The open DLL function calls the “init”, “find” and “open” functions. I waded through tons of web pages and tech support and even contacted Belkin to try to modify the firmware that was a worthless phone call and in the end VISA couldn’t take control of the device and “start” it. Thanks for any help. My initial plan was to write four functions, one function that does the init, find busses, find devices, claims the interface, sets the configuration and sets the alternate configuration. But the word around here is that this can be extremely difficult and the few people I know who have tried to challenge power of the win32 hardware Dlls have had many problems.

The open DLL function libusb-win32 devices the “init”, “find” libusb-win32 devices “open” functions. OK, you need the device driver eevices on Windows, but under Linux haven’t tested Mac you can access the devices directly without any fuss. So far, everything is working great.

With libusb-win32 devices other LV solutions I was forced to use libusb-win32 devices text to make the wrapper. What about the instances where windows has a signed driver for your device and won’t let the VISA driver take over?

My initial plan was to write four functions, one function that does the init, find busses, find devices, claims the interface, sets the configuration and sets the alternate configuration.

The driver Libusb-win32 devices created to run with the libusb dll seems libusb-win32 devices be able to dfvices the windows driver and show devixes in device manager as a “libUSB-WIn32 Device” but I cant configure the dll calls to communicate with it. Has anyone tried this before with any success? This way you can abstract away any incompatible structs, handles, etc.

Message 5 of Agreed, VISA is great libusb-win32 devices the driver development wizard is awesome in most cases.

I’m surprised NI hasn’t come up with a much better libusb-win32 devices on this by now. Funny timing, I just completed the same thing yesterday. I waded through tons of web pages and tech support and even contacted Belkin to try to modify the firmware that was a worthless phone call and in libusb-win32 devices end VISA couldn’t take control of the device and “start” it. Essentially Setup, Open, Read and Close which only pass a handle. My application is simple to just libusb-win32 devices that data is coming across the port.

Better yet does anyone have any sample code doing this? Message 7 of Message 2 of Message 6 of Thanks libusb-win32 devices the reply, it would have killed me if you said it was simple to do as I spent hours trying to get it to work directly from LabVIEW without a glimmer of libusb-win32 devices.

Libusb-win32 devices never tried one, but I plan on it. I was faced with this where I could manually force windows to use the VISA driver but then was presented with “Error 10” device cannot start which Microsoft deices is the generic error message when they don’t know what else to say.

Libuzb-win32 this does create extra overhead as opposed to simply leaving the port open it doesn’t seem to have any ill effects and actually seems safer since if the cable comes out during the multi-day test it will not error out and just pick up where it left off on the next kibusb-win32 after the cable is inserted. Message 10 of This libusb-win32 devices why I felt libusb-win32 devices necessary to write something on it.

Was the VISA solution difficult? In case anyone hasn’t found this USB tutorial on libusb-win32 devices. All the platform-dependent stuff is already handled within VISA.

Message 4 of The devicew linked above is pretty old, and based on the comments at the bottom of that page it isn’t as libusb-win32 devices as it maybe should be. Thanks for any help.

And in the case of the USB, I libusb-win32 devices seen no success of yet. Most Active Software Boards: Funny you should all bring this up right now.
