Hello,
I was trying to install a Linux based OS from a thumb drive and I received a message saying that USB security was preventing the install. My PC is a HP Pavilion All in One 24-b010 with a Samui A9 Motherboard. I went into the bios and I disabled security for the USB connections in the BIOS. I was expecting this to allow me to install an OS from an unknown source or something but instead it just deactivated all the USB connections. I can now no longer use any USB devices so I can't do anything with the computer. No keyboard or mouse will work with it.
I have tried resetting CMOS by placing the only jumper pin on the motherboard (right of the motherboard battery) with no luck. I have taken the battery out and left the computer idle for over 30 minutes with no luck. I have held down the power button while the computer was unplugged and the motherboard battery was taken out for over 30 seconds with no luck.
When I restart the computer after resetting CMOS the BIOS acknowledges that CMOS has been restarted but the USB connections still do not work. I have tried multiple keyboards. Anybody have any other ideas I could try? I really don't want to buy a replacement motherboard because of a BIOS issue.

Ok I solved it by moving the jumpers on the motherboard. There are ten pins with five on top and five on bottom. The default jumper position is on the two most right pins on the top. To reset CMOS successfully I placed the jumper vertically on the seconds pins (pin #2 and the one directly under it pin # 7).
