I am trying to set-up an access point (ad-hoc) for my Raspberry Pi. That means I'm trying to "share" the ethernet connection over Wi-Fi. I am doing this using my Ralink Technology, Corp. RT2501/RT2573 Wireless Adapter. When following a tutorial (or actually every tutorial), it immediately goes wrong.

root@pinkypi:/home/pi# iwconfig wlan0 mode ad-hoc
Error for wireless request "Set Mode" (8B06) :
 SET failed on device wlan0 ; Device or resource busy.

I already tried ifdown and not having it in the USB port at the startup.

If it helps, every action with the thing fail (or at least setting the mode). I am using Debian.

I'm sure I'm overseeing something, but I can't find out what. What is wrong?
