What do you mean? Everything is capable of enumeration! "That's one USB power supply!" >:D

I used to run a shorting wire from the four USB sockets to the regular 5V.
Then I could feed the power in on a USB A plug instead of the wimpy micro USB.

metebalci:
Not an expert, but I take it to mean no other/some more/normal USB signalling. No handshake, negotiation etc.

Renate:
Oh, yeah, I get USB enumeration and low-level USB.
I guess that you're not familiar with Count von Count from Sesame Street.
He likes to count things.
