Hi! You can execute
dmesg | grep tty in order to get information on the serial ports. You'll find lines like [...] 481a8000.serial: *ttyS4* at MMIO 0x481a8000 (irq = 187, base_baud = 3000000) is a 8250 which informs about the port used for a connection, ie. when you plug in the Teensy device. Keep in mind, you cannot power heavy load on the USB port when the BBB is powered by USB. You'll need an external power supply (at least 5V/1A).
