USB 2 4-port hub current output

Does the USB 2 4-port hub supply 1500mA to a port, subject to the 2.5A limit, without any connections to the data or id lines? That is, a type A connector with V+ and GND and no other connections can draw up to 1500mA?

Thanks for asking!

If you hook a device that only uses V+ and GND for charging without negotiation (a “dumb” charger), it will pull up to the maximum allowed on the port up until over-current protection trips.
