LED Warning On CC2530 / CC2591 USB Devices

[danieledwardgeorgehitchcock]

A fix that I believe was introduced in commit 3855695 to (en/dis)able the onbard LED seems to be conflicting with USB CC2530 / CC2591 devices that use the CP2102 UART to USB chip. I don't believe these devices have LED's mapped to the same pins as the other CC devices.

See below debug logs:
