Usb Driver

NTDEV
1

Hi,

I got this basic doubt when i am trying to install a USB driver. Can we
install a USB driver without having the Device ? ? I was trying to install
the ISOUSB sample. I’ve gone through the “Add Hardware wizard” …i have
tried to install the driver in “Other Devices” category. The error dialog
says that the inf doesn’t contain the hardware information.

Can anybody give me idea on how to install a usb driver… if the device is
not present. any info on this is highly desirable.

Thanks and Regards,
-Naveen

One way is to use a simple and cheap USB device instead of your device to install the driver, an USB mouse for instance. You have to adapt the INF file of the sample to contain the VID and PID of the mouse. Then the sample driver should be loaded if the mouse is plugged in. Of course, you have to modify the sample to work with a mouse (set configuration etc.). Hint: An USB mouse has one interrupt IN endpoint with the address 0x81.

You will have to write a pseudo driver that makes the system think the
device is installed or install the device. Since the PnP manager won’t
enumerate your device, since it isn’t there, then it won’t load your
driver. You can force the driver to be loaded;i.e. the driver entry to
be called, but you won’t ever get an AddDevice call.
