Hi Felipe and David, I got 2 USB WLAN dangles which unable to enumerate on MUSB of Blackfin. https://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_id=141&tracker_item_id=4669 It looks like related to VBUS_ERROR retry logic. After one retry in the VBUS_ERROR handler, we got a connected USB device. But MUSB host tried to send out enumeration SETUP packet, it's timeout. I also use USB bus analyzer to capture the bus data, but there is no any data transmitted only some chirps. We googled the discussion between you guys here: http://thread.gmane.org/gmane.linux.ports.arm.omap/10469/focus=10559 Is there any updates about this issue? Thanks a lot -Bryan -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
