Here are thee steps I take with tricky device:
*) Identify the device by VID, search web.
https://wiki.debian.org/HowToIdentifyADevice/USB
*) Install firmware, confirm loading (dmesg) and device has IFACE(ip a).
https://wiki.debian.org/WiFi
*) use ifupdown
https://wiki.debian.org/WiFi/HowToUse#Command_Line
*) increase verbosity with ifup and/or wpa_suplicant
Good Luck,
