Actually (RM20.11 V1.6.0) only USB to Network LAN-Adapter with the chip set Realtek 8153 or Realtek 8152 are supported.
In next releases it is planned to integrate an USB to CAN and to Wifi dongle. Further information will follow.
If there is a special need for a specific USB device please get in touch with us directly.
I used the recommended "CSL – 300 Mbit/s WiFi USB Stick Adapter Stick/Wireless LAN/WiFi Dongle for PC/Mac/Linux/2T2R MIMO" with "Realtek RTL8192CU" and it worked out of the box.
Not sure if it is okay to post shop links here, but I ordered it here: https://www.amazon.de/dp/B06Y43BKQ1/ref=cm_sw_em_r_mt_dp_ATPSTVES1EDEKVS5D1CB?_encoding=UTF8&psc=1 but might be also available elsewhere.
I have ordered exactly that. I have ordered another one specified as RTL8192CU, sadly i have received two RTL8192EU. Anyway bot chipset relies on the same driver. As specified DevWiki . Ubuntu has such driver already present in kernelspace by default, is running as befaulti inside the PI4 with standard ubuntu core installed. I do not have the "netplan-wpa..." entry to be filtered in the logbook.
Is there something i can do?
Really thanks for the help.
EDIT: after 4 wrong dongles i got a RTL8192CU from Aliexpress and it is working correctly 😎. I still don't understand why the CE version is working and the UE is not.
