Well, so far, no luck on the Pegasus. I'm using a D-Link DSB-650 (translucent i.e. rebranded) I'm still plugging away. I have been trying to run the drivers manually as well, but to no avail. (Said that it couldn't load the ppp dll or the qnet. I tried loading without those too and it CLAIMS to load, but I don't even see a light on my USB adapter.
Thoughts?
And CallerID isn't working for me in the USB image. At least not from shelf.
(FYI, in case you hadn't noticed, I'm new to QNX/Audrey hacking. But I love it!) 
***** I also want to make an IMPORTANT CORRECTION to my earlier statement... Apparently I got lucky the first time writing the wrong size of image using Gem. I used Gem to save the contents of the CF card to a file and then used that file size with ntrw.exe. That also appears to work. For some reason, even Linux has misrepresented the size. 
For those keeping score at home.. (from Windows)
1) Download gem (link above).
2) Run it w/ your CF card in a USB adapter.
3) Select the SCSI device for your adapter. (mine is a "(USBAT Compact Flash )")
4) File|Create Image from Physical Disk and give it a name
5) Use this filesize of the created file as the size parameter for mkcf (mkcf jukebox.usb1 audrey.flash <size>)
6) ntrw write audrey.flash f: (change f: do your drive letter)
7) Power-up Audrey with the card in place and the datebook button depressed. (not suicidal, just depressed)
8) If it doesn't bitch about invalid images or checksums and finally boots to a new image, repeat 7 but press both datebook and power buttons.
And to the developer of NTRW, I'm sorry I ever doubted you.
