Really curious. One hour ago, I went to my computer store of confidence. The first cable we tried, that seemed really "modern" worked well, so I could flashes my device, setting the hour and now I'm reading about the configuration options for prepairing it. In the next days, probably I'll ask more questions, but really thanks for your time, Alex. Hoping you have a great week!

Windows 10 Home. I put the "Mode: Custom", then connect with batteries and MicroSD Card. Two lights start to blink (red and green). Then, I switch to USB/Off, and only the green light continue (with another cable, both turn off). Whatever, the message is: "No Audiomoth found. Make sure the USB Cable is connected and switch in in USB/Off)". I use really "ancient" cables because I only have cables with micro USB 3.0 that are a little bigger than the micro-USB port from AudioMoth, so I think that, if all the stuff go well, probably it's the cable. But all opiniones are welcome, because I'm really interested in starting to work with AutioMoth.
