I received today the dongle, and I ask to BrosTrend for the ticket for rpi drivers, but today is friday and probably to monday I dont receive any reply. Do you remember how to install and where I can download the drivers for my RPI4?
It took quite a while (the driver had to be compiled, but all was automated), but after it finished, I restarted the Pi and the Wifi stick worked perfectly. Then you have two Wifi devices in your Pi, wlan0 = builtin Wifi and wlan1 = BrosTrend stick.
