I’m looking for device that will allow to connect my Bluetooth keyboard to any computer – it should be like a bridge between keyboard and send keyboard keys via USB so no driver is needed. On receiver side it should be tread like normal USB keyboard. I need this for sharing my keyboard via KVM to connected PC’s. Is there any device like that on the market?
