RedLab 1024HLS and possibly the computer. Once you start running applications with the RedLab 1024HLS, each DIO bit can draw up to 15 mA. The maximum amount of +5 V current available for external use, over and above that required by the RedLab 1024HLS, is the difference between the total current requirement of the RedLab 1024HLS (based on the application), and the allowed current draw of the computer platform. -

Output (sink) current limits Each RedLab 1024HLS DIO output can sink up to 64 mA. For an individual line, this is not a problem. But if you were to apply this maximum load to all 24 DIO lines, you may damage the RedLab 1024HLS because the total amount of current is well over the maximum for the USB supply. - Page 17 RedLab 1024HLS User's Guide Functional Details To configure a pull-up connection for a specific port, wire the pull-up/pull-down terminal to a USB +5 V terminal.

If your laptop is constrained to the 100 mA maximum a RedLab 1024HLS is not guaranteed to work. In order to use the product you will need to purchase a self-powered hub. -
Page 20: Counter Section
Bus-powered hubs are allowed to provide downstream USB power as low as 4.4 V. Although your Note 6: RedLab 1024HLS will typically function at this 4.4 V minimum, guaranteed performance requires a minimum power supply voltage of 4.75 V. All self-powered and root port hubs will meet this 4.75 V minimum. -
