I do have serial port and regular USB connected to the Rocket board, but I don't think that's the issue. The Quartus tools see the jtag just fine. It's eclipse that is being retarded.
And I don't think it's a matter of drivers, etc. Eclipse appear to require some type of database to know what types of debug targets are available. The "Debug Configurations" is supposed to have an "Altera" entry with a bunch of sub entries below it. I suspect if my only issue were the jtag not being seen, this Altera tree would still show, but the error would be farther down the tree somehow. Instead, I see absolutely no hint that Eclipse even knows WTF Altera is, much less anything about Jtag.
