RE: How to uninstall USB driver from a Pocket PC

When you first insert a USB device which is not known about the function
USBInstallDriver is called when you locate the driver, the driver will then
create the relevant registry keys so that the device can launch.

To uninstall the driver the drivers USBUnInstallDriver entry point would be
called which should (if implemented correctly) remove the registry entries
configured by the USBInstallDriver entry point.

I currently don't know of any application which does this. Alternatively you
could write a program which calls the entry point USBUnInstallDriver within
the drivers Dll to uninstall the device (when the USB device is removed).
Alternatively if you are developing this driver then add a call in your
USBDeviceNotifications function call to call the USBUnInstallDriver function
when the device is removed, but be sure to remove this before testing.

Hello,

I developed USB Host driver for a Pocket PC device. On inserting my device
into the Pocket-PC, it asked for dll. On entering the dll name, it
successfully installed on the Pocket PC.

I can able to see the USB Class name and Dll name on the Windows CE Remote
Registry Editor.

Now, the issue is how to uninstall the installed USB driver from the Pocket
PC?
How to set GUID information in my Registry?
My platform builder does not conatin setupapi.dll, where can I find it?

Thanks in advance.
