4.4.17 POWER-ON TIME REGISTER (PWRT)
4.4.18 LANGUAGE ID HIGH REGISTER (LANGIDH)
4.4.19 LANGUAGE ID LOW REGISTER (LANGIDL)
4.4.20 MANUFACTURER STRING LENGTH REGISTER (MFRSL)
Address: 0Fh Size: 8 bits
Bits Description Type Default
7:0 Hub Controller Max Power Bus-Powered (MAX_PWR_BP)
Value in 2mA increments that the Hub consumes from an upstream port
(VBUS) when operating as a bus- powered hub. This value will include the
hub silicon along with the combined power consumption (from VBUS) of all
associated circuitry on the board. This value will NOT include the power
consumption of a permanently attached peripheral if the hub is configured as
a compound device.
R/W 00h
Address: 10h Size: 8 bits
Bits Description Type Default
7:0 Power-On Time (POWER_ON_TIME)
The length of time that is takes (in 2 ms intervals) from the time the host
initiated power-on sequence begins on a port until power is good on that
port. System software uses this value to determine how long to wait before
accessing a powered-on port.
R/W 00h
Address: 11h Size: 8 bits
Bits Description Type Default
7:0 USB Language ID High (LANG_ID_H)
Upper 8 bits of the 16-bit language ID field.
R/W 00h
Address: 12h Size: 8 bits
Bits Description Type Default
7:0 USB Language ID Low (LANG_ID_L)
Lower 8 bits of the 16-bit language ID field.
R/W 00h
Address: 13h Size: 8 bits
Bits Description Type Default
7:0 Manufacturer String Length (MFR_STR_LEN)
Maximum string length is 31 characters.
