Hi experts,

I'm a usb hub system developer and I am using usb hub EVB from Microchip. I found there is a USB2 Controller hub device listed in a removal list on system tray. And when I remove it by clicking "eject USB2 Controller hub" option, the USB2 hub is gone whereas its USB3 hub is still working. Another hub (use different chip vendor) however is not in the system tray, I was wondering what kinds of device class will appear in the system tray.
At first, I thought only media devices (like ipod) or mass storage devices will appear in the safe removal list, but the hub from Microchip actually attaches a generic usb class, non-removable device at last port, and this device also appears in the removal list.

Any comment is appreciated!
