Is it on the list in the first post? If not, then it's no surprise it doesn't work because there wasn't certainty that it would. Your only choice is to either get a different controller/adapter, or try to pm one of the devs to see if you can get some help which is hard because they'll either need to have the same adapter, or ask you to give as much info as you can about it to help pinpoint the issue; so you'll have to be patient if you go this route.. Howard is the one who's spent most time dealing with controller issues, so maybe he can help you; not sure how often he gets online though.
