I'm trying to get my CM4 up and working but I've some trouble with USB
I've build an image for the Raspberry Pi 4 family (seems to be the same firmware for all the versions)
It works well on a Raspberry Pi 4, at least USB2 and PCIe, my modem doesn't start when plugged in a USB3 port
Enable of device-initiated U1 failed
Enable of device-initiated U2 failed
Not a big deal for now as I'd like to use it with USB2 and PCIe.
After these tests I decided to move on the CM4, with CM4IO carrier and nothing is detected on the USB ports, even a keyboard or a mouse are not detected.
The command lsusb doesn't report any device.
From the CM4 datasheet, the USB is disabled by default, to enable it you need to add a line in /boot/config.txt
After applying this and several reboot, power cycles, nothing new with the USB.
I'd like to make the CM4IO work before debugging my custom carrier.
Anyone has a clue to solve this issue?
