awus036h and maybe others keep connection logs within the adapter, if it was ever confiscated by an authority person thinking you where doing something illegal they could pull out the logs from the wifi device itself, no need for the computer it was used on.
I used this adapter on my laptop to connect to my own wifi, my friend came over with his laptop and I hooked it up to his laptop, guess what? it connected to my wifi without even entering my password...
hmm ... if anyone can confirm alfa adapters keep logs within the adapter itself please let me know..
