My Dev device flashes a fast red when in the Custom mode, and a fast green when in the Default mode, when hooked up to the USB port on the computer. The Dev Datasheet does not say anything about LED status. I have flashed the device with the USB Mic app only.

Fixed.
The state of the LED is determined by the firmware running so this isn't described in the datasheet. The AudioMoth USB Microphone firmware is described on the webpage here:
https://www.openacousticdevices.info/usb-microphone There are more technical details in the following two application notes: https://github.com/OpenAcousticDevices/Application-Notes/blob/master/Using_the_AudioMoth_USB_Microphone_Firmware_and_Hardware/Using_the_AudioMoth_USB_Microphone_Firmware_and_Hardware.pdf https://github.com/OpenAcousticDevices/Application-Notes/blob/master/Configuring_the_AudioMoth_USB_Microphone_from_the_Command_Line/Configuring_the_AudioMoth_USB_Microphone_from_the_Command_Line.pdf The colour of the LED tells you whether the switch is in CUSTOM or DEFAULT. In DEFAULT, just the configured gain and sample rate are applied, in CUSTOM any additional advanced settings and filters are also applied. If you haven't changed the default settings the effect is the same in either switch position:
USB/OFF: When the switch is set to USB/OFF the sample rates, gain and filter options can be set through the AudioMoth USB Microphone App above. The green LED will light when USB is connected.
DEFAULT: When the switch is set to DEFAULT the device will enumerate as a USB microphone implementing the set sample rate and gain. The green LED will flash at a rate determined by the sample rate (identical to that of the standard AudioMoth firmware).
CUSTOM: When the switch is set to CUSTOM the device will again enumerate as a USB microphone implementing the sample rate and gain settings as above, and also the requested filter and advanced settings. The red LED will flash at a rate determined by the sample rate (identical to that of the standard AudioMoth firmware). You can switch between DEFAULT and CUSTOM whilst recording to see the effect of these settings.
