|
- manufacturer : Set USB Manufacturer string (max 31 characters long)
|
|
- product : Set USB Product string (max 31 characters long)
|
|
- serial : Set USB Serial string (max 31 characters long)
|
|
- {bus,self}-powered : selects between self- and bus-powered operation

|
|
operation if the local power source is removed or unavailable (boolean)
|
|
- oc-delay-us : Delay time (in microseconds) for filtering the over-current
|
|
sense inputs. Valid values are 100, 4000, 8000 (default) and 16000. If
|
|
an invalid value is given, the default is used instead.

|
- compound-device : indicate the hub is part of a compound device (boolean)
|
|
- port-mapping-mode : enable port mapping mode (boolean)
|
|
- led-{usb,speed}-mode : led usb/speed indication mode selection
|
|

silicon along with all associated circuitry excluding a permanently
|
|
attached peripheral (range: 0 - 100000 uA, default 1000 uA)
|
|
