Suddenly my only USB port is not working and working flash drives on other PC's are not read by my Spectre Laptop. Device manager (in show hidden devices) did not have COM /LPT ports listed. I got it back with install Legacy hardware but "HP Communications Port (COM3)" came back with the "!" mark in a yellow triangle. Rick clicking on it > Properties states this:
"This device cannot find enough free resources that it can use. (Code 12)
If you want to use this device, you will need to disable one of the other devices on this system."
I did get a windows update a few days before this problem was noticed. When I go to HP support and it goes through my scan for my PC it comes back all updates are current - same thing for windows updates.
Uninstalling under Device manager and reboot does not fix it.
I do not have a restore point earlier than this problem was discovered.
Thanks in advance,
Badjer
