Suman, I had no problem using Ralink usb-ethernet adapter. I used it on Ubuntu 7.1 with a rebuilt kernel, Backtract 3&4, and even windows. As a matter of fact I left the card running over two nights to obtain enough IVs on wifi network, it had no problem what-so-ever, although it was relatively hot to the touch. I haven't been using the card since, but if you want; I can retry using in on Ubuntu 10.10 (kenel 2.6.35-22-generic, i think). I agree with Alan and Greg that overcurrent is a HW issue. Upgrading kernel is probably not going to help. You should try to use Y-split usb-cable and/or powered usb hub. -toan -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
