I'm trying to get USB Ethernet support on my tablet, which for some reason is apparently disabled even though 4.1.2 directly supports it. (My Note II can use it...) I've come to the conclusion that I'm going to need to essentially write everything on my own. I'd prefer to write an app that can be used by other 10.1 users, but right now I'm just trying to get it working at all on my own device. (I'm using a BobJ Ethernet->USB Adapter) Here are my current setbacks:
- USB Host seems to shut down randomly. This is the most irritating part, because it means I have to restart the device to use USB at all, mass storage included. What should I use to diagnose this? I've tried three different USB-specific apps from Play, but none of them give me much information besides the obvious. (That the host is not working.)
- Even when the host controller is running and can detect the adapter, 'netcfg eth0 dhcp/up' doesn't work, claiming no device detected. Does this mean the adapter driver is missing completely?
