last update synopsis: i’m able to see/program the boards again, but i don’t know why. long version: after unsuccessfully trying to get the IDE to see the board under windows via the bootloader mode reset x 2 sequence, i rebooted the mac into OS X and noticed that the serial port (/dev/tty.usbmodem1411) has reappeared. i was able to download the blinky test sketch into the board, switch to the second board and perform the same thing. i rebooted the linux and it was able to see the board again. my w-a-g is that there’s an issue with the USB dialect that the board uses.
Update: Using windows 7 and arduino IDE 1.0.5 + the above addon files, I tried the recommended remedy for getting into bootloader mode and loading a sketch; i’ve not been able to get into bootloader mode (50+ tries).
after my initial prototyping with Pro Mini’s, I bought a couple of Pro Micro units because it would eliminate the external power supply. following the instructions for the Addon files, i was able to program both units (one via a Mac, the other via Linux both with Arduino IDE 1.0.5) using an example from RF24 library to verify my wiring. the functioning setup was disconnected overnight and now neither board is recognized (i.e. the Mac and the Linux setup exhibit the same behavior). i’m stuck. this seems to be a known issue (e.g. http://mrgazz.com/blog/computers/computers-mainmenu-138/hardware-mainmenu-140/sparkfun-arduino-pro-micro-and-linux and https://forums.freebsd.org/viewtopic.php?&t=37505 and https://forum.sparkfun.com/viewtopic.php?f=32&t=37466). is there a documented solution to this?
