Didnt check the version number as it is such an uncommon request here. Someone should have one unless the ver 2.1 is brand new or something else odd.
hmm quick spot check indidcates the ver 2.1 might be why you are asking as version is usually not show or mentioned in advertisement. So, sorry about that. There are likely some out there but finding that exact one. You sure you are not thinking about the driver which is currently version 2.1 ? Latest I could find on chip is version 1.2.
Anywho, not my cup of tea maybe someone else can help more. Luck.
