High speed ADC data acquisition over USB and into Labview

I need to design a device that will use an external 16-bit ADC, 8 or 16 channels, at 10Ksps per channel, total data rate up to 320Kbytes/sec. I want the data fed into Labview just like one of National Instruments' DAQ devices would do. I've done many projects using a serial to USB converter but this project demands much faster throughput than 115200 baud. I've not worked with USB at this level before. NI says their VISA library supports USB devices as Test and Measurement Class (USBTMC) or USB RAW instruments. I need a library to run on the Teensy and make it appear as a TMC device. I've done some searching but haven't come across any. I use Teensy 3.2 extensively but am not familiar with the newer 3.x and 4.x models and what they support in the way of USB. Thanks in advance,
