You can try to search by LIBUSB_ERROR_BUSY in internet. Probably some driver or other application already open this device

[chrontax]

The issue is probably that a driver cdc_acm has opened the device, but I have no idea how I could solve this.

Nevermind, seems I wasn't looking for a usb library, but a serial library
