I gather from the instructions that I should be able to connect using the mini usb cable on the microRusEFI after powering on the device with the key (without starting the car). Has anyone else had issues with this? Is it a power supply issue? If it is relevant, I am using the same cable when connected to the car and when disconnected from the car, so that should not be the issue.
Below I have included the relevant lines from linux's dmesg to show that the device is recognized, but the computer can't connect to it successfully. I have had this type of issue before when a microcontroller has a power issue.

Where can I find a pin mapping from the pins that show for analog sensors in TunerStudio (eg AN volt 9) and the pins on microRusEFI (eg AV9) I assume this is the correct mapping, but I would like to know for sure.
Finally where can I find the mapping from the 48 pin connector harness to the microRusEFI. I am trying to use the stock MAF for the time being since I don't have a vacuum hose routed at the moment. If I understand correctly I should just have to change it out of Speed Density into MAF mode, and set up the MAF sensor to the correct pin. I believe it might be
