In some hardware path , USB Device was not found

[陳柏儒]

hello,

 

My image is (Armbian BookwormXFCE desktop 20230831) and download to cm4 moudule.

 

When I using the Bananapi CM4 base board ( https://wiki.banana-pi.org/File:BananaPi_BPI-CM4_base_board_1.jpg) the USB function is working.

But I using the common RPI CM4 base board, such as waveshare's cm4 nano-b (https://www.waveshare.net/wiki/CM4-NANO-B) the USB function is not working.

 

I compare the difference of two board's schematics. Bananapi's base board is connecting the fs1.1 usb hub ic. but waveshare's base board was connecting USB D+/D- to USB host directly . 

I also tried bananapi official image (both Debian and Ubuntu mate) and the wareshare's base board USB function is working.This is a bit confusing to me. Why can’t USB be found when connected USB D+ / D- directly in Armbian image?

How can i solve this problem? 

 

Thanks

If that doesn't work, you are more than welcome to donate to Armbian so the baseboard can be purchased and a proper OVERLAY or DTS can be created for it. As I will not be buying another baseboard out of pocket to do so.
