Details - I had to install kmod-usb3 to get usb working. I think this should be included in the default distribution.

Supply the following if possible:

 - Device problem occurs on
Netgear R6220

 - Software versions of LEDE release, packages, etc.
DISTRIB_ID='LEDE'
DISTRIB_RELEASE='SNAPSHOT'

DISTRIB_CODENAME='reboot'
DISTRIB_TARGET='ramips/mt7621'
DISTRIB_ARCH='mipsel_24kc'
DISTRIB_DESCRIPTION='LEDE Reboot SNAPSHOT r3925-64175ff'
DISTRIB_TAINTS='no-all'

 - Steps to reproduce
dmesg # notice no usb support
opkg update && opkg install kmod-usb3
dmesg # now shows usb support
