Support for QCA9377-7 (WIFI-BT usb combo)

Hi guys,

I'm building a custom router and I'm looking for a chipset for the wifi. I'm testing the QCA9377-7 with is a wifi to usb interface, but OpenWRT doesn't seems to support it even if the backport support it.

When I modify the .config of the backport to add support for the Ath10k-usb, the make of the openwrt is overwritting the .config of the backport and remove the option.

Is there anyone who know how to change the backport config so the openwrt won't erase it?

I'm not close to suggestion on a better usb to wifi chipset if any.

Thanks

William
