Userful MultiSeat is a multiseat Linux desktop virtualization solution that enables a single computer to support up to 11 independent users at the same time, each with their own monitor, keyboard, and mouse by using USB multiseat devices, and virtualizing the X server. This approach offers the features of a full PC including high performance video and significantly reduces hardware costs, support and maintenance costs, electricity consumption, and e-waste as compared to stand alone PCs or thin clients. It installs on popular Linux distributions including Ubuntu and Edubuntu (operating system for schools). It supports 3D graphics, per-seat USB, 2-way audio, and all major USB multiseat devices, including the HP t100, t150 & t200, Acer Zero-Client Docking Station, Viewsonic VMA10, Atrust M200 & M202, GWC DU2600, and Displaylink devices, as well as video cards from Intel, ATI, and NVIDIA. Userful MultiSeat is available as both a standalone package for multi-seat enabling your Linux distribution of choice, and as a bundled install DVD for schools, which Includes Userful MultiSeat, Edubuntu operating system for education, and the ITALC classroom management tool. It was formerly called Userful Multiplier.
GNU usbsync is console-based utility that assists you in keeping files and entire directory trees synchronized between a portable storage volume (such as a USB flash or thumb drive) and arbitrarily many hosts. For this purpose, a special text file, usually named .usbsync, is placed in a storage volume's top-level directory to contain user-written synchronization entries.
Flashrom is a utility for reading, writing, erasing, and verifying flash ROM chips. It's often used to flash BIOS/coreboot/firmware/EFI images. It supports a wide range of DIP32, PLCC32, DIP8, SO8/SOIC8, and TSOP32/40/48 chips, which use various protocols such as LPC, FWH, parallel flash, or SPI. The tool can be used to flash BIOS/firmware images, for example, be it proprietary BIOS images or coreboot (previously known as LinuxBIOS) images. It can also be used to read the current existing BIOS/firmware from a flash chip.
Libpuppy is a library version of the puppy tool, which is used for accessing Topfield DVB tuners (and possibly others) via their USB port. Its main features are listing and retrieving contents of the HD in the device. It allows you to write your own utilities that interface with the device. It comes with two tools, puppy-dir and puppy-get, in addition to the original (mostly unmodified) puppy-tool.
ccid-utils is a USB smartcard driver and development platform. The driver follows a simple synchronous design that supports multiple slots but only one transaction at a time and includes a Python interface. It also includes a command line smartcard shell with a searchable history. The shell, written in Python, offers many useful features for developing with smart-cards and for reverse engineering APDU formats. It includes tools for reading data from GSM SIM cards and EMV credit/debit cards. The SIM tool is very basic, but allows reading SMS messages from the SIM. An example EMV (credit/debit) card tool is included that is boilerplate code for utilizing the EMV C API. There is also a Python interface for the EMV API. A graphical interface for reading EMV cards is provided.
Ejecter is a little tool that makes it possible to unmount external devices and eject CD-ROMs without having to right-click on the device icon (either on the desktop or in Nautilus). It sits in the background and shows an icon in the system tray when one or more peripherals are connected to your PC: once clicked, a window appears with the list of the devices (volume name and device type, and much clearer than the similar thing available on Windows) and the related eject button. Being written in Vala, it is translated into C code and then compiled. This means that it's lightweight and consumes little memory, does not require a full VM like Python, and has no strange requirements to run (just GLib/GTK).
