I was working with my Wixel pair this morning and performed a "write to wixel" using wixelconfig. A permission denied error was issued in the console and that particular device no longer illuminates any leds nor shows up in lsusb when plugged in. The other wixel seems to work fine as normal when plugged in to the same port, cable, etc.. That is, it shows up in lsusb and the leds illuminate. When I plug the "dead" wixel into my antique Windows XP computer, I see the same behavior. It remains dark and doesn't show up in the device manager, the good wixel does show up and illuminates its leds.
In my limited experience with these devices, I'd guess that I killed it somehow. Do you think that's true? If so, do you know any technique I might use to restore the device to an operating state?
