Non-Removable Devices Register (NRD)

Indicates which port(s) include non-removable devices.

0 = Port is removable

1 = Port is non-removable

Informs the host if one of the active ports has a permanent device that is not

detachable from the Hub.

Note:

The device must provide its own descriptor data.

Bit 7 = RESERVED

Bit 6 = RESERVED

Bit 5 = 1; Port 5 non-removable

Bit 4 = 1; Port 4 non-removable

Bit 3 = 1; Port 3 non-removable

Bit 2 = 1; Port 2 non-removable

Bit 1 = 1; Port 1 non-removable

Bit 0 is RESERVED, always = 0b

Note:

Bit 1 must be set to 1 by firmware for proper identification of the Ethernet

Controller as a non-removable device.
