 ports Jun 21 20:04:25 lukeh kernel: usb.c: new USB bus registered, assigned bus number 1 Jun 21 20:04:25 lukeh kernel: hub.c: USB hub found Jun 21 20:04:25 lukeh kernel: hub.c: 2 ports detected Jun 21 20:04:25 lukeh kernel: PCI: Found IRQ 5 for device 00:04.3 Jun 21 20:04:25 lukeh kernel: PCI: Sharing IRQ 5 with 00:04.2 Jun 21 20:04:25 lukeh kernel: PCI: Sharing IRQ 5 with 00:09.0 Jun 21 20:04:25 lukeh kernel: usb-uhci.c: USB UHCI at I/O 0xd000, IRQ 5 Jun 21 20:04:25 lukeh kernel: usb-uhci.c: Detected 2 ports Jun 21 20:04:25 lukeh kernel: usb.c: new USB bus registered, assigned bus number 2 Jun 21 20:04:25 lukeh kernel: hub.c: USB hub found Jun 21 20:04:25 lukeh kernel: hub.c: 2 ports detected Jun 21 20:04:25 lukeh kernel: usb-uhci.c: v1.275:USB Universal Host Controller Interface driver Jun 21 20:04:26 lukeh kernel: hub.c: USB new device connect on bus1/1, assigned device number 2 Jun 21 20:04:26 lukeh kernel: printer.c: Disabling reads from problem bidirectional printer on usblp0 Jun 21 20:04:26 lukeh kernel: printer.c: usblp0: USB Unidirectional printer dev 2 if 0 alt 1 proto 2 vid 0x03F0 pid 0x0604 Jun 21 20:04:26 lukeh kernel: hub.c: USB new device connect on bus2/1, assigned device number 2 ---------- It tends to occur more frequently during or after periods of heavy processor/HDD activity. The problem has been happening for a long time, and is very frustrating. The problem happens very quickly if I plug the mouse into the USB hub on the keyboard, but then again, I have had many, many problems running devices out of those MS Nat KB Pro hubs, in both Windows and Linux, so I think that the MS hub hardware/firmware is very flaky. The only reference to the problem having been experienced by anyone else that I can find using Google is on the following page: http://www.linuxgazette.com/issue76/tag/4.html (I can understand it having been experienced by other people who have just thought they had an X/kernel crash, since unless something is happening on your screen, everything seems to indicate a hard lockup; however the remote rmmod/insmod trick fixes the problem every time.) What other diagnostics can I run to find the source of the problem? I am tempted to buy a USB->PS/2 adapter for both the mouse and the keyboard, but I would like to get this fixed so that other people don't have the same problem. Thanks, Luke Hutchison. P.S. A separate question: What would be causing the message "Disabling reads from problem bidirectional printer on usblp0" in the second of the two log sections above? I have an HPDJ-842C. Is it likely to be a related USB problem, or is it a problem with the printer's USB support, or is it an indication that bidirectional USB printer support in Linux is not fully implemented? I can print fine -- what do I lose by not getting bidi support when communicating with my printer? I'm not aware of any way in which the Linux printing system uses the feedback from the printer the way that Windows does. ------------------------------------------------------- Sponsored by: ThinkGeek at http://www.ThinkGeek.com/ _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
