Answer 1

the poiter for you is look into libusb library.

starting with libusb_get_device_list which Returns a list of USB devices currently attached to the system. http://libusb.sourceforge.net/api-1.0/group__dev.html#gac0fe4b65914c5ed036e6cbec61cb0b97

you can take it from there.

if you want other way reading /sys/bus/usb/devices directory and read valid devices. except root hub or other hubs.
