Free usb hub software for linux

pvrusb is a Linux driver for the WinTV PVR USB (not the plain WinTV USB), a USB MPEG2 encoder with a TV tuner. The WinTV PVR USB is a video capture device attached to the USB bus. The purpose is similar to the PCI version (WinTV PVR), but this driver is for the USB version only. Follow this link for a Linux driver for the PCI version.

This device has also not much to do with the plain WinTV USB, because the WinTV PVR USB contains a MPEG2 encoder, which the simple WinTV USB does not contain. The higher compression ratio of the WinTV PVR USB gives much better video quality at higher resolutions than the WinTV USB. Support for the Pinnacle Bungee is still incomplete.

Some notes about the program:

You need the WinTV PVR firmware ROM from Hauppauge ("HCWUSB.UPD.ROM" or "USB_MPEG2_POPNOISEFIX.ROM"). I obtained the files by installing the WinTV software on a Windows machine. The files do not contain any copyright notice, but for now I just assume Hauppauge would not want me to distribute them and so I wont.
You can upload the firmware into the driver after inserting the module using:
dd if=USB_MPEG2_POPNOISEFIX.ROM of=/proc/pvrusb/firmware bs=256k
To display information about the currently loaded firmware:
cat /proc/pvrusb/firmware
The driver attaches itself to /dev/usb/lp0 (yes, the USB printer special file). YES, this is stupid. I will change it soon.
To save the MPEG2 stream try:
cat /dev/usb/lp0 > data.mpg
To watch TV attach a signal to the composite input and use MPlayer:
mplayer /dev/usb/lp0
The tuner is not programmed yet. I will probably add tuner support soon.
I have a WinTV with NTSC tuner. I cannot add PAL tuner support until I get access to a PAL WinTV.

USB Launcher project is a couple of basic programs to drive the M&S USB Missile Launcher.
ctlmissile does all the actual work. Youll need libusb installed to compile it, but assuming you have that typing "make" should do the trick. You can then
do:
ctlmissile up
ctlmissile down
ctlmissile left
ctlmissile right
ctlmissile fire
ctlmissile stop
to do all the things youd expect. Note youll need to be root to use it. I
havent figured out a nice way to use libusb yet as a user. Anyone got some pointers?
Oh, and youll need to not have usbhid installed or itll claim the device itself (I think I can add support so that it gets automatically disconnected from the device, so Ill have a look at that).
usblauncher is a Perl program that uses GTK2 to provide a basic interface for controlling the launcher. It uses ctlmissile. Currently Ive made ctlmissile suid root so I can run usblauncher as my normal user id, but Im not sure about this long term.
Enhancements:
- Added support for Dream Cheeky USB missile launcher from James Puderer.

libusb is a library to provide userspace access to USB devices. libusb project supports Linux 2.6/2.4/2.2, FreeBSD/OpenBSD/NetBSD, and Darwin/MacOS X.
Operating System support
- Linux
- FreeBSD
- NetBSD
- OpenBSD
- Darwin
- MacOS X
Building:
It should be as simple as running these two commands:
./configure
make

USB Headset Buttonss purpose is to enable the Volume up and Down Buttons on my Logitech USB 30 Headset.

USB Headsets are very useful for VoIP applications like SIP Networks or Skype. On my headset I have volume buttons which need extra care to be taken of. This Application does it.

vp-usb-lock is a Linux kernel driver and PAM module that utilizes the PC wireless USB lock and makes it possible to use it as authentication method for your Linux box.
It is easy to install, but needs access to the sources of the kernel and PAM to build correctly. It has been tested under Fedora Core 2 with a custom made 2.6.7-1.494.2.2 kernel, but it should also work with other kernel versions and distributions.
Enhancements:
- A lock daemon was added.
- A compilation error that was introduced lately by some changes to the Linux kernel was fixed.
- Support for kernel 2.4.x versions was added.

PIC USB Framework is a USB application framework dedicated to Linux (on the host side) and to the PIC 18F4550 family of microcontrollers (on the device side).
PUF includes: a bootloader that can flash the PIC application through the USB, a PIC demo and its corresponding application on the host side, and docker, the host-side flash programming utility.
The PUF also contains gputils and sdcc as cross-building tools, and odyssey 0.4vasco as a parallel port PIC programmer.
Enhancements:
- sdcc optimization flags are now switched on by default.
- A component library (including a console mechanism and a small real time scheduler) has been added to help building user applications.
- Tools have been upgraded to automake 1.9.6, autoconf 2.59d, sdcc snapshot 4482, odyssey 0.5, and gputils 0.13.4.
- The applications size has been optimized.
