What issues could be caused by the use of USB 3.0 that will impact your site survey?

When surveying an existing WLAN infrastructure for a possible redesign, you use two Wi-Fi USB adapters to collect RSSI data and two USB spectrum analysis adapters to collect RF spectrum data. Since your laptop doesn’t have enough USB ports, you use a 4-port powered USB 3.0 hub.
