My Arduino bit was working fine. I went to load a new bit of code, it hung for several minutes, and now none of my computers will recognize it. I’ve tried it on a 32-bit XP laptop and a 64-bit Win7 desktop. I’ve tried two sets of USB cables. I’ve tried replugging it. Depowering it a couple of times in rapid succession. Switching the analog switches to PWN. Unhooking the other bits. Rebooting the computers.
When I plug it in the “Arduino Leonardo bootloader” will show up as COM5 for a few seconds. Then it vanishes and I get a new “Unknown device” in my device manager.
Has anyone had this trouble? I’m worried I’ll need to reflash the bootloader. Any suggestions would be welcome. Thanks.
