This does not happen all the time. Microsoft acknowledges that if a USB device is
inserted and remove a few times quickly the port can freeze and not respond to any
devices plugged it to it.
1. use device manager menu option of USB controllers to "scan for changes"
2. reboot the computer
I have found only "reboot the computer" option to solve the problem.
My question is how can I reset or cause XP to do what ever it does on boot up to
get the USB port working again without having to reboot?
This situation happens while I am in a development mode working with sensitive
USB devices that have a tendency to detach and reattach quickly when certain
loading happens on that port. ( suspect USB power issues) As I am debugging it is
a pain to have to reboot every time this happens.
