You do know that the routine inside thier drivers as assertained from the symbol tables in the driver code was called
"BrickClonedDevices"
I think that is a smoking gun, and shows intent.
How much chance does 99% of the population have of recovering the functionality of a bricked device, even if pid 0 is rewritable. Its like telling a comsumer that a phone that has scrambled its eeprom is still perfectly ok, all they have to
Do is buy a JTAG interface, hook it up, learn several years of embedded systems knowledge. But its not bricked is it.
For all intentive purposes it is Bricked as far as a consumer is concerned who has never heard of FTDI.
