Hi,
You should look at the things that change when you install the cab file. As
I told before, most CAB installs do 2 things:
1. Copy the dll driver file(s) to the platform windows map. Some might copy
control panel applet's to that destination as well. (If so, you will have
additional icon's in your control panel)
2. Add some registry keys so that the USB host knows which driver it should
install when the device is connected.
So, if you wan't the device to be recognised by the OS, you will have to
include those step's yourself.
If you connect your platform to a PC (I like active sync to do this) you can
use the remote registry editor to check your device registry. You can copy
the keys you need and insert them in the platform.reg of your platform.
check the HKLM\USB\LoadClients\xxx
There you should find under \default\default\xxxx the " DLL REG_SZ
xxxx.dll" registry key. This is the name of the driver. The first xxx after
the loadclients refer to the VID and PID of the device. This should be the
unique numbers each USB device uses to identify itself to the host.
You can copy the dll back to your development pc. You can include it in your
OS by adding it to the platform.bib file section.
Your new created image (with the registry setting and the driver dll
included) should recognise the device without user intervention or driver
installation.
Hope this helps.
regards,
Luc

Yes. You are absolutely right. I followed the sequence:module
1) Download the image.
2) Copy the CAB file using Activesync.
3) Insert the USB cable into the HUB
4) Double tap it.
If I insert the device after installing the cab file, it identifies
the device.
But in real time scenario, I'll connect the gsm module inbuilt. So
while downloading image I want the device to be identified.
How can I do that?
Give me some apt solution. I have done so many work arounds, all but
in vain.
Thanks in advance...

Hi,
Did you install the driver on your platform?
What do you mean with "The device isnotdetectedif it is inserted while
booting?"
How do you know that it isnotdetected?
Is your problem that you can only use the device if you plug it in after
powerup, or can't you use it at all?
You say you will install the driver once the device is identified. You
should do things the other way around. You have to install the driver so
that the OS can identify theUSBdevice. Without driver, it will show you
the unidentifiedUSBdevice and allow you to manually tell it which driver
to use. If the driver is ok for theUSBdevice, the OS will create the
necessary registry keys, so that theusbdevice driver will load
automatically, the next time the device isdetected.

Thanks forthe reply.
If I insertUSBcable from GSM module after bootup, it gives the pop-upfrom
that I understand that it identifies the device. The driver for GSM
installis
available in the form of .CAB file and once if it identifies, I'll
identifyit.
What I want is on power-up, if my module is inserted, it should
6.0the
device.
How can I do for that?
Could you clarify do I include any uhci/ehci from catalogue items?
Already I included OHCI in my image.
Thanks very much in advance.
