[libusb] Open device on Android

[Antão A. <ant...@gm...>]

Hi all,

I've been researching for a while but I'm misssing some essential parts.

I already know that I need to request the user permission to access the
device and then pass the respective file descriptor to libusb.

I successfuly built the latest libusb source but then how do I pass in the
file descriptor?

I also tried to use some of the many forks that add an fd parameter to
libusb_open() but then what do I pass in for the first parameter? Do I have
to get it from libusb_get_device_list()? If so, how do I map the Android
UsbDevice or UsbAccessory to a libusb_device?

Thanks in advance,
Antao
