USB Scope can snoop, compare and modify USB traffic which can assist both commercial and open source development of drivers and diagnosis of issues. Other ideas will be examined such as a USB-TCP/IP-USB proxy to remotely connect USB devices. Open or free software equivalents exist, but hardware monitoring devices only exist as expensive commercial products.
Abandoned, see the USB-Sniffer project instead, which was completed.
