Cannot build Analyzer for luna.gateware.platform.lambdaconcept:USB2SnifferPlatform due to missing power_a_port

[whinis]

Whenever I attempt to build for the USB2Sniffer I get the following error amaranth.build.res.ResourceError: Resource power_a_port#0 does not exist line 102 of the analyzer.py also suggest more issues due to

m.d.comb += [
            platform.request("power_a_port").o      .eq(0),
            platform.request("pass_through_vbus").o .eq(1),
        ]

Those are signals that exist on the LUNA hardware platform, which tell it to let power pass between the target A and C ports and not supply its own power to the A port.

As I understand it, the USB2Sniffer hardware is always in that configuration, so as a quick fix you should be able to just delete that assignment block - though obviously it would be nicer to have a patch that handled this properly for the different platforms.

USB2Sniffer is not always in that configuration but instead uses jumpers to set the configuration. I could add a check for the platform but not sure what the nature of the check should be here.

We've moved the analyzer gateware into the Cynthion repository as per #232. As such I'm going to close this issue, since the code is no longer part of the LUNA repo.

If folks want to port it to other platforms they're welcome to, but our development is going to be focused on Cynthion.
