Using WinUSB with USB Device Simulator
Hi Everybody,
I am working on USB client app and would like to use WinUSB functions to read and write to USB channel. I also would like to use provided with WinDDK usbsamp driver and SoftUSBLoopback.dll to implement the simulated end of the USB device.
I have followed instructions (WinUSB (Winusb.sys) Installation) to update usbsamp “Intel 82930 USB Test Board” driver (usbsamp.sys) to WinUSB (winusb.sys) driver so I could use it in my client app. I have modified my inf file (provided below), and update completes successfully but then when I call WinUsb_Initialize – it always returns 0.
Regards,
Janusz
