[Pyusb-users] usb.USBError: could not claim interface 0: Operation not permitted

[Nguyễn H. Q. <ng....@gm...>]

Hello.
I'm trying to use PyUSB to write a program communicating PC - PIC
microcontroller. First, I tried with my USB Flashdisk and Bluetooth
dongle. But when I used the function handle.claimInterface(0), I
received an error: "could not claim interface 0: Operation not
permitted"
Please explain me this error and instruct me the way to be able to
communicate with my device.

You probably need root access.  Use sudo or su.
