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.

Sir, did you install a software with NI recently on your computer?
Please replace a computer to test.
Author: hjlee@leolsi.com Time: 2018-3-2 07:41
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?

Hello,
I had the same problem with a 3254A: the windows detected the oscilloscope in the Device Manager, but it couldn't communicate with it.
This happened all of a sudden after using it ~6 month.
Tried the solution above, now the oscilloscope is not detected at all by windows.
When powering up the oscilloscope, all the 4 external led flash at high intensity then stay at mid intensity. The 2 leds on the board stay on.
Any other solution?
Thank you.
