config usb_storage_sddr55
bool sandisk sddr-55 smartmedia support (experimental)
depends on usb_storage && experimental
help
say y here to include additional code to support the sandisk sddr-55
smartmedia reader in the usb mass storage driver.
很显然这个选项是有关sandisk产品的&＃xff0c;并且针对的是sm卡&＃xff0c;同样不是u盘&＃xff0c;所以我们也不需要去关注。
事实上&＃xff0c;很容易确定&＃xff0c;只有选项config_usb_storage才是我们真正需要关注的。

13 say y here if you want to connect usb mass storage devices to your
15 floppy drives, usb hard disks, usb tape drives, usb cd-roms,
16 usb flash devices, and memory sticks, along with
17 similar devices. this driver may also be used for some cameras
18 and card readers.

20 this option depends on scsi support being enabled, but you
21 probably also need scsi device support: scsi disk support
22 (blk_dev_sd) for most usb storage devices.
