Hello, I would like to create my own slot machine from my PC. For that I am looking for some slot buttons that can connect to USB, or for some separate keyboard letters to connect through USB ( EG : I would need a hardware with USB plug , that will be just 1 keyboard button and have size of a keyboard button ). If I can buy 1 KEYBOARD BUTTON that connects via USB, I can easily customise it's design. Does anybody know if that kind of hardware exists ? Or any ideas on how to solve this ? …

So, I've been having a rather hard time configuring this because the flash drives totally screw up when you try to safely power off the system, so I figured I'd tell you how to do a persistent usb install without this... trouble. You'll need to have an 8gb or bigger flash drive for this to work properly. First, Download the BackTrack 5 R2 iso image to your computer (assuming that you are on backtrack linux) into your root home directory. Second, Download the "unetbootin-linux-568" executable from the unetboot website. Third, Stick in your flash drive and edit the partition tables …

None of the other "can't find mouse" descriptions apply to my problem. After using SnowLeopard on a Mac Mini for 1.5 years, twice now I've found my computer turned off after leaving it on overnight. Ok, that could be a power glitch. No one else touches this computer, so that isn't something to investigate either. The problem occurred - on two occasions now - when I turned the computer back on -"No mouse connected -.Looking for a wireless mouse or trackpad" Wha? I'm using an Apple mouse connected to my keyboard, just the combination I bought at the Apple Store. …

Before going into the problem, here is some hardware/software information: Device accessed: Ohaus Scout Pro Digital Weight Machine ([url="http://www.northshorecare.com/ohaus-scout-pro.html"]product link[/url]) Interface used: USB ([url="http://www.carolina.com/product/702448.do?s_cid=ppc_gl_products"]product link[/url]) Serial Port: COM3 OS: WinXP Python Version: Activestate Python 2.7 pyserial version: 2.5 Python recognized this serial port and had no problems opening it. I am new to python as well as pyserial. I couldn't figure out how exactly can I read data from the serial port. I used the following code: [code]import serial ser=serial.Serial(port='COM3',timeout=3) s=ser.read(100) #reading up to 100 bytes print s[/code] This prints nothing. During those 3 seconds timeout, I placed an object …

Hi i own the logitech Nano Vx laser mouse, which worked fine for nearly a year. But recently, the cursor stopped moving, and the whole mouse wouldn't work. I tried changing batteries, restarting the computer, installed the Set point Software, and tried it out on other computers and usb ports, but none worked. The light on the switch of the mouse was on, but the battery light on the top was off, and i noticed that every time i put the laser in contact with a surface, the mouse switched itself off completely. When i hold the laser in the …

My computer crashed and my Syntek (Crescentec? ) USB2 video capture adapter is useless now since I can't remember where the Ulead CD with the driver is. It worked great for years - I hate to throw it away ! The STK1100 and STK1600 drivers don't work with the 1120 chip. All the DC-112x download links dead end. Anyone ?

Afternoon, I'm running a xp system w/ USB keyboard and mouse. Mouse has decided to have a mind of its own. Essentially when i want to click on something it does not respond. It is almost like, when I try and click on a window, it immediately goes to the background. Scrolling has also become an issue. I've tried several mice (all usb) same issue. I can move my mouse around and use my keyboard w/ no problems. Eventually if I wait long enough the mouse will enable for a bit (all while in XP). I can use my mouse …

Hi, this is the case, I have a Win 2003 server with scsi RAID controller; this server has a usefull special, not frecuently used application but the installer for this application are no longer available. Now the server (as a machine) is a waste, because it is only turned on only when the application is requiered (about 4 times a year and by 5 to 8 hours each time). Years before, this server was the core of a company organization, now it has no reason to exist, except for getting historical information. The idea is to: 1) use the server …

Hi, I am trying to create a service for my windows application. The service would just call an application if it detects a USB device inserted on the computer. I want to register for device change notification to receive all the usb device event messages.

But using the Windows Service project in Visual Studio 2008, I cannot find anyway to get …

Hi, I spent a lot of time searching for a solution to a problem I was having getting into CMOS with my USB keyboard, which is connected to a KVM switch. All of the USB options were enabled in Integrated Perpherals, but the keyboard wasn't functional until after the boot sequence and DOS started up. The solution was to make sure the USB cable was plugged into USB port #1. I found this suggestion in a paper in the MS Knowledge Base regarding USB/Motherboard HID compliance. Regardless of whether your keyboard is connected to a KVM or directly to your …
