USB Custom Mouse Device with 2 Interface

NTDEV
1

I’m facing the following question in customizing the AchorChip’s device
driver to work for my custom USB device which expose 2 interface.

a.) Mouse
b.) A Reader Device

I am thinking of the follwing possible solutions :

Method1:
1.) How to call the vmouse.vxd from WDM USB device driver

  • I’ve the sample source code to talk to the USB chip from AnchorChip:
    ezusb.sys
  • If I receive the mouse position information from the firmware, how do
    I talk
    to the vmouse.vxd (should I?) to control the mouse pointer?

OR

Method2:
2.) How to layer the WDM USB device driver(ezusb.sys) properly to let
the mouse
work as
HID while we can still CreateFile into our device driver to do
DeviceIO…

-I’ve tried to place the ezusb.sys as a filter driver or mini driver,
but if it
is in the middle layer, I cannot do a CreateFile and sending IRP to it.
If I
put it as the Upper Filter driver. The mouse stop talking to the HID.

OR
Method3:
3.) How to interface a USB device which has 2 interface :

  • mouse
  • custom device
    -Maybe my understanding on the driver is not right as the above. Could
    u
    recommend the right way to do the job?

I’ve posted my message to a few newsgroups but nobody reply to me, please
anybody help me, I am desparate to seek for the solution.
Thanks.

sincere,

Hi :
If both interface are HID class, you can use the Microsoft’s driver . Then
talk to your device through HIDClient.

Hope that help

The other device is custom reader device, we have been using the ezusb.sys
(WDM device driver for their AnchorChip) to do the IOCTL before this.

Can I use 2 inf files :
1.) Inf files for HID mouse
2.) Inf files for the USB Reader (Class = USB)

With the same Vendor ID and Product ID?

OR

Is it possible for me to put the ezusb.sys as a lower filter driver and
send IOCTL to it? (Upper filter is not possible so far as it block my
mouse from being recognized as the HID to control the mouse pointer, or I
am not correct in my test? )

OR

Whether it’s possible for me to use the same ezusb.sys , but how can I call
the vmouse.vxd?

Thanks for ur reply.

Hi:
It should be composite device right? then hook up each interface with the
driver which you like . you would need only one INF file. Take a look of
Keyboard.inf

Good Luck

But in single Inf file I can only have only one class type right? Either
Class= USB or Class= Mouse.

Can two line with the same VID and PID exist in the Inf?
%USB\VID_0566&PID_2800.DeviceDesc%=USBMouse, USB\VID_0566&PID_2800
%USB\VID_0566&PID_2800.DeviceDesc%=USBReader, USB\VID_0566&PID_2800

Yet the user still need to setup the device twice, right?

***********

By the way, I have a sample on Philips’s PUSHKNOB mouse, the put a lower
filter driver which provide a powerful functionality. Can I put the
ezusb.sys as a filter driver as well? But do u know whether I can send
IOCTL direct to the filter driver in Win98 SE? (I saw a article provided
by Eliyas Yakub saying that it’s possible in Win
2000)

Thanks.

Hi :
Look more carefully of Keyboard.inf. Beside VID, PID , composite device
also include interface for its Hardware ID.

Good Luck

You mean the MI_00 at the back?

[PHILIPS_KBD]
%USB\VID_0471&PID_0401.DeviceDesc%=USBKBD, USB\VID_0471&PID_0401
%USB\VID_0471&PID_0402&MI_00.DeviceDesc%=USBKBD,
USB\VID_0471&PID_0402&MI_00
%USB\VID_0471&PID_0601&MI_00.DeviceDesc%=USBKBD,
USB\VID_0471&PID_0601&MI_00

Mmm… I don’t have any information in hand on that yet. But I will try to
find out.

Thank you Michael!

Hi:
This is what I mean. May be you would like look KEYTRONIC_KBD as a example
, it specify the keyboard interface hardware ID as
USB\VID_03F9&PID_0102&MI_00. and Mouse interface hardware ID ( in
MsMouse.inf) as USB\VID_03F9&PID_0102&MI_01

Hope that make more clear
