Parameters

[in]	usbd_dev	The USB device to associate the Mass Storage with.
[in]	ep_in	The USB 'IN' endpoint.
[in]	ep_in_size	The maximum endpoint size. Valid values: 8, 16, 32 or 64
[in]	ep_out	The USB 'OUT' endpoint.
[in]	ep_out_size	The maximum endpoint size. Valid values: 8, 16, 32 or 64
[in]	vendor_id	The SCSI vendor ID to return. Maximum used length is 8.
[in]	product_id	The SCSI product ID to return. Maximum used length is 16.
[in]	product_revision_level	The SCSI product revision level to return. Maximum used length is 4.
[in]	block_count	The number of 512-byte blocks available.
[in]	read_block	The function called when the host requests to read a LBA block. Must NOT be NULL.
[in]	write_block	The function called when the host requests to write a LBA block. Must NOT be NULL.

Returns
