FT245RL IC testing software. You can set the output and get input status from your PC’s screen. It is thus possible to enable or disable the 8 channels, for a 8-channel input.

This is just a friendly FYI to all hackers. Once you get a little more adventurous you can get real confused about what usb devices are plugged in etc (which com ports,…)
my best new friend is usbdeview from nirsoft http://www.nirsoft.net/utils/usb_devices_view.html
It shows you everything about the plugged in usb devices, updates on the fly, v good

The AVR Stick is a simple data logging device that instantiates itself as an HID keyboard and reports the voltages, along with a ‘timestamp,’ from two pins on an ATtiny85. The device uses open source firmware availabe from Objective Development (http://www.obdev.at/vusb/) called V-USB to implement the USB 1.1 standard. The code that runs the application was based on the EasyLogger example application from Objective development.

A DCF77 time signal receiver with USB connection. Emulates a serial interface (COMx) using CDC and works with Windows 2000 to 7, 32 or 64 bit, and with Linux. Should also work with Windows 98, Me, and MacOS.

I like the handy DCF77 signal. In this project no clock should use it, instead the computers in my home network should be served by a precise time reference. Due to the fact most other interfaces are no longer available on modern computers, it uses the USB to forward the prepared DCF77 signal to the host.

USBTemp provides a thermometer. It is based on the DS18S20 digital thermometers. In addition, the thermometer connects to an USB port – you can read the temperature using a commandline tool. In combination with RRDTool you can easily create temperature graphs

What i am making here is a USB lock with smartcard key. The idea is that a phonecard reader made with a PIC micro will be able to store a number of different phonecards into memory. Whenever one of these cards is inserted into the slot, it will activate a 4-ports USB On/Off switch. If the card is removed, the USB ports will be de-activated.

Ettus, manufacturers of the USRP line of SDRs, has announced the availability of a customized bootable USB drive for USRP/GnuRadio development. The LiveUSB SDR Environment is a 16 GB USB 3.0 drive with Ubuntu 11.10 (64-bit), USRP Hardware Driver (UHD), GNU Radio, OpenBTS and associated documentation preinstalled.
Ettus notes that this drive is compatible with USB 2.0 ports, but the system will take longer to boot, load programs, and respond to user interaction.
The US list price is $79.00. Good news: Ettus is making a .tar.gz file with the file system available for free download here. If your hardware is 64-bit/USB 3.0, give it a try!
