We have written a Windows 2000/XP device driver allowing these boards to be used with Windows 2000 and Windows XP. The source code is provided for the driver and can also double as good example for Parallel Port drivers taking to ParPort.sys.On-The-Go Supplement - Point-to-Point Connectivity for USB.The On-The-Go Supplement is a new tack on standard for USB allowing for the first time, USB Devices to talk to each other without the need for a "host". While the standard is still in its early days, we look at some of the features of OTG. Philips demonstrated aspects of OTG with their ISP1161 Full-speed Universal Serial Bus single-chip host and device controller. While it doesn’t fully comply to the OTG standard, it does make a wonderful Host Controller for embedded systems such as uClinux.USB with the simplicity of RS-232FTDI has two USB Interface ICs, the FT8U232AM and FT8U245AM which takes the hassle out of USB. One provides a asychronous serial interface, while the other provides a byte wide FIFO with little need to worry about the underlying USB protocols and USB device drivers. Ideal if you are starting out in USB, or you want to quickly add USB to your devices.The Philips PDIUSBD11 USB Peripheral with I2C Serial Interface.Philips has two USB devices which allows any microcontroller the ability to talk USB. However while the silicon has many features which others don't, the data sheets are a little light on content.
