Ah yes, so this is the "UDC" controller in the Aspeed SoC. Those SoC
act as BMC in a lot of server platforms.

The UDC is a bit special as it simulates a hub with up to 5 devices
behind it. So I need to make up descriptors for the hub portion of it.

It's thus sort-of a virtual gadget hub.

I think it's probably ok to use the same product ID for the USB1 and
the USB2 mode with a different speed, so one should be enough.

Thanks !

Cheers,
Ben.
