Compatible USB isolators for JS220

The Intona 7055-D works, but with the following caveats:

  • provide external power (aux input), as joulescope draws more than the intona can provide without external power.
  • for the link of the computer to the intona, I found that USB 2 cables seem more stable. I have had a number of computer/hub ports unstable when using a seemingly good quality USB 3 cable. When failing, console says kernel AppleUSBXHCIRequest: AppleUSBXHCIRequest::finish: transfer completed with status 0xe00002ed

The latter might be interesting to look into. How can I debug that from joulescope?

Also, in Running Joulescope on high voltage I have seen that I’d need to bridge both sides of the joulescope to prevent more than 48V over it. The recommendations that were given for the JS110 also apply to the JS220?
