USB device not recognized

I bought three AudioMoth 1.2.0 on the last GroupGet. When they are plugged into the computer I get a message that reads USB device not recognized. Under device manager it shows "Unknown USB Device (Device Descriptor Request Failed)". I get a steady green light when the switch is on USB/OFF and plugged into USB. It is not recognized by the Flash or Configuration app. It is the same with all three audiomoths. I have tried the paperclip FLASH method with no change. Any ideas?

Yes, I am using configuring app to connect AudioMoth. I am using windows 10 pro.

Exactly i am connecting AudioMoth to configure but in the configuring app but device is not recognised by the configuring app. So please help to solve this.

Double check the USB cable first. Ninety percent of connection problems turn out to be the USB cable. Then check in Device Manager to see if you can see the AudioMoth listed in USB devices.

Just tried a cable that came with my Beats headphones and that seems to have worked. Onwards - and hopefully upwards! Thanks again!

Any USB cable with a micro-B connector should work. However, there are now lots of cables available now that are really 'phone charging cables' which don't have the data wires inside them. These are often not marked and look identical. Just make sure that what you get is sold as a USB cable.

I use the Apple USB-C to USB dongle, and then a regular male USB A to male USB Micro B cable.

Thanks, Alex I really appreciate this! I already have the dongle so it's just a question of acquiring the other part of the cable. I'm not technically minded so setting up my Audio Moth is a steep learning curve for me - as will be the next steps, I suspect. so good to know help is out there!

Regarding the required cable, I was surprised that no information was given about the requirements on the otherwise excellent set-up information - other than it was not included. The information about the micro SD card and batteries was most helpful. Looking at the forum, it seems I am not alone in having cable problems.

I'm also having connecting my audiomoth to my computer. Can either of you help with obtaining the correct cable? I'm using a Macbook Pro V11.4. What kind of USB connector attaches to the Audiomoth?

Thank you both for the help. It was in fact a problem with the cable. Even though it was purchased specifically because it was suppose to be capable of data transfer, that apparently was not the case. What an frustrating standard USB is.

Great. I'm glad this got resolved. It's nearly always the cable!

Did you use the same USB cord ? Maybe this could be an issue too, some USB-Cords are made to be an Powersupply and have no "Data pupose"

Thank for the top Martin.

I have tried connecting to now three different Window machines and one Mac, still with no luck.

@Alex Rogers I have tried a couple different cables, including one that I bought specifically because it said that it was capable of data transfer. I suppose it is possible that the cable is still the problem, but the device is noticed by Windows (with an error message) but not "recognized". The charge only cable I was using before showed up no where in Windows.

What drivers are needed? I was under the understanding, after reading some comments in the forum, that there were no drivers required in Windows.

Much Thanks

@Gideon Ney You only need to install drivers on older Windows machines. Windows 10 and Mac should normally work fine straight away. The "Unknown USB Device (Device Descriptor Request Failed)" is very unusual and I haven’t seen report or experienced that before. This sounds like a hardware issue which is strange if it is affecting all three devices in the same way.

When you say ‘I’ve tried the paper FLASH method’ what did you manage to do? Did they connect to the Flash App when you did this? Did you manage to update the firmware this way?

Also can you confirm if you’ve tried this with and without batteries.

Hy Gideon, in my case, i "fixed" this Problem in switching to an other computer. I think it has tu do something with an incompatibility with the USB-Controller on the Motherboard - just guessing.... .

I hope itis some kind of usefull for you, knowing that its not an fixing the Problem regards
