i can't connect to my LinkM on my macbook air running macos 10.7.3.

are other people having similar problems?

when i plug the linkm with attached blinkm into the usb port, i get a blip of power and the leds light up, but then they leds turn off. the green status light on the bottom of the linkm is still on, but i don't see any usb devices load in /dev/cu.*

LinkM does indeed work with Mac OS X Lion (10.7.*) I'm using it right now on my Macbook Pro.

LinkM appears as a USB HID device, not as a USB serial device, so it won't have entries in /dev/cu* or /dev/tty* or need any special drivers. Just the BlinkMSequencer2 app or similar is needed to talk to it.

To probe your USB bus to see if the OS is detecting LinkM, open up "/Applications/Utilities/System Information" (used to be called "System Profiler") and click on the "USB" entry. You will see a list of all the USB devices, one of which should be "LinkM". You can do a similar thing on the command line with "system_profiler SPUSBDataType"

If you don't see a LinkM entry, then the a) USB port may be bad, b) LinkM may be bad, or c) there may be some unknown interaction between LinkM and Macbook Airs. To test for these possibilities, try plugging some other USB device into your Air's USB port. If it works, it's not (a). Find another computer, and plug LinkM into it. If LinkM works there, it's not (b). To test (c) somewhat, try plugging LinkM into a USB hub then the hub into your Air. Because of how USB works, sometimes the interaction of the hub can fix or cause problems.

If that doesn't work, open up the "/Application/Utilities/Console" and plug LinkM in while watching the "All Messages" log. If anything weird pops up, copy it and email it to us at "blinkm @".

If you end up having a LinkM that is bad, contact us and we'll arrange a replacement for you.
