Hello all!

 

I have a NanoPC-T4 and I'm currently using Android 8.1. I suppose I could flash Ubuntu to try this, but before that, here goes. 

 

I'm trying to use a USB 4G dongle with it. I get no recognition of the device. No RNDIS or any notification at all. Fresh install. Any ideas?

 

Also, has anyone tried to come up with a method of root for android on this device? It's a super cool sbc!

 

Thanks!

It depends which? Probably support is missing in the kernel but with Android you are on your own. With Armbian ... you can rebuild a kernel or just tell what to enable:

Stock 4.4.y https://github.com/armbian/build/blob/master/config/kernel/linux-rk3399-default.config

Modern 4.19.y  https://github.com/armbian/build/blob/master/config/kernel/linux-rockchip64-dev.config

 

and it's enabled in the next version.

Check usb_modeswitch - many USB 3G/4G dongles initialize as a mass storage device (check lsusb and dmesg)... they do that for Windows and sometimes Mac for users to install the carrier's connection manager software and drivers for the dongle.

Each dongle is a bit different - some support serial over USB only, some provide an ethernet interface once the mode is switched over...
