The new USB-TCO1 features the following:
want to use NI-DAQmx to log data from two or more of these as a multi-channel device. Can it be done?
If not, is there a USB version of multi-channel device that would work with NI-DAQmx?
No, unfortunately you can not have a multi-device task in NI-DAQmx with the USB-TC01. One good bed, since you need USB, would be to use something like the cDAQ-9171 and a thermocouple module like the NI 9213. You can find such a bundle here.
