    Question

    Dear Sir/Madam,

    I am writing a VB program to access a USB device (HID class) using API. However, I must need to poll it at a fixed time to check if there any data from the device. Is there any Event that I can receive the USB device data like a COM port interrupt event?

    Thanks for your help!

    That's my prob as well. Since this post is kinda old, maybe meanwhile someone has got a clou?

    I need to attach a very simple kind of remote control to a PC (4 to 6 Buttons and kind of speed control, either analog (Pot) or incremental encoder. For a quick-and-dirty solution the game port is just fine, only what new PC still has one? So I'm looking into USB, but it sure would be nice not to have to poll. Ideally there would be an OCX that fires an event like MSCOMM. Anything for not having to poll...
