Hello, I have a Proxmark3 since 2 years ago, I could use this every day without any problem, but one day, this problem appear in my pc and i can't solve this. If I use my proxmark3 in other pc I can use this perfect, so this is a problem in my pc. I believe that the problem is about drivers, but I search many information and I don't solve this.
If anyone had this problem, please help me, because with other microcontroler (STM32) I have the same problem I believe.
