Hi everybody!
I deleted everything and started from scratch. The problem still remains, only wlan0 is shown.
But there is one funny thing. I booted the pi without any usb adapters connected. After that I did what
pksato told me and suddenly wlan0 and wlan1 were shown.
If I reboot the pi, only wlan0 is shown again. I have no idea why this is happening.
This is the output of
dmesg after I connected the two wifi usb adapters :

After a reboot only wlan0 is shown again. This is the
dmesg after the reboot. Do be honest, I have no idea what is going on, because my experience about these things is quite limited.

Some other thing I tried, after the reboot.
