In my case some of the descriptors coming back from the device are bogus when the device is first seen. The device then disconnects, and when it is seen again by the kernel, nearly one second later, the descriptors are fine and there are no errors. vid/pid change from hardware ODM to OEM, suggesting that my device simply isn't ready when Linux first talks with it. //Peter -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
