Are you using a pc running Windows 8. That was my problem. Worked fine on an old laptop running Windows 7

same happened with me. It turned out there was a prompt on my M8's screen asking for permission for my computer to use USB debugging. I gave it access and adb was working fine.

I had the same problem on windows 8. I installed HTC sync and everything worked fine.

Make sure USB debugging is enabled.

When you connect your phone and use the 'adb devices' command for the 1st time your phone will give an USB debugging RSA prompt. Click ok and you will be good to go in windows 7. Just run the 'adb devices' command again (or click on the UP arrow on the KB, this will replicate the last typed command) to check it sees it.

Windows 8 - No idea

I must have missed that prompt, is there a way for me to do anything that will have that prompt show up one more time? I am running windows 7.

Turn off usb debugging. Give the phone a reboot.

Turn USB debugging on again and connect it to your PC again

Look at the phone

It should come up again. Make sure it is set to 'always authorise'

Type adb devices = profit

I had the same issue on my Windows 8 pc.. I was able to rectify the adv device not found issue by going into device manager , clicking on the HTC one icon and manually installing the drivers by browsing through my computer and using my Nexus adb drivers and everything worked fine after that

Download htc sync, you'll need those drivers. Then follow grentuu's instructions.

Thanks a ton. I had just plugged my m8 in after a fresh win8.1 install and couldn't figure out why I could copy files but not see it under ADB after the adb google driver install.

Glad I could help!

I had the same problem using Windows 8.1. adb and fastboot were definitely installed correctly as I already used them for flashing other ROMs on my Nexus 7. The solution in my case was to download and install the HTC Sync Manager. After installing the hsm the adb and fastboot commands worked perfectly.

Best regards,
B.
