Got hex2bin scan error with 3.8.3 on a Jalapeno, pretty sure I compiled everything correctly.
If you're getting hex2bin scan errors there is some kind of data corruption since it's only meant to have text characters and finding something else. One possibility is you're on a usb1 slot - are you using an ancient PC?
Nah, using a raspi. 3.5.x and 3.6.x find the Jala, it's just 3.8 that won't. I think it might be because I have a shitty USB hub. But then it wouldn't work with 3.5 and 3.6...
Got the Fury working with 3.8.3 and now getting nearly 2 gh/s more per device.
That's nice.

Which fury did you use?
Bitburner Fury, getting roughly 52~54 gh/s.
