HID Komponente : USB_SEND_REQUEST, How-to ?

[waskol]

Ich nicht spache deutch (fransoziche) , Is english OK ? Thank you.

I came on your forum because a lot of people here seem to know well about HID.

- I am using HID Components (from Robert Marquadt)
- I am running under Windows VISTA, Delphi RAD Studio 2007
- My usb device is a Belkin Nostromo speedpad N50 (HID compliant)
- I am trying too lit up the output leds of this device under VISTA (I have succeeded using USBIO driver, wich is not free )
- Under Windows XP, the software provided with the device produces this (this software does not work with VISTA) :

And I am deseperatly trying to write this USB specific request having :
bmRequestType:=$21; (This is a Host-to-device, Class interface request)
bmRequestType:=$09; (Wich corresponds to a SET_REPORT)

In fact, I am trying to reproduce under Windows VISTA, the OUT control message I obtain in Windows XP.

Should I use TJVHIDDevice.DeviceIOControl(), WriteFile(), SetOutPutReport() ?
And How ?

Any help and piece of code will be appreciated. Thank you very much.
