MicroSD-usb3 adapter wont boot from internal usb


Until a few months ago I was using a usb microsd adapter with a microusb-emmc connected to the internal usb. After it no longer worked due to a fault, I decided to change the model. I’ve tried several but even the latest lexar doesn’t seem to work with Eon. I tested it with pc and it works fine, it allows me to boot from usb using my emmc-microsd. I set the rpi to boot from usb first but i can’t fix.
