: The name array passed to the USB core.
: Set if the endpoint has been halted. : Set if this is a periodic ep, such as Interrupt : Set if we've sent a zero-length packet. : The total number of data bytes done. : The size of the FIFO (for periodic IN endpoints) : The amount of data loaded into the FIFO (periodic IN) : The offset of data for the last start of request. : The last loaded size for DxEPTSIZE for periodic IN This is the driver's state for each registered enpoint, allowing it to keep track of transactions that need doing. Each endpoint has a lock to protect the state, to try and avoid using an overall lock for the host controller as much as possible. For periodic IN endpoints, we have fifo_size and fifo_load to try and keep track of the amount of data in the periodic FIFO for each of these as we don't have a status register that tells us how much is in each of them. (note, this may actually be useless information as in shared-fifo mode periodic in acts like a single-frame packet buffer than a fifo)
