I am pleased to report that after uninstalling and re-installing from the Software and Reference CD-ROM R.29
all of the PicoTech software for the PS2202 and running through the exact
installation steps outlined in the PicoScope PC Oscilloscope Installation Guide
I was able to get the PS2202 to work in the following configurations:
Apple Mac Pro w/ Windows XP SP2 on Boot Camp 1.1.2
Apple MacBook Pro w/ Windows XP SP2 on Boot Camp 1.1.2
Then, upgrading to R5.15.6 also yielded successfully working configurations.
Under no circumstances have I been able to get either machine to work with the PS2202 running Parallels Desktop Build 3520 (or otherwise).
So, the long and short of this is that the scope absolutely, positively works with Intel-based Apple hardware. However, it appears to only do so, when Windows XP SP2 is directly in control of that hardware, as opposed to being proxied through a virtualizer like Parallels Desktop.
Now, considering my iPod and other USB devices work in Parallels, I suspect there's some small software issue in either one or both of Parallels and the PicoTech drivers/software.[/i]
