Any news on this? http://community.onion.io/topic/2246/cannot-satisfy-dependencies-for-kmod-usb-net-rndis
It is still not possible to install rndis

I am also interested in installing rndis.
In the repository there are older versions of the kernel modules for the current kernel but they didn't work for me yet, some of them loaded correctly but something always fails so far. You can try to install them with - -
force-depends.
I also tried to compile my own firmware but since that is just lede without the onion customizations this is not really what I want to use.
Maybe the current packages where built for the firmware version 163? It seems that there where 161-163 versions available but they where very unstable. Maybe they deleted them but the compiled packages staid in their repository?

If I have more time I will try again to get the older packages from the repositories working. You can open the onion core repository in a browser to see the different versions from the packages and then search for them with ctrl+f. The installated opkg version doesn't seem to support installing different versions.
As a hint: opkg install with url did also not work for me, Wget + opkg install package.ipk did work and most modules even loaded. I got the virtual CD drive listed in dmesg after installing some kernel modules which wasn't the case before but I didn't get rndis to work.

I even tried to upgrade everything including the kernel but that resulted in more Lede stuff, the onion repositories where replaced by Lede repositories and the banner also was the Lede one (I only used omega repositories). I also got even more depency errors. The Kernel didn't seem to be upgradable since it stayed at the old version.
