USB hub testing with MUTT devices

The goal of hub testing is to generate a complete set of possible traffic patterns from devices. You can test disconnect scenarios by adding an upstream SuperMUTT pack.

Hub testing prerequisites

Before you run the MUTT test commands at an elevated command prompt, make sure you meet the following requirements:

Recommended hub tests

Recommended topologies for hub testing with MUTT devices

  • Attach MUTT devices to each available downstream port.
  • Attach SuperMUTTs to half of the available ports. Attach MUTT devices to the remaining ports.
  • Attach a SuperMutt Pack upstream of the hub under test and downstream ports have equal number of SuperMUTT and MUTT devices as shown in the following figure:
