Most likely the problem lies in your host-to-host cable. But if rebooting the computer always fixes the problem, then it's in the computer. It could be a problem with the USB hardware or one of the drivers. There's no way to tell at present. Your best approach is to upgrade to 2.6.14. If that doesn't help, try using the cable on a different computer. Alan Stern ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
