As I said earlier, the delay was put *before* most of the data gets written. More specifically, I inserted a delay of one second between transmission of magic1 and magic2, one between magic2 and magic3, and one between magic3 and the first firmware file. If I additionally insert a one-second delay before the fd is closed, I get this usbmon log: http://stuff.onse.fi/gobi2000/gobi-regression5.mon.log The firmware upload is still unsuccessful. -- Anssi Hannula -- 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
