Hi There,

I have an Openscope that I've used a few times, but today when I went to use it there appears to be no connection to my Windows 10 PC?  I re-installed the agent software, rebooted the laptop tried again but I get the message "No devices found"

Openscope is not appearing under Device manager, i checked the USB port and cable by connecting another board which does appear.  I tried this on a 2nd WIN10 laptop, same result.  Also tried 2 USB cables, no change.

On plugging in the LED's LD5 & LD6 blink for a fraction of a second, then after a few seconds the blue LED LD4 blinks.  I can put the board into bootloader mode so there is some functionality in the board, just no connection to either WIN10 laptop?

Rev F board, DA4C288.

Thanks ~DaveS

So I found another micro USB cable and figured I might as well try it out with the Openscope, it worked fine?!?  So I have 3 cables that work with other devices, but only one of them works with the Openscope.  So if you have issues, try as many different cables as possible as not all USB cables are made the same :)

Hi @DaveS,

I'm glad a different cable worked, though as to why this is the case (or why different boards work with different cables) I do not know. I believe (I haven't gotten confirmation) that Digilent changed out the micro B USB cable that we sell to one that was tested to work consistently, though I have personally been using the same cable that was found to problematic for the last 5 years without any issues. So I'm glad you were able to find an easy solution.

Thanks,
JColvin

Hi! I came across this post while trying to find a solution to a similar problem. I have tried all the USB cables I have and none of them have worked. When i try and trigger, LD1 doesn't stop glowing, and LD5 and LD6 flash occasionally, and the signal never shows up, but it continues to try and sample. LD4 doesn't flash. I used to also get an error message that said that there was a data transfer issue and data chunks were lost. I have the latest firmware update. I have tried resetting the device but when I go into the configure panel, it tells me  that it could not connect to the device. I have also tried multiple ports, and my laptop recognises that it is plugged in so I really have no idea what's going on now. It was working the night before and all of a sudden in the morning I came across this issue. It would be great if this could be sorted out as quickly as possible, thanks.
