ModemManager-devel Digest, Vol 64, Issue 19

Mon Oct 1 12:31:53 UTC 2018

I bought this a while ago from ebay. I think it is fully supported. the
model is ZYX-WF05-R6. weird thing is I can manually enable adapter by doing
those 3 commands. I alsoo remember during the openwrt compile process.
There are some warnings about missing  dependency. Here is the message.
Thanks again for your help
