Strip the machine down to nothing but a poser supply, motherboard, CPU, RAM and video card. Try to power it up. If you still get nothing, you've got major problems. You'll be swapping these parts out one-by-one, starting with the power supply, until you find the part(s) that is(are) failing.

Just buy a new system. The way you're asking the question implies you don't have the knowledge to fix it.

There is no Pentium 5. After the Pentium 4, Intel did a ~~complete~~ redesign of their microarchitecture and developed the "Core" series which is what the Core Duo and Core 2 Duo processors are based on. The Pentium line is dead.

It's not a complete redesign. The Core series is derived from the Pentium-M which is an enhanced P3 design.

Generic USB access

Hey all,

I have several projects that I want to complete that involve USB devices. I was wondering if there is any generic way to grab the output and input to any USB device.

I'm not looking for anything too clean, just something that works for the moment, as I will spend time adjusting the method to my various projects.

At any rate, is there a generic way to access the output and input of any USB device in windows? (or even just grab the output?)

thanks,

No, there isn't. USB is not a port, like serial or parallel. It's a BUS, just like the PCI bus you stuff cards into inside the machine. Communicating with any device on the bus requires you to go through the interface supplied by the drivers for that device.

Oh, Ok, thanks for explaining that, makes since now. Always wondered why USB was so different.

I have a couple of USB boxes which support performing digital and analogue I/O.

They didn't come with drivers (and as I run FILEMON when I install stuff, I can be reasonably sure of that!). However, there is an API library supplied to communicate with the hardware.
Presumably this uses a standard MS-supplied driver to provide user-mode access to allow tx/rx of requests/replies sent to the devices?

You need the documentation on that SDK, otherwise, it's useless. That SDK is your only method of communication with the devices.

I appreciate that (and I have, and use, the documentation), but my point is that it must be using some user-level mechanism which does not depend on a manufacturer-specific driver, instead using some generic way of communication. My next obvious step would be to run Depends on the supplied DLL, and see what it loads that I don't recognise.

That's what the device's SDK is for. There are no "generic" communication methods with any USB devices.

Depends can tell you what functions a .DLL exports and will give you the function names, but it can NOT give you the number of parameters and the data types of those parameters. The only thing that can give you that is the docs on the SDK.

Very true, and in this case, since it also gives the names of functions that the DLL imports, it can tell you that it's using SETUPAPI functions, and functions from HID. The latter is what the library appears to be using for communication. However, we're now well off the original poster's track, although I may come back at a much later date with an article on how the supplied DLL does it's USB communication without a specific device driver Smile | :)

Sure, with the SETUPAPI, a bunch of DeviceIo calls, and the documentation on what the device's commands and responses are. It's generic, but only to a point. Eventually, you have to get into the specifics of the device.

Is this a windows supplied API? or did it come with the devices?

Also, is there documentation for it?

thanks

It came with the device, and comes with documentation on it, but not how the underlying DLL itself works.

Alright, all you indian guys listen-the-f***-up. If you need drivers for your machine, YOU HAVE TO KNOW SPECIFICS. Chances are that you will need to know the brand and model number of your MOTHERBOARD, especially if you have onboard hardware like sound cards, video, and ethernet. Once you find out what motherboard you have, chances are pretty good that you'll be able to use google to find your drivers.
