I know I would be glad to rat out the counterfeiters because I don't want counterfeit chips in my gadgets. If they were to ask me I would give them the information on where I got the gadget so FTDI could either help the manufacturer fix their supply chain, or follow it to the actual culprit.
Punishing the end user is passive aggressive. They know their gadget is broken, but not why it is broken. Frankly I hope they become the subject of a class action. They have no right to destroy hardware.
I have had no issues tethering my GS4, my only streaming issues are sites that use silverlight, and plenty of steam games for fun.
Oh and BTW it looks like your complains about the Fuji(tsu)? scanner and Wacom tablet are overblown. It looks like there is some support for both, although it is not handled by the manufacturers. Both manufacturers linked to these sites so I am assuming they should be at least partially functional.
Note: I cannot even find a Fuji scanner, so I am guessing you dont even know what hardware you are using, which might explain your difficulty in installing the hardware.
