UMASS(4) FreeBSD Kernel Interfaces Manual UMASS(4) NAME umass -- USB Mass Storage Devices driver SYNOPSIS device umass DESCRIPTION The umass driver provides support for Mass Storage devices that attach to the USB port. Supported are: IBM 256MB USB Drive(MSYSTEM DiskOnKey2) Iomega USB Zip 100 drive Iomega USB Zip 250 drive Logitec LDR-H443U2 DVD-RAM/-R/+R/-RW/+RW Drive Microtech International, Inc. USB-SCSI-HD 50 USB to SCSI cable Panasonic ("Matshita FDD CF-VFDU03") Panasonic KXL-CB20AN Portable DVD-ROM/CD-R/RW Panasonic KXL-CB35AN(DVD-ROM & CD-R/RW) Trek Thumbdrive 8MB VAIO floppy drive (includes Y-E Data Flashbuster-U) The driver also supports some USB adapters for removable media. Among the supported models are: PNY Attache Flash Drive SanDisk SDDR-31 (Compact Flash) SanDisk SDDR-75 (only Compact Flash port works) Sitecom CN-300 MultiFlash (MMC/SD, SmartMedia, CF, MemoryStick) Among the supported digital cameras are: Asahi Optical (PENTAX) Optio 230 & 330 usb(4) and one of uhci(4) or ohci(4) must be configured in the kernel as well. Last but not least, support for SCSI drives, da(4). EXAMPLES device umass device scbus device da device pass Add the umass driver to the kernel. camcontrol rescan 0 Rescan a Zip drive that was added after boot. The command above assumes that the Zip drive is on the first SCSI bus in the system. camcontrol rescan 0:0:0 camcontrol rescan 0:0:1 camcontrol rescan 0:0:2 camcontrol rescan 0:0:3 Rescan all slots on a multi-slot flash reader, where the slots map to separate LUNs on a single SCSI ID. Typically only the first slot will be enabled at boot time. Again, this assumes that the flash reader is the first SCSI bus in the system. bsdlabel -w da0 zip100 newfs da0c mount -t ufs /dev/da0c /mnt Write a disklabel to the Zip drive (see vpo(4) for the disktab(5) entry), creates the file system and mounts the new file system on /mnt. newfs_msdos /dev/da0 Create a new FAT type file system. Care should be taken not to run newfs(8) on devices that already contain data, as this will result in the information being lost. Many consumer devices such as digital cameras automatically create MS-DOS based file systems when storing information such as images and videos. These file systems can be accessed by specifying the file system type as msdos when using mount(8).
