DeviceIoControl发送IOCTL_SCSI_PASS_THROUGH出现121错误

我使用DeviceIoControl先USB 设备发送IOCTL_SCSI_PASS_THROUGH指令，结果出现121错误，121错误在说明是信号灯超时，问问大家如何解决？ BOOL status = DeviceIoControl(hMassDevice,
IOCTL_SCSI_PASS_THROUGH,
(LPVOID)&m_sptwb,
(DWORD)inbuffersize,
(LPVOID)&m_sptwb,
(DWORD)length,
(LPDWORD)&returned,
NULL);
