The NI USB-6501 is a digital IO module for USB from National Instruments.Unfortunately, their driver for Linux is excessively large ( 60M!) anddidn't work. So we decided to analyze the USB protocol and write our owndriver.The result can be found in the directory c/.For further details, have a look at doc/documentation.html.NI USB-6218 is also a digital IO module for USB, it shared the command structureof the NI USB-6501, however it is based on FPGA module which need to be programmedbefore every use.Once started it will listen in 'bootloader' mode, and after programming it willshut down USB and reconnect as the USB-6218 module.

Hello, I discovered that I need Data Acquisition Toolbox to send triggers to an NI USB-6501 device. However, I'm using a Mac. Is there an alternative to the Data Acquisition Toolbox that works on Macs and will allow me to communicate with this device, or do I need a Windows machine? Praveen kumar actor movies.
