Hello, I am starting tracing the source code of hci_usb, and want to test the Alternative Setting patches from Alok. But I have some questions: (1) In hci_usb_isoc_rx_submit, I saw the usb_rcvisocpipe are initializing settings for Host-side. But why is it necessary to call usb_submit_urb() to send the urb, and then repeat infinitely in hci_usb_rx_complete when the returned count is 0? Is that mandatory to do this to permit the usb device to send data up to Host? (2) Why the isoc is set to 2 in the beginning? What will happen when we set it to something like "5" in the beginning? (Alok's patches seems to dynamically adjust it depending on hdev->conn_hash.sco_num) Thanks, Jui-Hao ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
