-config CARL9170FW_USB_UP_STREAM
- def_bool y
- prompt "USB Upload Stream"
- ---help---
- This features allows the USB silicon to combine small, single
- frames into bigger transfers. This can help to reduce
- some per-transfer overhead in the application.
-
- Say Y, unless you have experienced strange rx corruptions.

- prompt "Pass debug messages through USB transport"
- ---help---
- Report all firmware messages through the USB transport.
- But there is a catch: In case of a BUG, the USB transport
- needs to be functional, otherwise the application won't
- receive anything.
