You may find this log a bit more useful than the dmesg > log linked to in my previous email.

It can be bad usb connection, noise or not enough power. -- Regards, Oleksij -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
