HID help

[doomass]

Hi all -

I'm having a heck of a time getting any of the HID attack stuff working. After having no success from the GUI, I went to the shell. When I enter this command:

echo 1 | /usr/bin/hid-keyboard /dev/hidg0 keyboard

I get the error:

/dev/hidg0: Invalid argument

This happens regardless of whether I have MTP enabled or disabled. I also get the same error over and over if I go into Kali Menu mode and pick any of the brute force attacks from the USB attacks menu, which leads me to believe that something is gooned up with /dev/hidg0.

Do any of you have a clue for the clueless? I searched every single Internet and couldn't find anyone else who posted about this problem.

I'm running NetHunter v1.1.0 on a Nexus 7 2013 WiFi.

Any help would be greatly appreciated.

Thanks,
doomass
