WinUsb as a filter Driver

[AlexCS]

Hello,

I'm trying to communicate with a mass storage device via wiunsb. I have succeeded this by installing winusb as a function driver, but I want to know if there is a way to install winusb as a filter driver and preserve my device's features as a mass storage device (preserve USBSTOR.sys).

Is this possible? If so, could anyone help me to install winusb as a filter driver.

Thanks in advanced.
Alexis Cortes.

This is about libusb but the last couple of messages might be useful.

Hi Jan,

Thank you for your answer. Unfortunately I have tried that, I even used an inf to try to install winusb as a filter driver, but I have to say I'm pretty much a begginner with inf's. The driver finishes to install properly, and If I check the 'driver details' on my device's properties on device manager I can see that winusb is installed, however my device gets yellowed banged, and  I'm getting the error that my divice could not start (error code 10)

This is the inf I'm using.

I think in the end it does not work even though the thread says that it works. Further testing shows that WinUSB can not be a generic filter. That test happened to work because libusb0.sys runs as a filter.
