i have 2 camera. It worked just before, but now it doesn't work.
The error is as follows.
I don't understand why it doesn't work.
it work in opencv code(no sync),
it work in each standalone camera with sdk code.

usbcommand.c (904): usb_cmd_write(). Write command(80000001) ended in failure, Command status 0x00000001

color_mcu.c (284): usb_cmd_write( colormcu->usb_cmd, DEV_CMD_SET_SYS_CFG, (uint8_t *)&sync_config, sizeof(sync_config), NULL, 0) returned failure in colormcu_set_multi_device_mode()

k4a.c (883): colormcu_set_multi_device_mode(device->colormcu, config) returned failure in k4a_device_start_cameras()

    Hello @yh c Please have a look at this Github issue, which may help.

    Unable to connect to Kinect Sensor Camera

    So there is something wrong with your device or there is something wrong with how its connected to the PC and we are not able to reliably read it. Do you have a 2nd device you could try out ?.
    I am going to assume this is the version reported after factory resetting the device (which can only be performed once - until a new image is successfully installed).

    Make sure you are using the factory cables and factory power supply to power the device while confirming the device works as expected.

    What USB Host controller are you connected to (#1088 (comment))? Try different USB ports on your PC.

    If you think the firmware version reported is accurate, then I would recommend exchanging the device for a new one.

    Please comment in the below section for more help in this regard.
