PSU for NEWLink 4Port USB

[Tony]

Can someone help, I have mislaid the power supply unit for my NEWLink 4Port USB2 Hub model NET4006. Can some please tell me the current/voltage specification needed.

Thanks,
Tony.

Often the power requirement is right next to the input
socket. Being a USB2 hub, I'd expect it needs 5V, and 500mA
per port pair plus a few dozen mA (if that) for the device
itself. This is assuming it's supposed to be a "powered"
hub in that it supplies the power for the connected USB
devices. So, being a 4 Port hub I'd expect you need at
least 1A, 5V... ideally slightly more than 1A, 5V, regulated
type (linear or switching, not just a cheapo unregulated
wall-wart type of transformer plus rectifier + misc.). How
to tell? If it's regulated it should already be at (very
near) the correct voltage when it's not powering anything.
The cheap unregulated type will float to a value
significantly higher than 5.0V.
