I have a product we have been making for a few years now that we developed with Teensy. Has been working great, but now we somehow got an old batch of chips. This old batch of chips seems to only work if I compile in teensy with USB disabled. If I turn USB off, then I can get code to run, otherwise it hangs up on power up. I suspect it's from the chip maker errata. I do not know if anything can be done, but any ideas could help. All of our bins of past have been 2N36B or 3N36B.

In the meantime, I have over 2000 units of a product that need chips removed and replaced with a newer bin, and just lost a ton of money...
