For bluetootu connection in xamarin forms, you can try to use following nuget package to achieve it.

For demo or blog about BLE, you can Google: Integrate and use the BLE Plugin for Xamarin by Rebai Hamida

For USB connection, I cannot found Forms plugin to achieve it, but you can achieve it with dependence service for different platforms.

Sample code :
adapter.ScanExtra().Subscribe(scans => {
adapter.StopScan();
scanResults = scans;

scanResults.Device.ConnectWait(); });
