- 5V Supply Derives Power From 3-Wire RS-232 Port - The circuit of Figure 1 produces a semi-regulated 5V output from an RS-232 port. Unlike a PC-mouse supply or comparable circuits that rely on the modem-control signals DTR and RTS, this one operates with a 3-wire port (GND, Rx, and Tx), and obtains power only from the Tx line. The output current-about 8mA-is sufficient for CMOS microcontrollers and other low-power circuits. Rate this link

- Buttons for USB HID Devices - USB Human Interface Device Class design information Rate this link
- Hints and kinks for USB decoding - At PC-accessible USB receptacle and at the peripheral receptacle, the USB signal has the format of differential-NRZI (nonreturn-to-zero-inverted) code. After conversion (with a simple circuit or test probes) of this differential to single-ended signal, the signal becomes a waveform that assumes the voltage levels used to recognize ones and zeros in computer code.

USB port interfacing project information
The USB is a serial data-transmission system that uses cables to connect peripheral equipment to PCs. All new computers have two or more USB receptacles, and the predictions are that they will replace most of the legacy receptacles on older PCs. USB system is master-slave tybe bus. The PC is the master that supplied power to the bus and controls the bus operation. The peripheral equipment connected to USB bus just follow the PC controlling. USB system is quite complicated, and if you plan to interface something to USB, you need practically always use special ICs designed for USB interfacing. Those ICs typically include USB controllers and general purpose microcontrollers with built-in USB controllers.
