the Vendor of the user device (assigned by USB-Interface Forum).
04h
22h Product ID LSB Register (PIDL)
Least Significant Byte of the Product ID. This is a 16-bit value that the Vendor can
assign that uniquely identifies this particular product (assigned by the OEM).
14h
23h Product ID MSB Register (PIDM)
Most Significant Byte of the Product ID. This is a 16-bit value that the Vendor can
assign that uniquely identifies this particular product (assigned by the OEM).
95h
24h Device ID LSB Register (DIDL)
Least Significant Byte of the Device ID. This is a 16-bit device release number in
BCD format (assigned by the OEM).
00h
25h Device ID MSB Register (DIDM)
Most Significant Byte of the Device ID. This is a 16-bit device release number in BCD
format (assigned by the OEM).

26h Config Data Byte 1 Register (CFG1)
Refer to Table 3-4, “Config Data Byte 1 Register (CFG1) Format,” on page 28 for
details.
9Bh
27h Config Data Byte 2 Register (CFG2)
Refer to Table 3-5, “Config Data Byte 2 Register (CFG2) Format,” on page 29 for
details.
18h
28h Config Data Byte 3 Register (CFG3)
Refer to Table 3-6, “Config Data Byte 3 Register (CFG3) Format,” on page 29 for
details.
00h
29h 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.
