Lantiq xrx200 tplink 8970 openwrt 18.06-rc1 usb adapter

hi everyone, i have a tplink 8970 working great with lede 17.01.4, but last night i update to 18.06-rc1.
like 17.01.4 i installed the kmod ath9k_htc usb driver but is not working. also going back to lede 17.01.4 was not so easy, flashing from web interface was not possible, so i forced the flash via ssh.

hi, i still cannot make this work in the last openwrt! there is any way to make it work,please?

kmodloader: done loading kernel modules from /etc/modules.d/*
