Pixy connecting to roborio via usb

[sabercatrobotic]

Our team has purchased a Pixy camera this year. We decided to try to use USB to communicate with the roborio. This has been the primary source we have been using.

After getting through a wide range of problems, we are stuck so close to the end.

We have tried to make a swapfile, but whenever we try to enable we get this

admin@roboRIO-4146-FRC:~# swapon /swapfile1
swapon: /swapfile1: Invalid argument

We're kinda at our wits end. Does anybody have any ideas? If this doesnt end up working, we will probably switch to IC2 or SPI, but USB would be preferable.

Thanks!
