Hi,
The following functions should be implemented:
int
libusb20_dev_detach_kernel_driver(struct libusb20_device *pdev,
uint8_t iface_index);
int libusb_detach_kernel_driver(libusb_device_handle *devh, int
interface) or int libusb_detach_kernel_driver_np(libusb_device_handle
*devh, int interface) Detach a kernel driver from an interface. This is
needed to claim an interface required by a kernel driver. Returns 0 on
success, LIBUSB_ERROR_NOT_FOUND if no kernel driver was active,
LIBUSB_ERROR_INVALID_PARAM if the interface does not exist,
LIBUSB_ERROR_NO_DEVICE if the device has been disconnected and a
LIBUSB_ERROR code on failure. This function is non-portable.
man libusb20
man libusb
--HPS
