how to install the drivers for usb adapter in raspberry pi (i am using raspbian wheezy) i am using usb wireless 802.II n wifi adapter. i tried the lsusb command but i am not able to get the device id of wifi adapter.when i tried using iwlist scan command ,wlan is not displayed instead only lo and eth 0 is displayed please help ? thank you in advance
I see three reasons for this to happen:
You have another device connected to the second USB port which needs a lot of power and the WLAN adapter doesn't get enough power any more. Try to connect the WLAN adapter or second USB device or both via an active USB hub to your pi
Your WLAN adapter is broken. Try to connect it on your desktop or labtop and check whether lsusb returns some details.
You have a very exotic WLAN adapter. Please post more details about your WLAN adapter. Maybe your seller has a webpage describing the WLAN adapter ?
