Since doing a clean install of Windows 7 on the W520; there have been a few curious issues with the Lenovo drivers.
Firstly, the FireWire controller quite simply doesn't show up. Doing a tweak to Device Manager shows that the computer knows that the device is there, that it has seen it at some point, but that the device "isn't connected" (a code 45).
There don't seem to be any drivers for the device itself in the driver matrix.
Is there really a problem, or is this just by design? Does the controller not show up unless you have a device connected (I don't have one to test with) like the SD reader does?
EDIT: The device just seems to show up by itself. Don't know if that's going to be persistent across reboots, though.
Secondly, there seems to be a conflict between the Intel and Lenovo (Broadcom) drivers for control of the Bluetooth software.
Installing the Lenovo drivers first yields working Bluetooth (it has in the past). But, after installing the Intel drivers (for the wireless card, an Ultimate-N 6300), it no longer works.
If I try to install the Bluetooth drivers after I've installed the wireless card, the machine claims that there is no Bluetooth device present.
It seems that (in the Intel installation) I can't deselect a certain option that seems to over-ride what the Lenovo drivers are supposed to accomplish, and that quashes all attempts to start the BT radio (the tray application won't start).
Solved! Go to Solution.
