Hi,
I’ve just received two Fio v3’s for an XBee project I’m working on, when I connect them to my Mac they don’t show up as USB devices (in ‘System Information’), nor do I get the ‘keyboard attached’ dialog as suggested by the Sparkfun documentation. When connected both the RX and TX lights are solid, although double-tapping the reset does seem to put them in bootloader mode (slowly blinking CHG light), but they still don’t show up as devices.
