After a few days of my car being off but still connected to its main power, when I turned it on, I noticed that none of the USB ports were working.
I don't understand what your car has to do with it.
Even the 'lsusb' command returns no output. I updated the EEPROM but the ports still didn't work. In the bootloader section, the system detects the connection of USB devices. The image during bootloader is transparent and indicates the current conditions. The main power source is 5 volts at 27 watts, and there are no other consumers like fans or other outputs connected to the device, yet there was no change in the conditions. I checked the voltage of the DI+- and Ground hardware-wise and found about 1.5 volts for DI+- and 5 volts for USB. Is there a solution to this?
