Re: how to read data fom vendor class devices or composite device

First piece of information, don’t use Numega (Compuware). Driver Studio
sucks hard. It’s extremely buggy. Also, like you, when
I started playing around in the kernel enviro, I also thought Driver
Studio would give me a head start, instead it only helped me waste
several months - all it did was give me a distorted view of the kernel
environment and introduce bugs that surprisingly were not my fault.

Spare yourself the time and trouble, and download KMDF. That will give
you a better driver and in less time. Not too mention, I’m
sure these Microsoft guys would help you with it - they seem to love
talking about KMDF. You can tell their very proud of their work
and have every right to be…

Dear All,

How to Read the Data from Philips LFH 5272/00 Composite device ,it is vendor class device , please give me your suggestions and solutions .

The Philips LFH5272 already has a driver. Have you tried downloading
one from Philips? I would wager that the buttons are on a HID-class
interface, which means that you should be able to read the HID reports
from a user-mode application.
