USB HID and Interrupt OUT transfers RRS feed

  • Question

  • Hi

    Am I correct in thinking that Windows CE 6.0 does not support USB Interrupt Out transfers through the USBHID driver?

    I see from the documentation that there is a LPGET_INTERRUPT_REPORT function but there does not seem to be a LPSET_INTERRUPT_REPORT function.

    I don't have much idea on this but see if the following URL will help you

  • Hi GSR

    Thanks for that.

    It seems (from the HID specification) that supporting interrupt out transfers is optional and Microsoft have chosen not to implement a way to use them from the USBHID driver, presumably because that driver has been designed specifically to support raising events in GWES for keyboards and pointing devices and only needs to do LPSET_REPORTs to control things like the Ctrl and Num Lock LED's in keyboards.

    I just wanted to make sure that there really was no viable way to use USBHID to do what I need to do.  It seems that I'll have to re-think my approach to my problem;-)

    Best Regards
