It reminds me of something that happened to Dave and he did a video of Fairchild Semiconductors FTDI bricking a lot of suspected counterfeit chips through the driver updates in video EEVblog #676 - RANT: FTDI Bricking Counterfeit Chips!

Edit: Oops I confused the two manufacturers.

Fairchild and FTDI have nothing to do with each other.

suspected counterfeit chips
Through the method they were bricked, its impossible to brick genuine chip. They simply wrote to EEPROM with a width that the real devices ignore. So bricked chips were 100% counterfeit.

Why would Dave want to make a video on fake chips? Several people on YouTube have seriously researched the topic and made reasonable videos. I'm not aware of Dave having any specific expertise on the topic. A lot of the interesting experience many of us have with fake chips are things we can't really talk about, because companies don't want publicity about the problems they have had.

I agree with coppice, Dave does not seem to be involved in lots of projects and ordering large number of chips from China to encounter fake ones to make a video.  He just does mailbag and teardown stuff... and a couple of custom products.

Actually, the counterfeit chips were not really bricked. They were just temporary put out of service. The problem can be corrected by writing the correct values to the eeprom in the chip.
The term bricked is used when a device is damaged or rendered inoperative beyond repair.

Fixed that for you as unbricking is a thing :)

Although I agree there are already several Youtube videos dealing with counterfeit components, I really enjoy Dave's way of explaining things.
Very much, I should add.

Such that if he decides to do a video on the subject, I would definitively watch it.
