Well for Bluetooth to start you have to run systemctl start bluetooth
and then systemctl enable bluetooth
to start the Bluetooth service at every boot. For some reason the systemd Bluetooth service is not enabled by default in debian.
I unfortunately have no idea of how to resolve your USB issue.
Also coming from one noob to another - don't reinstall or restart to fix issues. Always make a good faith effort to search online for ways to fix your issues. Not only will this approach be more effective in solving the issue, you will also end up learning some new things.
Edit : Actually I might be mixing up debian and arch. https://wiki.debian.org/BluetoothUser ←refer to this for Bluetooth related issues
