Dear Florian Fainelli, I'm trying to enable USB drive on my Netgear R6300v2 router, and got one issue I described in https://forum.openwrt.org/t/usb2-usb3-on-netgear-r6300v2-doesn-t-detect-any-devices/108385/15. Rafal Milecki, who is from openwrt community and also CC in the email, suggests that I consult you and see if you or someone can provide one kernel patch modifying bcm4708-netgear-r6300-v2.dts, then he can backport to OpenWrt. Sorry if the request is too much, please let me know if you need any more information, or I need to consult other people for help! Thanks for your attention! Best regards Dweb
