Trinket Pro Trellis Soundboard not working

Post by gewi »

Hello!

I bought the portable trellis soundboard. built it and installed it completely. Arduino IDE with libraries and windows drivers. On win 7 and 10 with two usb cables no port was shown, so i cannot upload the sketch...

What can i do now???

Thank you for your help!
