This really isn't that big of a deal. Just check all your usb cables and ports to make sure there are no pieces of metal within the ports and cable connectors which is most likely the cause of the power surge.
Sometimes USB devices will display a warning that they have exceeded the power limits of the hub port. This means that the port cannot keep up with the power demands of the device. To fix the problem, either switch ports, or connect the device to an outlet cord.
Port in hub/switch refers to the interface where you connect your computers.
If you connecting a hub to another device then the cable must be placed in the uplink port, or a port that can switch between a client port and an uplink port.
The "Crossover" port. (or MDI-X)
There are no charge to recylce a 24 port ethernet hub.
Powerdsine 12 Port Power Over Ethernet Hub is reasonable priced and is capable of connecting to 12 different computers, the next alternative is the HP 12 Port FiberChannel Hub which can also connect 12 machines, just not over ethernet.
that's a power surge, happens to me some times, i just plug the usb on other slot or turn on the computer with the iPod already plugged in
The portable printer requires more power than is available through a USB hub
Hub
A hub resends the signal it receives out through all ports, except the port where it received it.A hub resends the signal it receives out through all ports, except the port where it received it.A hub resends the signal it receives out through all ports, except the port where it received it.A hub resends the signal it receives out through all ports, except the port where it received it.
In regards to the average usb port hub and how many ports are available, this can vary. The average usb port hub can support up to four usb inputs at a time.
I don't think it has to be anymore than 2, but it can be quite a few. The problem with a hub say for a computer like a usb hub is that each device receives less power and they are all sharing the same port, its like hooking 5 computers to one modem.
