Claiming interface: Access denied (insufficient permissions) #19

Closed xeniagda closed 6 years ago

xeniagda commented 6 years ago

I was trying out the read_device.rs example but ran into a problem: when running the configure_endpoint function, claim_interface gave an Error::Access when ran. I suspect this might be a problem of OS X, but I am currently stuck. Any help would be greatly appreciated!

Did you try running it with elevated permissions? On linux I needed to run it with sudo, otherwise it's not able to detach the kernel driver from the device. Otherwise, could you please provide a backtrace of where the access error happened?

It seems like it was me just being stupid, the USB device was already used by another process.
