USB power issue microRusEfi

Post by Kyocmondeo »

I recently got the following message on my laptop after setting up the microRusEfi in my car. On my workbench everything worked fine but when I put it in the car I would get the pop up in the attachment. It basically complained about insufficient usb power.

Turns out MRE does not like extra long usb cables. I was using a 3 meter cable in the car and a 1 meter cable on my workbench. Soon as I shortened the cable in the car all was good.

Looks like it's hit and miss with longer cables. I have two different 10ft/3m cables I am successfully using with microRusEFI, while in yours case your long cable was good for Frankenso data transfer but not good for microRusEFI. So somehow microRusEFI is just a little bit more sensitive to cables.
