USB Port with USB Modem - error can't open Port when querying mod
'Windows XP Profession, sp2 sees the modem. Modem is US Robotics Model 5633.
It shows up in the Device Manager but when I query it under the diagnostics I get the error "Cannot open Port". Port does not show as in use. Same port sees a usb hard drive and reads it fine. Same modem installs and works fine at another computer. Any suggestions? Thanks |
