My past FDTI deployments have become ticking time bombs to me. Can they survive the next FDTI update? and what new compatibles are FDTI going to find? and what new intrusive measures are they going to introduce? I paid good money for FDTI cables but I can never be sure what did I get. If I got unlucky and got hit, and my client knew they were "not genuine", then my brand and reputation shall go down the drain with the FDTI.
Don't you see? If those devices used counterfeit chips, then they were
ALREADY ticking time bombs. You were screwed from the moment the distributor threw a reel of counterfeit chips in a box and slapped a label with your address on it (or your build house's address, or the build house who assembled the product you bought). It doesn't matter what FTDI does or doesn't do, those devices are already ticking time bombs because they use POS counterfeit chips with unknown specs, zero R&D, and zero QC.
Why are you not as concerned with
other counterfeit chips making their way into your product? What about a counterfeit linear regulator with specs so far out of wack that the output ripple ends up destroying half the devices down the line? Or shorts Vin to Vout as soon as the ambient temp passes 30 C, blowing up everything on the board?
Personally, I'd much rather the driver tell me what's wrong, than spend weeks/months hunting down an interface that randomly corrupts bytes or drops packets whenever the humidity is above 80% on a Thursday.
FTDI has to put something in their driver to stop communication and tell you what's wrong. Not doing so would just be sweeping the problem under the rug, ruining their reputation, manufacturers' reputations, and allowing the problem to get even worse.
Now WHAT they do is certainly up for debate. For ME and MY APPLICATIONS, it makes absolutely no difference if they simply won't talk to the chip, brick the chip, or change the output of the chip to read "NOT GENUINE". No matter what they choose, the device is going back to the manufacturer (or if this is my device, it's going back to the build house, or if I built it myself, I'm getting on the phone immediately with Digikey/Mouser). It really doesn't make a difference.
