I have a usb headset (Logitech G35) and I wish to connect it to my n900 via usb so I can use it when I go out. But I need some help. I tried to connect it with HEN but nothing happened. I think I will need some kind of drivers for this. Can some one help me please?

No one can help??

I can not help directly.

In my opinion using a "usb headset" connected only consume the battery quickly. It is preferable to use a "BT Headset".

Yes. I know that if I use a Bluetooth headset or a normal headset is easier. But I wish to use these as they are comfortable and have clear sound. About the battery, that is not a big problem. I have made an external power supply that I can carry with my N900 so I can power external 2.5" HDDs. The problem is the drivers for the headset. I do not know how to add them to the kernel or where they are supposed to be. Keyboards, mice and Ethernet adapters have been successfully connected and recognized by the N900 by installing some drivers into the kernel. I wish that some one would help me.

I think you should connect it to a linux pc, see what name it is recognized with, what modules are used when it is connected, does it require any special software or it just works out of the box ?

with this information you should know what modules need to be compiled into the kernel, but if the headset relies on userspace software, and the sources aren't available, chances to get it working are quite slim.

In windows it is detected automatically as a sound-card. So I think Linux should not be that hard to detect it. I'll try to connect it to Ubuntu and tell you the outcome.

Is this helpful?
snd_usb_audio and snd_usbmidi_lib
I am not an expert on Linux.

well, if the sound works in ubuntu and you just need these modules, that easy enough, they need to be compiled against the kernel you are currently using, if you are using power kernel and don't want to compile them yourself, you can ask pali to compile them as modules into kernel power48.

there is just one more issue, once you get the modules, the device should be in working order, but most probably you will need to go through some configuration to get the audio to route correctly, meaning you will still need to get the software to recognize it and treat it as a headset.

I think it is similar to this right?
can I compile them myself or it is a bit tricky for a novice?
Btw I am using power47.

I tried to do like in the video but with the headset. First I started hen in highspeed and enumerated. Then in xterm I did dmesg | grep usb and it recognised it. Here is the output.
But then the problem is that the sound still plays through the phones speakers. I need to tell it to direct sound to the headset as you told me.
