U-Boot not booting USB as of release-2024-03-11?

I am not sure if this is happening only for me since I didn't see any other reports yet of the same problem.
After a fresh DFU macos 14.4 install on a mac mini m2, I followed the asahi installer and selected UEFI, rebooted and saw asahi logo and uboot text, but it was not able to boot from the usb that was created with nixos image.

Maybe I did something wrong in the process of dd-ing the image to the usb?
dd if=nixos-24.05.20240309.3030f18-apple-silicon-release-2024-03-11.iso of=/dev/sda conv=sync

The problem is that at the moment, the keyboard is not recognized either in uboot to press any key to stop the boot process. I did try multiple keyboards, multiple usb sticks and all ports, yet no success.

It seems that the problem originates from the usb A ports not being recognized by u-boot. Using a type C usb made it work.
It would be good if this piece of information was added in the installation documentation until the problem is fixed.
