Jeff,
I hope to use a similar product, the TAS1020a in an upcoming project. Could you please post a link to the sample code that you found for your tusb chip. I would like to use that as a basis to start with mine.

The TAS1020a appears to be aimed more at the audio market. Notice the 'AS' for audio instead of the 'usb' naming convention. Unfortunately it only has the one STDOUT, and 2 STDINs. I'd rather have the 3 STDOUTs like on the TUSB3200, but what I do like is the TAS chip's ability to do a host download instead of an EEPROM download. Cool? We'll see.

Thanks a bunch,
-Mike
