7:0 | MAX_PWR_SP | Max Power Self_Powered: Value in 2mA increments that the Hub consumes |
|
| from an upstream port (VBUS) when operating as a |
|
| value includes the hub silicon along with the combined power consumption |
|
| (from VBUS) of all associated circuitry on the board. This value also includes |
|
| the power consumption of a permanently attached peripheral if the hub is |
|
| configured as a compound device, and the embedded peripheral reports |
|
| 0mA in its descriptors. |
|
| Note: The USB 2.0 Specification does not permit this value to exceed |
|
| 100mA |
|
| A value of 50 (decimal) indicates 100mA. |
