I don't know about that low speed "Unlink after no-IRQ" message, but you may be able to fix the other problems by using the "old_scheme_first=y" module parameter for usbcore. Incidentally, if anyone can suggest why some devices like this one fail with the new initialization scheme while (presumably) working correctly with Windows, I would like to here it. The intent of the new scheme was to duplicate exactly the sequence of transfers that Windows uses. The most useful thing of all would be a pair of packet dumps for the same device attached to the same computer, showing how initialization fails under Linux and works under Windows.
