E6510 Cabs have R257449 for the ST Microelectronics Accelerometer Sensor driver.
Under the Applications folder there is a Sensor driver and a filter driver folder with corresponding INF and driver files.

There is a newer version available R277312 - I used the /v EXTRACTDRIVERS option on install.exe to extract the newer drivers but there were only Sensor drives extracted (accelern.inf and .sys/.cat)

Can anyone explain if the filter drivers are needed at all?
