I am thinking of using element14's BBB (http://my.element14.com/element14/bbone-black-4g/beaglebone-black-rev-c-cortex/dp/2422228 ) with USBProxy (https://github.com/dominicgs/USBProxy).
However, the USBProxy project is pretty out of date, and I don't know if the minor hardware mods on the element14's board is actually compatible. The main functionality of USBProxy is to relay USB data between the USB Host and USB Device ports on the BBB. This allows me to sniff the data in the process.
Any advice is appreciated.
