Hello all, I hope this is in the correct location.
I have noticed recently that if I unplug my USB keyboard and then plug it back in the computer can not detect it. As in ANY keyboard will no longer be detected. Keyboard lights up, function within the keyboard like LEDs can be controlled, it simply has no input over the computer. Restart the system and keyboard functions as normal.
To me it is as thought the keyboard is acting as a PS/2 and not a USB in that the PC must be restarted.
I have tested this in different USB ports, different keyboards, etc. I even used a trackpad/keyboard combo and the mouse portion worked on plugging the device in, but the keyboard did not. (This makes me think it is how windows is interpreting the signals and not a hardware thing as the mouse pad portion on the same device functioned fine.)
This is only limited to keyboard input. I have all USB ports set to do not power off, drivers have been uninstalled and reinstalled, power mode does not turn USB ports/devices off, etc.
Any advice? ( I know the simple answer is not to unplug the keyboard, but this does happen sometimes and restarting is frustrating.)
System is a custom build Windows 7 64bit machine and this keyboard/PC combo has been proven for approximately a year prior to this starting.
TL;DR: All keyboard function is suspended until restart if accidentally unplugged.
