AM335X- how to enable the USB1 on SDK8.0

Hi Joe,

I've run mu beaglebone black with a custom built kernel & my usb port detects the devices connected to it:

 root@am335x-evm:~# [   60.861946] usb 2-1: new high-speed USB device number 2 using musb-hdrc

[   61.047066] usb-storage 2-1:1.0: USB Mass Storage device detected                                                      

Can you please share:

 1. the output of lsmod on your board

 2. boot log of your board

Best Regards,

Yordan

Also, I noticed that you haven't set the MUSB_DSPS driver in the config fiel you attached. Try setting CONFIG_USB_MUSB_DSPS=y in your config file.

Best Regards,
Yordan

Hi Yordan,

Thank your help. My board information as below,
