# # USB Storage driver configuration # comment "NOTE: USB_STORAGE enables SCSI, and 'SCSI disk support' may also be needed; see USB_STORAGE Help for more information" config USB_STORAGE tristate "USB Mass Storage support" depends on USB select SCSI ---help--- Say Y here if you want to connect USB mass storage devices to your computer's USB port. This is the driver you need for USB floppy drives, USB hard disks, USB tape drives, USB CD-ROMs, USB flash devices, and memory sticks, along with similar devices. This driver may also be used for some cameras and card readers. This option 'selects' (turns on, enables) 'SCSI', 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 usb-storage. config USB_STORAGE_DEBUG bool "USB Mass Storage verbose debug" depends on USB_STORAGE help Say Y here in order to have the USB Mass Storage code generate verbose debugging messages. config USB_STORAGE_RW_DETECT bool "USB Mass Storage Write-Protected Media Detection (EXPERIMENTAL)" depends on USB_STORAGE && EXPERIMENTAL help Say Y here in order to have the USB Mass Storage code indicate to the SCSI layer that using MODE SENSE(6) and MODE SENSE(10) to determine if the media is write-protected is a good thing to do. Many devices have historically had trouble with these commands, hence the default 2.6.x behavior has been to suppress their use. 2.4.x used these commands with (at best) mixed results, often crashing the firmware of the device. However, the SCSI layer now issues these commands in a manner more consistent with other "popular" OSes, in an attempt to improve compatibility. Saying Y here allows these commands to be sent to a USB device. If you find a device this doesn't work for, switch to N and let us know at If you say N here, the kernel will assume that all disk-like USB devices are write-enabled. config USB_STORAGE_DATAFAB bool "Datafab Compact Flash Reader support (EXPERIMENTAL)" depends on USB_STORAGE && EXPERIMENTAL help Support for certain Datafab CompactFlash readers. Datafab has a web page at . config USB_STORAGE_FREECOM bool "Freecom USB/ATAPI Bridge support" depends on USB_STORAGE help Support for the Freecom USB to IDE/ATAPI adaptor. Freecom has a web page at . config USB_STORAGE_ISD200 bool "ISD-200 USB/ATA Bridge support" depends on USB_STORAGE && BLK_DEV_IDE ---help--- Say Y here if you want to use USB Mass Store devices based on the In-Systems Design ISD-200 USB/ATA bridge. Some of the products that use this chip are: - Archos Jukebox 6000 - ISD SmartCable for Storage - Taiwan Skymaster CD530U/DEL-0241 IDE bridge - Sony CRX10U CD-R/RW drive - CyQ've CQ8060A CDRW drive - Planex eXtreme Drive RX-25HU USB-IDE cable (not model RX-25U) config USB_STORAGE_DPCM bool "Microtech/ZiO! CompactFlash/SmartMedia support" depends on USB_STORAGE help Say Y here to support the Microtech/ZiO! CompactFlash reader. There is a web page at . config USB_STORAGE_HP8200e bool "HP CD-Writer 82xx support (EXPERIMENTAL)" depends on USB_STORAGE && EXPERIMENTAL help Say Y here to include additional code to support Hewlett-Packard 8200e/8210e/8230e CD-Writer Plus drives. config USB_STORAGE_SDDR09 bool "SanDisk SDDR-09 (and other SmartMedia) support (EXPERIMENTAL)" depends on USB_STORAGE && EXPERIMENTAL help Say Y here to include additional code to support the Sandisk SDDR-09 SmartMedia reader in the USB Mass Storage driver. Also works for the Microtech Zio! SmartMedia reader. 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. config USB_STORAGE_JUMPSHOT bool "Lexar Jumpshot Compact Flash Reader (EXPERIMENTAL)" depends on USB_STORAGE && EXPERIMENTAL help Say Y here to include additional code to support the Lexar Jumpshot USB CompactFlash reader.
