Hello, I am using the DSO3254A now.
But, the DSO3254A suddenly does not recognize USB from PC.
Below refer to picture.

The USB recognition failure is displayed every certain time.
The same happens on my PC as well as on other PC.
Please provide a workaround for this issue.
Regards, Lee

I'm not recently install NI software on my computer.
And other PC occurs the same problem.
It seems to be the internal problem of DSO3254A.
Can I reinstall the F/W of DSO3254A?
