            Bug ID: 242131
           Summary: libusb_set_auto_detach_kernel_driver(3) causes
                    libusb_claim_interface(3) to fail
           Product: Base System
           Version: 12.0-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---

usb.cpp

The attached usb.cpp fails (when the supported device is present) at
libusb_claim_interface when libusb_set_auto_detach_kernel_driver is called
before it.

Removing libusb_set_auto_detach_kernel_driver makes libusb_claim_interface to
succeed.

I had to patch the port misc/openhantek with the workaround for this issue in
order to make it to work.
