All these problems have more or less the same cause: The keyboard fails to respond to packets sent by the computer. Presumably because the KVM hub is failing to relay them, although it also could be a result of poor-quality USB cables or a bad connection. > I read the docs on usbmon and captured the listing below after booting > with a usb keyboard plugged directly into the computer, determining the > usb port and then after starting usb capturing, I unplugged the keyboard > and plugged the iogear hub in.

Those errors mean the same thing as I wrote above: The keyboard has failed to respond to a packet sent by the computer. > I hate to lose the use of FC6, but I don't have room on my desk for two > keyboards and mice. Where can I go from here? Try using a different USB port on your computer. Try using different USB cables. Try using a different KVM switch (although all USB KVMs seem to be problematical to some extent). Alan Stern ------------------------------------------------------------------------- Take Surveys.
