[scope] CW-Husky USB blocked after power-up

[vrozic]

It often happens that CW-Husky USB communication gets block when running the first capture after power-up.
This has already caused CI to break several times.

PR #300 provides a temporary solution.
If the scope is initialised twice, the USB problem doesn't happen. I am not sure why this helps. I will have to look through CW API to root cause this problem and find a more reasonable fix.

Thanks for opening up this issue. Please don't dive any deeper into this. Having a workaround is perfectly sufficient at this point.

In case that we encounter the problem again #245 description contains instructions on how to fix it.
