I have 8.1-RELEASE running on an Optiplex 980 with no keyboard problems, but not with a Dell keyboard as we ordered Cherry keyboards with our Dells (the person evaluating the Dells thought the keyboard was way too light and fragile). Since I usually have the keyboard plugged into the hub in the display, I just tried it directly in the (rear) usb ports with no difference. Trying the Fujitsu and Sun keyboards from the other machines in my office does not immediately lead to problems, either. (Or how much would I have to type to reproduce the problem?) Maybe it is just the keyboards? Or a bios setting? (I cannot currently reboot to check if there are any keyboard related bios settings I changed.) Based on this post, I switched my keyboard so that it runs through the hub in my monitor. It seems to have fixed the problem, as I haven't seen the keyboard repeat in almost a day. I'm still curious as to what the actual problem is. Maybe the fact that running it through a hub first will help to narrow down the issue.

For FreeBSD 8+ this is not true. Probably the manpage has not been updated. Hence you are seeing a different number of UHCI controllers, this looks like an ACPI problem. USB keyboards usually require a UHCI to enumerate. The EHCI can only enumerate High Speed devices. --HPS ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
