There are three internal USB devices: Bluetooth, a Sierra CDMA modem thingy and a fingerprint reader. $ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 005 Device 003: ID 0483:2016 SGS Thomson Microelectronics Fingerprint Reader Bus 005 Device 002: ID 0a5c:2110 Broadcom Corp.
