vocab = Vocab(counter, min_freq = 1, specials=('\', '\', '\', '\'))

I am struggling to get Windows to load the default WinUSB driver for my device. Please note that I am looking for a solution that is using BOS descriptor (and not the old 0xEE string index).
The device enumerates and Windows tells me that it is installing the device, but the WinUSB driver is not loaded. I have tried everything that I can think of, but still I can't get Windows to load the driver. I even uninstall the device and delete the USB flags in the registry whenever I re-try, but to no avail. Is there anyone who can help me to get this to work?
I don't want WebUSB capabilities or anything additional. This is a non-composite device.
This is my BOS descriptor (as sent over USB):

This is my attempt to transfer from a row of data from one object to another. I am wondering if there is a more efficient way to do it.
Elements within the list selected_city_codes

original data and attempt
...ANSWER
Answered 2022-Jan-20 at 13:25I'd suggest using spread syntax along with Array.filter() and Array.includes() to get the required arrays.
The first array will include all elements in airport_data_1, along with the matching elements in airport_data_2.
The second array will include only the filtered elements from airport_data_2.
The arrays will be modified in place.
