Comment:
Stock install leaves only 176KiB free for loading packages which doesn't seem to be enough to enable USB storage support. This unit is also eqaul to tl-wr841v8 but with USB. The 841v8 version can be flashed via sysupgrade -F. So u can have support up to 18.06.x (and 21.02.x via communitiy support))
