Support for Android RNDIS / Tethering USB nics #5

Open hh opened 9 years ago

hh commented 9 years ago

It would be interesting to ipxe boot to RNDIS Android tethering nics... Combined with something like DroidDrive (to export an ISO as an emulated CDROM device to boot ipxe) you could some interesting things, possibly even emulating a keyboard to get the bios to boot to the usb/cdrom that contains pxe and using caching/squid to speed up network deploys.

I've now started working on getting usb hid gadget on top of usb RNDIS support with the Intel Edison.

When I plug it into a computer and power it up the Edison shows up as a usb HID keyboard, RNDIS nic, and mass storage device. The HID sends the sequence of keys to boot from the USB mass storage, which it turn boots iPxe w/ USB network support which could do all sorts of fun stuff, like pxeboot via Wifi.

@johntwillis thoughts?
