Thank you for your help.
I'm trying to run the SHARC Audio Module on a USB device with the Audio Project Fin attached.
The SHARC Audio Module P10 and PC are connected via USB.
In the first GET_DESCRIPTOR request sent from the Host (PC),
the RXPKTRDY bit of USB_EP0_CSR0_P is true and the Host can be answered.
The request from this Host is sent with Address = 0, Endpoint = 0.
Then, when the SET_ADDRESS request is delayed from Host,
the RXPKTRDY bit of USB_EP0_CSR0_P becomes true,
and the received Address is set in the USB_FADDR register.
The request from this Host is also sent with Address = 0, Endpoint = 0.
Next, a GET_DESCRIPTOR request comes from Host with Address = received Address, Endpoint = 0,
but the RXPKTRDY bit of USB_EP0_CSR0_P does not become true.
The RXPKTRDY bit of USB_EP0I_CSR0_P, USB_EP0_RXCSR_P, USB_EPI0_RXCSR_P will not be true either.
The USB signal is monitored by LINEEYE's LE-650H2.
Please tell me how to deal with it.
