perfstr Posted November 15, 2022 Posted November 15, 2022 Hello, just discovered ability to support legacy USB gadgets. There is UDC called max3420_udc and also gadgetfs module. By using startup script mkdir /dev/gadget modprobe max3420_udc modprobe gadgetfs mount -t gadgetfs none /dev/gadget it appears to be possible to use old gadget developed for kernel 3.4. It was descibed once in the link https://forum.armbian.com/index.php/topic/1759-usb-gadget-built-for-h3-processor-on-top-of-gadgetfs/ just line else if (stat(DEVNAME = "sunxi_usb_udc", &statb) == 0) { should be replaced by line else if (stat(DEVNAME = "musb-hdrc", &statb) == 0) { Hope this helps. Just curious, where would it be possible to find any information (in Armbian documentation) about that? 0 Quote
