# Analyze Bluetooth protocols on Windows using Wireshark

Wireshark for Windows comes with the optional USBPcap package that can be used to capture USB traffic. Most computers with Bluetooth, internally use the USB bus, or you can use an off-the-shelf USB dongle. To capture USB traffic, start capture on the USBPcap1 interface or something similar. You can determine if any Bluetooth traffic has been captured, by entering bluetooth in the filter box. Other useful filter terms are hci_usb, bthci_acl, btl2cap, btrfcomm, and btspp.
