Hello, I use the usb_bulk_msg() kernel function to write and read to and from a USB device respectively. Sometimes the usb_bulk_msg() is missing to deliver an incoming packet. This packet is seen however by an USB analyser (Beagle USB 480). A fragment of the Beagle log is located in the attachment beagle.csv. The packets in concern have the index number 1132287 and 1132325, where the first is a device request and the latter is the missing corresponding response. A measurement with usbmon shows that this very response is not delivered by the host controller driver. The packet with index d3196a40 in the attachments usbmon.txt (complete traffic) and usbmon_filtered.txt (only the traffic with the device in concern) show that the request is sent to device but the corresponding response is never delivered. -- Guenter Gebhardt
