Logitech keyboard on linux, could not set config as device or resource is busy - linux-device-driver

Question

I have a Logitech G613 keyboard for linux. It works fine except that the G(1-6) keys are mapped to F(1-6) by default and there is no way to remap them without remapping the F keys.
So, I went through a lot of resources on the internet and found g15daemon and libg15. Unfortunately, libg15 does not support G613 but I found a way for the library to detect my keyboard by adding the following line
DEVICE("Logitech G613",0x46d,0xc53d,G15_KEYS),
The only issue now is, libg15 detaches the kernerl driver from the device with usb_detach_kernel_driver_np(), which is successful. But after that, the call to usb_set_configuration() fails with
USB error: could not set config 1: Device or resource busy
Output of hwinfo before detaching kernel driver

Also, once the driver is detached, the keyboard stops functioning. It has to be reconnected again to be functional.
Can anyone please help me understand why usb_set_configuration() is failing?
