I am have similar problem with USB Isochronous transfers. My problem is that when I changed bInterval value fram 2 to 1. audio frames drop happend. Do you have solved the problem? could you give me some suggestions, thank you very much.

Code: Select all

static struct usb_endpoint_descriptor hs_epout_desc = {
	.bLength = USB_DT_ENDPOINT_SIZE,
	.bDescriptorType = USB_DT_ENDPOINT,

	.bmAttributes = 0x05,//USB_ENDPOINT_XFER_ISOC ,//| USB_ENDPOINT_SYNC_ADAPTIVE,
	.wMaxPacketSize = cpu_to_le16(1024),
----.bInterval = 2,
+++.bInterval = 1,
};
