USB problem with DM8148

Hi

We are using USB0 USB port in our custom board with DM8148. Whenever we inserted USB-B cable we found below error.

musb_g_ep0_irq 707: SetupEnd came in a wrong ep0stage setup
musb_g_ep0_irq 707: SetupEnd came in a wrong ep0stage setup
musb_g_ep0_irq 707: SetupEnd came in a wrong ep0stage out/status
musb_g_ep0_irq 707: SetupEnd came in a wrong ep0stage setup
musb_g_ep0_irq 707: SetupEnd came in a wrong ep0stage out/status

When the same cable disconnected we got message "musb g_hid gadget disconnected."

Can u please let me know even though Processor is able to detect USB , why the above error is encountered. I checked for all hardware connectivity , power and everything looks just fine. 

Thanks In Advance

    Hi Madhura,

    Are you using EZSDK/PSP? If yes, which version?

    Can you try to reproduce this issue on the DM814x TI EVM, is it applicable there also, or only valid for custom board?
