+ tristate "USB ENE SM card reader support"
+ depends on USB && SCSI && m
+ ---help---
+ Say Y here if you wish to control a ENE SM Card reader.
+ To use SD/MS card, please build driver/usb/storage/ums-eneub6250.ko
+
+ This option depends on 'SCSI' support being enabled, but you
+ probably also need 'SCSI device support: SCSI disk support'
+ (BLK_DEV_SD) for most USB storage devices.
+
+ To compile this driver as a module, choose M here: the
+ module will be called keucr.
