happy easter all;
lets say a USB2.0 hub is connected to a host , with many high-, full- and
low-speed devices connected to it.

devices.

speed hub?
No, a high speed host communicates with a high speed device at high speed.
The hub is a high speed device.
> if not how does the hub knows which packet is should go to which device?
Uh. The device address?
