Woo-hoo. Finally.. I have a working APRS setup. Originally I was fooling around with gpsd and dumping the contents to a USB Serial adapter to my OpenTracker, but fought with the serial drivers for a while, then found the APRS patches to Mapper and fooled around getting Scratchbox installed so I could compile and so on.. Ultimately, I drug my feet long enough that now it all works. MicroUSB to MiniUSB adapter MiniUSB OTG to USB.
