drivers

I've installed Visual FoxPro driver from this link on my 64 Bit Windows 7 Home Premium OS and tried to register vfpoledb.dll using REGSVR32. I could able to register this dll but when run my application which accesses VFP database is throwing the following error: System.InvalidOperationException: The 'VFPOLEDB.1' provider is not registered on the local machine. The same application is working fine in 32 bit Windows 7 Home Premium OS without any issues. I have googled for 64 bit VFP driver and found out that there are no VFP drivers for 64 bit OS from this link . Kindly help me to resolve this

Upon considering the driver side implementation for DirectX API on windows systems for modern video cards I was wondering why this implementation is not available on non-windows system, most notably linux. Since there is an obvious absence of this functionality I can only assume there is a good reason which I am blind to, but in my primitive understanding I simply see the DirectX calls as no more than function entry points on the hardware device. And for the record I am not referring to a compatibility layer (most notably WINE, a project I am amazed by every single day) but a library making

everybody, I have the following problem: I started a P2 instance with this AMI . I installed some tools like screen, torch, etc. Then I successfully run some experiments using GPU and I created an image of the instance, so that I can terminate it and run it again later. Later I started a new instance from the AMI I created before. Everything looked fine - screen, torch, my experiments were present on the system, but I couldn't run the same experiments as before: NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed

Does anybody know how to control USB pins on a certain USB port? I think it is definately possible in assembler but what about C++ or C#? I want to be able to use USB battery as a power supply for an LED or something like that. So then a program would power it on and power it off making it flash. I know it sounds pointless but I need to do it for something awesome. I also know that it might require a custom driver. USB is not trivial, so I guess you'll have some problems (mis)using it. You would be /much/ better off (IMHO) with standard serial ports, which have been used for stuff like that

I work for a company that sells USB devices and provides drivers for them. In Windows 7, you could install and use unsigned INF driver files for USB devices as long as they didn't add any code to the kernel. Our company uses generic drivers provided by Microsoft ( usbser.sys and winusb.sys ), so we never needed to sign our driver packages. Based on a report from one of our customers and from another Stack Overflow question What changed in the driver signature requirements for Windows 8? and the Arduino forum , it sounds like the Windows 8 Consumer Preview has stricter signing requirements that

I am a newbie learning how to write WDM device drivers for USB devices and found that the materials available are all too hard to comprehend (the DDK online doc is one of the most difficult to read, and the WDM Device driver book by Oney isn't anything better). So, I've got a simple question. Where do I start if I want to create a virtual USB device (for example, a virtual USB mouse which looks like a real USB mouse attached to a USB port) for testing/learning. So far what I understand is the HIDClass driver (hidclass.sys) has a minidriver for the usb bus (hidusb.sys) that carries out the
