The RPi is a toy and a piece of shit. Why anyone would run thousands of dollars worth of equipment off it is beyond me. Toss it and connect your devices to a real PC or laptop.

This. I have 5 of them that I've been using to run my other miners (BFL and BitBurners) and they are notoriously unreliable. Every once in a while the SD cards will die necessitating a rebuild of the whole image. And the USB ports are the worst. Even with a powered hub they aren't able to drive my bitburners anymore and I ended up having to buy a tiny computer and putting Linux on it.
Wow all this hate for the RPi, not sure but they just work for me? I use the MinePeon distro and get months of uptime no problem with my BFL & BitBurner Fury stacks. Maybe I got lucky with good SD cards? Maybe the MinePeon distro is configured to write less data to "disk" and extends the life? I dunno.
But compared to spending $200-500 on a Mac Mini or using an old laptop and having to manage a huge spiderweb of USB hubs off the back and multiple cgminer configs I think I'll stick with my RPi's thank you very much (note I NEVER use usb hubs). One dies? I have a spare. SD card were to die? I have an image I can just reload on a new one and go. And I get to build fun little cases for them out of the old box of legos I have laying around
