PSA -- Rotel Firmware Update and USB Class


For anyone using a Rotel RC-1590 / RA-1592 or similar, be aware that a firmware update may set your USB class back to 1.0. Which then means there is no option to play DSD, etc.

I happened to update the firmware at the same time there was a Roon version update, and didn’t know where to look.

To check / fix, cycle through the menu button until the display shows USB class; if not at 2.0, please select as such.

Posted 1. to make me feel better, 2. to maybe save someone else 3 hours in future.
