Hi Chris - I'm currently going down this road myself. It depends on the USB device. If it is an HID device then just use the Jedi libraries (they come with demos with source code). If it is not an HID device then you need to either write a device driver for it, or the device may support basic read and write through ReadFile, WriteFile, and DeviceIOControl but it should come with documentation on how to do that.
The Jedi libraries you may need are the HID, DBT, and SetupAPI. They also have demos that show you how to discover any devices that are attached to the computer (and on) and get notified when they are removed or attached. Hope that helps, cheers, Phil. ----- Original Message ----- From: "Chris Veale" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, July 13, 2004 9:32 AM Subject: [DUG]: Data capture from USB? > > Hi all. > > Has anyone had any experience capturing data from a USB port? > > I have a component here that I use for collecting and communicating > with a serial port, but I have a possibility of needing to collect and > communicate with a USB port (and also mabye a parallel port) > > Are there specialist components to do that, along with thoughts about > usefulness of these? > > Just so you dont invest large amounts of time trying to help me out, I > havent started looking yet ;) Just thought I'c come to the experst > first... > > Cheers > > Chris > > ______________________________________________________ > > The contents of this e-mail are privileged and/or confidential to the > named recipient and are not to be used by any other person and/or > organisation.
