Connecting multiple DAQs into the same computer

Hi, 

Im working in a project where i wil need to connect more than 300 digital signs with a USB port.

I was looking for options, and found two that i liked, but i dont know if LabView will have troubles reading all the signs from different DAQs.

My first option is the USB-6501 (with 24 digital I/O), where Ill start doing the config, but if it works for what im looking for, i was expecting to repeat the same config in a total of 13 DAQs

My second option was, the High-Density Industrial I/O for USB (96 channels digital), and have in total 3 DAQs with an extra of the USB-6501 to complete my set of signals.

Can I connect more than one DAQs into the same computer? Meaning that all the DAQs will be working into the same LabView app?

Regards,
