Upgrade Guidelines for Existing USB-Cascading Chains

Firmware version 3.3.10 is NOT compatible with old firmware
versions in terms of the USB-cascading feature so all devices in a
chain must be running version 3.3.10 or later. Otherwise, a
networking issue occurs.
Alternative: You can also choose to have an existing USB-cascading
chain keep on running the old firmware without upgrading any device
to 3.3.10 or later.

When upgrading an existing USB-cascading chain from any version
prior to 3.3.10, the upgrade must start from the last slave device,
then the second to last, the third to last, and so on until the master
device. Any upgrade without following this sequence results in the
networking failure of some cascaded devices.
