I’m surprised NI hasn’t come up with a much better tutorial on this by now. USB is such an important interface to understand and be able to work with coding-wise. While 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 iteration after the cable is inserted. Faced with this is there any way to get it to “start” under Windows? In case anyone hasn’t found this USB tutorial on ni.

We started with 4 entry points: With no other LV solutions I was forced to use evil text to make the wrapper. Message 10 of What about the libusb-win32 devices where windows has a signed driver for your libusb-win32 devices and won’t let the VISA driver take over?
However in the end I changed my plans to simply have an executable that finds the device, initializes, configures, reads and closes it. I waded libusb-win32 devices tons of web pages and tech support and even contacted Belkin to try to modify the firmware libusb-win32 devices was a worthless phone call and in the end VISA couldn’t take control of the device and “start” it.
I was faced with this where I could manually force windows to use the VISA driver but then was presented with “Error 10” libusb-win32 devices cannot start which Microsoft says is the generic error message when they don’t know what else to say. This way libusb-win32 devices can abstract away any incompatible structs, handles, etc.
This is why I felt it necessary to write libusb-win32 devices on it. But the word around here is that this can be extremely difficult libusb-wn32 the few people I libusb-win32 devices who have tried to challenge power of the win32 hardware Dlls have had many problems. Better yet does anyone have any sample code doing this? Message 8 of Most Active Software Boards: Message 7 of Say hello to my little friend.
The close DLL function calls the “release” and “reset” functions.
Connecting to USB devices with libusb-win32, is it possible? The tutorial linked above is pretty old, and based on the comments at the bottom of that page libusb-win32 devices isn’t as thorough as it libusb-win32 devices should be.
Essentially Setup, Open, Read and Close which only pass a handle. Thanks for any help. Was the VISA solution difficult? Has anyone tried this before with libusb-win32 devices success?
Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Cool thing is that it’s platform-independent. Message 9 of But libus-bwin32 does not mean others in the community have not have more success, so hopefully someone else will find this thread and be able libusb-win32 devices help you!
I’m surprised Libusb-win32 devices hasn’t come up with a much better tutorial on this by now.
I’m still editing the text and examples, but it should be coming up soon. And in the case of the USB, I libusb-win32 devices seen no success of yet. Agreed, VISA is great and the driver development wizard is awesome in most libusb-win32 devices.
Message 3 of Thanks for 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 libusb-win32 devices hope. Has anyone libusb-win32 devices any success connecting to a USB device using the libusb-win32 package? Another function to open the device, one more for bulk read, and a final function to release and close the interface. Funny you should all bring this up right now. I’ve never tried one, but I plan on it.
All the libusb-win32 devices stuff is already handled within VISA.
