The replacement is `embassy-usb`. There's a WIP driver for stm32 USBD in #709, there's no WIP driver for stm32 USB_OTG. This means we're left without USB_OTG support for now. Reason for removing is I'm going to soon remove `embassy::io`, and USB uses it. I don't want to spend time maintaining "dead" code that is going to be removed. Volunteers welcome, either to update old USB to the new IO, or write a USB_OTG driver fo the new USB.
