Winusb APIs - How to use

Shalaka_Gujar · October 11, 2008, 9:06am

Hi All,
I am writing a usb driver. My host side driver is not winusb driver. Still
to develop host side application, can i use winusb APIs?
Or i will need host side device specific APIs /IOCTL /PDK?

Please guide me.

Thanks & Regards,
Shalaka

You cannot use winusb.dll if you are using your own driver. Why can’t you use winusb.sys?

I already have a host side device with driver. I am not writing a driver for
host side device.
Can i suppress my original driver of host device and use winusb as host
driver for my host device?

Please guide me.

If you want to do that, sure. This will not be transparent to your app though. The app will have to change to use the winusb DLL APIs

Yes, WinUSB API can be used from the application only if WinUSB driver
is loaded for the device.
I used WinUSB api for bulk and interrupt transfers successfully. If
you are not dealing with Isochronous transfers, then you can load
WinUSB driver and use the client routines from the application.

Hi,

Thanks . I am able to load winusb driver on my host side device. I took the
help of “WinUsb_HowTo.doc”. As per instructions given in the document, i
write my “.inf” file for my host side device and it works…

can i use winusb in wireless usb application? I am writing wireless usb
driver and application for the same. At host side, i have planned to use
winusb APIs for data transfer. Am i on right track?

Please guide me.

I am glad that winusb is working for you?BUT, if your eventual goal is to have these wireless usb devices be controlled by KM drivers (let?s say a wireless usb keyboard so it will be controlled by hidusb), you will need to integrate into usbhub or create your own bus driver which supports the URB interface. Either option will require a KM driver, winusb just doesn?t work in that scenario.

Hi,

I am a bit confused. From below mail thread, i have concluded that for wusb
driver, we should have host side device driver.
However, we can use winusb but then we need to integrate winusb driver(host
side) into usbhub.
Will it be right way to integrate into usbhub ? or it will be better to have
original driver.

Please guide me.
