[sudheendra]

Hi all,

I am using kubuntu 7.10.

I have connected the USB DSL router (Dataone). the device is detecting, but there is no driver. in device list, it shows "unwown device". How to install and configure the usb router in my desktop?

Secondly, after installing desitorrents extension for firefox, firefox quits at the begining itself. i am not able to see its window also. How to remove  the extension in this case. where is the mozila firefox extension folder?

Please help me in this regard.

Thanking you,
