Hello all,

We are looking at ways to detect USB cable connection from a Laptop to our target. Following commands are used to 
startUSB stack and RNDIS drivers on target. Is there an elegant way to detect cable attach and detach?

## Start USB Stack
    io-usb-dcd -dusbrndis-mx6sabrelite-ci ioport=0x02184000,irq=75
    waitfor /dev/io-usb-dcd/io-usb 4
    waitfor /dev/io-usb-dcd/devu-usbrndis-mx6sabrelite-ci.so 4

# echo Start USB RNDIS function driver
    waitfor /dev/socket
    mount -Tio-pkt -o mac=3CD92B010203,usbdnet_mac=3CD92B010204,protocol=rndis devnp-usbdnet.so 
    ulink_ctrl -l1
