USB Enumeration

[yas745]

Hello,

Would it be possible to conduct enumeration when connecting to devices like PCs, smartphones, and so on?

For example, would it be possible to obtain information about the suppliable current of the connected devices?

Hi,

 

The field bMaxPower in the descriptor describes how much current you will draw when in configured USB state.

You can read more about this field here: https://www.beyondlogic.org/usbnutshell/usb5.shtml

 

Kind regards,
