usb snooper

[Gene Heskett <gheskett@shentel.net>]

Greetings all;

I have what I believe to be noise or crosstalk causing interference 
between a wireless keyboard mouse and the machine they are controlling, 
which is an rpi4.  The app itself doesn't expose any usb traffic to the 
user. The effect is as if the finger was lifted from the key for a 
hundred ms or so at random intervals.

So what, on an armhf raspi, do we have for a usbsnoop?

Thanks.

Cheers, Gene Heskett
