Yes. I am working with two boards, one based on MT7621 and the other on MT7623, and I would like to connect two EP06-modems to these boards. However, the USB-controller used on these SoCs has a (very) limited number of USB endpoints. With the default configuration, there are only enough endpoints for one EP06-modem to work properly. By disabling diag, there are enough endpoints for both modems to work correctly. BR, Kristian
