USB didn't work on HG255D

I installed kmod-usb-core and other modules.
but lsusb still returned
unable to initialize libusb: -99

Did you format the device? are you sure your device is supported by your router? do you know what type of usb capabilities your device has?

you sure you didn't stick it in the wrong port lol sorry had to make some comedy out of it! "thats what she said"

Which LEDE version and which "other modules"?

I'm sorry for giving such few information about it.
LEDE version is 17.01.4.
kmod-usb-core kmod-usb-uhci kmod-usb-ohci kmod-usb-storage
kmod-ath9k-common kmod-ath9k-htc kmod-ath
is installed
my wireless adapter(ar9271) and flash disk didn't work.
They could work with these modules on Openwrt 15.05.1

opkg install kmod-usb-dwc2
