Welp. Got a new cheapo FireLink Opti type card in today (very similar to the Keyspan version I tried previously) AND decided to try all sorts of USB devices. System profiler still barely recognizes the card AKA no Card Model No Card ROM (Yes, the two variants of the Tango 2.0 are pretty different, which is why they need different patches. I assume the first revision (which is a cut down version of one of their other cards) was a stopgap solution of some kind? Dunno.
Yup. But the differences are in the application that installed the patch, not in the actual patch it puts into nvram. The nvram patch is exactly the same in all versions. I think the newer patchers recognise more cards or something, because sonnet's patcher is kinder than mine and will try not to let you shoot yourself in the foot? Don't know.
Oh, and another thing:
Bear in mind that if you install OS 9 without a USB card installed, the USB stack won't get installed at all and installing a USB PCI card won't work. Go back to the OS 9 installer and install the USB support, which I think is in the custom installer (? can't remember, been a while)
I’m eager to still get this Tango card working though. I’ll keep you posted. Now that I have a known good thumb & basic USB drivers it’ll make troubleshoot so much easier!
