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.

sound drivers for intel pentium 3 processor,800MHz

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.

WE CANNOT HELP YOU BECAUSE WE DON'T KNOW THE INFORMATION I DESCRIBED ABOVE, SO STOP ASKING.

No, because a processor does not dictate the drivers to use. The sound card in your machine does. Without knowing that, your guess is as good as ours.

The sound card can be just that, a seperate card you have to plug into a slot, or it can be built onto the motherboard, in which case, you'll have to get out the manual on it or consult the manufacturers website for the specs on the sound chip being used.

please let us know the details of the make of your motherboard as well if it is having built in or additional Sound Card. Please stop making a fool of yourself by posting half cooked informations.

please checkout what he has written in the thread below which is just a few above yours...

Please have some common sense. Nobody here would be able to assume the details on their own. you must give them by yourselves. and one more thing. Do some homework atleast before coming here. Google the problem first then resort to us.

Do u still have the manual to the mobo? It might tell the Key combination to load up BIOS beside the Del key. Does Windows still boot up? Do u see anything on the screen. I would check all these things.

Hello.

I'm trying to figure out how to determine on which disk is Windows installed. I need to do this so that I can get additional infos afterwards about it, like Model Number, Serial Number, etc.

I don't need the partition letter (C:, etc), that's easy to get, but on which disk that partition is located (Primary Master (\\.\PhysicalDrive0), Primary Slave (\\.\PhysicalDrive1), etc).
Also, I don't want to use WMI.

Any help is greatly appreciated. Thanks alot.

Hi,

Anyone have any idea where I can find these monitors. I am looking for these kind for a long time, but none of them are VGA compatible (only RCA). I want a VGA display anywhere between 3" to 4.5" LCD.

thanks,

THanks for the info. I have seen those lilliput "monitors", their size is perfect for my applicaiton, but I need a VGA monitor while lilliput has RCA monitors...I need something that we can just plug into the VGA output of PC/Laptop or even to USB/Firwire output like the ones dontronics has, but the resolution is not that great for dontronics.

Can't you just add a VGC-RCA adapter to your hardware design?

Yeh.... thts not at all a prob for me... but my Boss likes just plug 'n play and not to hassle around with the extra stuff to carry along.... He believes someone somewhere should have made such kind of VGA monitors as he is seeing all those high resolution TFT LCDs tht we get in new mobile phones (ofcourse they are not VGA type).
