USB-6501 driver issues with NiDAQmx

[dabulldog26]

I have the same issue as well, and am in the process of Repairing Ni-Max.  Going to see if that will make a difference.

I have the same issue with USB 6501 OEM. First it worked briefly and now it is stucked in usb firmware loader.

How come there seems to be no real fix for this? It clearly is SW issue that National Instruments should address.

Has anyone found simple fix for this? Or is there DAQmx version that works? Seems like the non OEM version works just fine.

I had the same issue. I tried multiple devices, uninstalling Daqmx, reinstalling, updating to 2023Q4, forcing the usb-6501 driver, updating USB 3.0 drivers, and much more. Nothing worked.  Finally, with the non functional Daqmx 2023Q4 already installed, I tried installing the DaqExpress 5.1 application and bam. It just worked. Comes up as 6501 device, no communication errors, led flashes, and I can now control it.

Same issue here. First encountered on a machine with DAQmx 23 and only USB3.0 ports. Google led me to this article: NI MAX Not Recognizing USB DAQ Device When Connected Through USB 3.0 - NI 

Figuring it might be a USB3 issue, I plugged the board into a USB2.0 slot on a different machine that happened to be running DAQmx 22.5. At first the board appeared to have the same issue, but I ignored it for a bit while I did more searching. When I came back to it, it must have updated itself and is now working as expected on both machines.

I had 2 other boards that appeared in the USB3 machine's Device Manager, but NI-Max still showed errors. When I plugged the board into the USB2.0 machine, device manager detected the hardware change, but no devices showed up in the device tree or in NI Max. However, upon restarting the computer, the board presented itself as an unknown device. I manually updated the driver through device manager to USB-6501 and the board started working as expected on both machines. I had to repeat this whole process for the 2nd board as well.   

In addition, a colleague found that newer boards aren't presenting this issue. As a proxy for a date code, the serial number for problem boards (converted to decimal for folks who don't speak native hex 😀) were between 20,000,000 and 24,000,000. The newer boards had serial numbers around 34,000,000.

I found another post in Digital I/O with what appears to be the same issue. Another suggestion that appears relevant is this article: DAQ Device Shows up as USB Flash Firmware Loader in Device Manager - NI

This worked for me too. I had issues with two USB-6001 working flawlessly on PC1 with an older version of NIMax but showing as a USB Flash Firmware Loader on PC2 with a newer version of NiMax.

It worked only once. Back to initial issue after disconnecting and reconnecting the 6001.
