Autodisabled Ports
The Express 130T Standalone Hub automatically disables a port when
it detects a serious error on that port, such as a series of more than 64
collisions on a single packet. Once the hub sees a valid packet from the
device or is able to transmit a packet from the port, it automatically
reenables the port. Connected devices aren't usually affected by an
autodisabled port because the port is reenabled so quickly.
If a port remains autodisabled, check the connected device's network
adapter and cabling, or unplug the network cable for a few seconds,
then reattach it.
