How should we write a Multifunction driver ?

Hi all

I need some information about writing a Multifunction driver . We need to
load the Microsoft Audio drivers and HID keyboard drivers for the child
devices in multifunction driver . Since we are planning to use default
system drivers , how would I include those system files along with
multifunction driver INF file ? What I need to do ?

Can anybody focus some light on this ?

thanks in advance

Look into needs and include INF directives. You don’t ship the files
yourself; rather your INF points to the system INFs which will copy over
the necessary files themselves.

Hi Doron

thanks for the reply. I understand what you say . What I could not follow is
, Should I mention Needs and Includes in main INF file itself ( for the
child devices ) ? Or Do I need to write seperate INF Files for each child
device ?
And also if I have to multiple devices of similar type how should I handle ?

We need a driver with multiple audio and HID keyboard devices , but our
device is does not support standard specification that is required by audio
and HID Keyboard spec.
Can you give me some suggestion how to implement this ?

Thanks in advance

You must do the appropriate needs / include from each child INF; ie from
the INF that is actaully installing the device. A further restriction
(which makes sense) is that the device class of each INF must be the
same.

As for suggestions on how to implement this, this is what standards are
for, implement the standard in hardware :).
