edimax ac600 wlan stick on rp1b+ not working

Hello supportteam,

i need help getting my edimax ac600 wlan stick to work on a raspberry pi B+.
After activating the Load WiFi Interface in the WiFi & Network configuration tab i get the folowing message

Debug: Saving WPA-Supplicant (Successfully initialized wpa_supplicant Could not read interface wlan0 flags: No such device WEXT: Could not set interface ‚wlan0‘ UP wlan0: Failed to initialize driver interface )
Data saved
Status: WiFi USB adapter status is not active. WiFi connection status is not active
(Only WPA/WPA2-Encryption possible)

I assumed WLAN is a premium feature so i bought the 5-years-licence and activated it.
But after rebooting i get the same error message. There is no wlan0 device, which is surprising as max2play sells a edimax wlan dongle in the shop and guaranties it to work. I understand it is not the same device but the wlan chip ist commonly used with the rasppberry pi and should be supported.
Here are some infos from my setup
