Windows10 Driver Problem

Post by zjjq »

Hello
When I plug the Adafruit Trinket 3.3 V into my laptop, I could just see the green led turns on and the red led just turning on for a really quick time and turns off. The red led could not be able to pulse. I cannot hear a "Ding" and the device manager could not recognize any device. I followed the instruction online to install the driver. The Adafruit Trinket 3.3 V is new and I just bought it last week. I really hope any engineer could respond to my problem and give me some advice. It is really an important problem for me!
Update: I also tried to connect it to a Mac Pro, but it also cannot be recognized.
Here is the picture of what is showing when I plug in

Secondly, I see that besides the red led is named pin1 , there is another pin1. How could I use that pin 1? If I used digitalwrite(1, HIGH), it will make the led on or make the other pin 1 output 1? Or both
Thank you

The two likely issues are the USB cable and / or the USB port. Make sure the USB cable is not a charge only cable. You may also need to try a different USB port or use a hub:

They are the same pin. Or, to put it another way - the red led is connected to Pin 1. You can see it in the schematics here:

and you would want to take that in to account for your use of the pin. More info here:
