To verify this open DevTools or review a Har file and if they say the below and your Vendor ID is 0000 then the Generic device can not be added.
"text": "{\"message\":\"line 0: vendor_id must be greater than 0\",\"error_code\":\"BAD_REQUEST\"}\n"
See if USB device has an actual VendorID, try in a different system and see if it is reported.
If it is reported see if there is a driver problems for onboard USB controllers for the one that reports all zeros.
