[CGUYS] USB Malfunction
Can anyone tell me why on a Windows XP machine with a scanner, printer, and multi-card reader all on USB the printer loses connectivity from time to time? Also I noticed in Device Manager there are 4 USB controller though there are 6 USB ports.

Also I noticed in Device Manager there are 4 USB controller though there are 6 USB ports. What is the relation? 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?

Re: [CGUYS] USB Malfunction
This seems to be generally true. I've seen this on every computer I have, admittedly all Windows 2000. I suspect that each piece of USB hardware (controller, hub, etc, as well as peripheral) has a unique hardware address, similar to the MAC address that Ethernet adapters and other networking hardware have. If something auto-installs, then it will re-install automatically when plugged into a different USB port, and the installation may be transparent (invisible to the user). If the printer requires manual installation (selection of the printer make/model from a list), then it must be manually reinstalled if you change the USB port that it is connected to. If you disconnect something that doesn't auto-install, be sure to plug it back into the same port. Fred Holmes At 11:09 AM 1/28/2008, John DeCarlo wrote: 1.
