Thank you guys for your hints. Now I found out why it's not working: I have to load uhci.
Reason: I had recompiled the kernel and the new uhci modules was called uhci instead of usb-uhci (because it's the alt one). So, there is a diffence between the compiled version and the kernel source config file at Debian. Debian enters usb-uhci in /etc/modules (which cannot be found) and uhci is not loaded. I have two other usb jacks which needs ohci. I forgot about them and thought the entries I saw (e.g. in /proc/bus/usb/devices) are the ones I plugged my printer to. It would have worked if I have put the usb cable to the other usb jacks. And it works if I load uhci. Thanks for helping me!
