Hello,
I know that there are a lot of problems with with wifi-sticks which don't support monitor mode, but I am able to put the same adapter into monitor mode on my laptop with kali-linux 1.1.0a and 2.0. My problem now is that on my raspberry pi 2 with kali-linux 2.0 installed I can't get the adapter into monitor mode.

Here are some of the command outputs on my laptop:

dmesg

Now the output on my pi:

As you can see airmon-ng can't find the phy interface for the adapter. The driver seams to be the same but for some reason the the chipset text is slightly different, but i guess thats not a problem. The lsusb output is the same. The dmesg output of my laptop mentions, that a special firmware is loaded etc. All this stuff is missing in the dmesg output of my pi. It seams, that my laptop referes to the adapter as the rtl8192cu adapter that it is, but my pi refers to it just as a general usb device.


I think there is a problem with the drivers (it's every time a driver problem -_-). Of course I searched the internet for this "rtlwifi/rtl8192cufw_TMSC.bin" and drivers that would help me but I couldn't find anything..
