FTDI refusing to let their device drivers operate with a fake device is the best resolution for this situation.
Most buyers have to trust their suppliers when ordering small quantities. Those suppliers also have to trust their brokers / wholesalers too. How on earth are small scale customers supposed to ensure that their device is kosher?
FTDI have authorities that can help them stem the flow of these fakes in the UK at least (Trading Standards and Customs & Excise.) They should be using those instead of bricking an innocent third parties components.
