I have an OpenCR 1.0 Board. We followed your instructions on the website (http://emanual.robotis.com/docs/en/parts/controller/opencr10/) but I cannot find a USB port on the board.
How to fix this?
My normal caveat... Robotis will hopefully give you additional suggestions.
But looking at your jpg, I am pretty sure you are not Windows version 10? Did you install the Serial driver as shown in the manual?
Like the photo, the Arduino IDE software still cannot find USB port. I think the OpenCR 1.0 board have a problem.
Sorry I can not really see anything in that photo... Again hopefully @willson will help you figure out if it is hardware issue and needing a repair....
But if it were me, some of steps I would try first, is things like:
a) Again make sure the appropriate Serial driver as no driver is installed by default for this Serial adapter by Windows7... If in doubt maybe uninstall and reinstall...
b) If you have some form of Linux installed on something (PC, RPI, ....) I would try connecting the OpenCR board to it and see if anything shows up in the system messaging.... Example I would plug it into an RPI, then in command terminal window, I would type something like: dmesg | tail -30
And see if anything shows up...
I would also look at output of the command: lsusb
c) I would try to use the recovery mode to see if that helps. http://emanual.robotis.com/docs/en/parts/controller/opencr10/#references
I would look at c1) below as well to see if when you enter DFU mode if anything shows up in device manager...
c1) On my Windows machine I would try to update the firmware on the OpenCR board... That is if you follow the instructions for updating bootloader: http://emanual.robotis.com/docs/en/parts/controller/opencr10/#update-bootloader
If you try to force board into DFU mode does it show up in device manager, like they show? If so follow the instructions to burn bootloader.
d) I would try other simple things like try a different USB cable. There are some charge only USB cables which don't have data pins connected, so they won't work.
Unlike Windows 10, Windows 7 requires to install the driver if it is not automatically installed.
Please make sure that the proper ST driver has been installed on your system.
If the board is not properly recognized, try manual driver update by right click on the device and locate the driver file folder.
If driver installation keeps failing, like Kurt mentioned in the above reply, try bootloader update.
Please note that you'll need to install the DFU driver if OpenCR1.0 is not recognized during DFU Mode(something like "STM32 Bootloader" under Universal Serial Bus Devices in your device manager.
