USBblaster does not show up in Quartus

Sometimes firefox happens to open port 1309 by chance and blocks jtagserver. Try `netstat -an | grep 1309` to see if anything is listening on that port.

jtagserver needs administrative access to register with the service manager but once you've registered a normal user can start it. All the jtag programs (programmer, SystemConsole etc) will start jtagserver if it is installed but not running.

The exception is if you have quartus installed on a network in which case the service manager will need a username and password to access the jtagserver binaries.
