Need assistance in installing an HP Laserjet 1000 printer locally (currently have it set up to share, etc. on daughter's cpu)...we've been having issues with this for awhile now. The USB ports on our Dell Dimension 3000 (P4 2.8ghz/512mb RAM, running XP) do not work. Tried dis-abling in Device Mgr., rebooted cpu, but still nothing....tried installing in Safe Mode--nothing...tried everything that was suggested on this site, to no avail. Plug n' Play not working... Yesterday, I got a USB 2.0 PCI add-on card and installed it, thinking it would do the trick. It recognizes/works for EVERYTHING except the printer!!! what gives?? it's not just the HP, we have a Brother copy/fax/scanner that we use for scanning docs., and it is not recognized/nor can be installed either...just when it looks like install is done, we get "the specified port is unknown" error...also, when using the Install Wizard and am prompted to select the port, there are no USB ports available--only COM & Serial...??? any ideas would be greatly appreciated!!!!
