from the vendor database:

idVendor 0x081f idProduct 0xe401 Generic Controllers / SNES USB Controller MaxPower 500mA

from the init:

cfg.bMaxPower = 250

could it mean the ESP cannot provide 500mA and the snes gamepad negociates a lower voltage it can't sustain?

I'll try another power source. If I understood you correctly, of course. When powered by usb 3.0, it was the same
