While switching from bus-powered to self-powered operation does not necessarily require immediate renegotiations with the host, switching from self-powered to bus-powered operation may cause USB connections to be reset if connected devices previously requested more power than still available in bus-powered mode. In contrast, a self-powered hub is one that takes its power from an external power supply unit and can therefore provide full power up to mA to every port. Some models, however, have the ability to control multiple peripherals separately e. VanessaET Created on March 14, In particular, if a downstream port of a hub changes status, this change is dealt with in an interaction between the host and this hub; the hubs between them act as transparent in this case. However, many devices require more power than this method can provide and will not work in this type of hub.

How satisfied are you with this reply? They can either be manual, effectively a simple switch-box, or automatic, incorporating a mechanism that recognises which PC wishes to use the peripheral and switches accordingly.
