I have noticed two things, and I can't explain why those design decisions were made. 1. Port USB0 is different from USB1 - therefore a printer installed on USB0 is not installed on USB1. If the printer gets switched from USB0 to USB1, it is no longer installed/connected for use. 2. Occasionally Windows will think that the order of USB ports is different from before. Not sure why. This leads to issues related to 1, above. 1 will also happen if something is unplugged from one physical port and plugged into another physical USB port. -- John DeCarlo, My Views Are My Own ************************************************************************ * ==> QUICK LIST-COMMAND REFERENCE - Put the following commands in <== * ==> the body of an email & send 'em to: [EMAIL PROTECTED] <== * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?
