Editable Acroname device name – click the pencil icon to change the friendly name, click device save to store the change to the device internal memory. Default – product family name

Serial number – unique to the Acroname device

Upstream port selection – select Fixed, Port Priority (lowest port number has priority), or Last Connected to control how the upstream (host-facing) port is assigned. In fixed mode, the upstream port can be selected directly by clicking the dark blue port name buttons

Editable Port name – name of Acroname device port. Click the pencil icon next to Acroname device name to edit, click device save to store the change to the device internal memory. Default – numerical value of port

Device class icon – unique for each standard USB device class, e.g., mass storage, HID, imaging. If a device is not recognized as a standard class, it will appear as a question mark.

Port toggle – independently enables and disables each port. Up = on

USB device speed – nominal device connection speed

USB MFG / device name – manufacturer and device name descriptors

Device save – stores changes to the hub friendly name and port enabled / disabled toggles. Saved changes will persist through power cycles

Device reset – reboots the Acroname device, temporarily disconnecting and reconnecting all connected USB devices

The port control panel adds detailed extension link quality information when a pair of USBExt3c are connected:

  • Cable Length (m)

  • Mean Squared Error (pairs 1-2 and 3-4, dB)

    • -10 dB: recommended maximum error

    • -14 dB: nominal

    • ~ -20 dB: ideal

  • Link Utilization (%)

  • Encoding

  • Retransmission rate (# messages between retransmissions, 0 = no errors)

    • Should be zero in normal operation. Non-zero indicates retransmissions and a problem with the link such as exceeded maximum link length or an issue with the cable or connectors.
