Pseye with Processing

Hello, I'm trying to use a pseye with Processing. Processing have the library but there is a permission bug to access the camera.
Here's the errors messages > libUsbException: USB error 6: error LibUsb.claimInterface: Ressources busy

libusb: error [_get_usbfs_fd] libusb couldn't open USB device /dev/bus/usb/001/004: Permission denied
libusb: error [_get_usbfs_fd] libusb requires write access to USB device nodes.
org.usb4java.LibUsbException: USB error 3: Unable to open USB device: Access denied (insufficient permissions)

You should probably file an issue on their github:

I just looked, there is nothing.
Thanks for help
