Intercepting then modifying USB traffic

[Turkuaz]

Hello all,
I am working on a licenced prog. It is protected by license files on a memory stick, licence is related to serial number of the memory stick. Because of this it is not working if you copy licence files to another memory stick.

I wonder if it is possible to listen USB traffic, then intercept and change SerialNo in the related USB traffic. I mean to fake serial number of a memory stick.

I am working on hardware solution but software solution would be nicer.

Any idea and help welcome.

i know this maybe a little simple but i remember back in the day i had to make sure the
volume serial numbers matched on the "cloned" stick. did you do that in your test?

I wish it was so easy.
Not volume serial number. I mean hardware serial number embedded in the firmware.

I forgot to say it is .Net programme and uses System.Management class to get USB Drive info

For .net interception I'd recommend from my past experience libHarmony - https://github.com/pardeike/Harmony
