You weren't dreaming. One example: Amazon.com: Kanguru SS3 USB 3.0 16GB Flash Drive with Physical Write Protect switch: Computers & Accessories

I wasn't aware of the existence of usb flash drives with this feature. Reminds me of a time when floppies ruled the world.

UMASS(4)						   BSD Kernel Interfaces Manual 						  UMASS(4)

NAME
umass -- USB Mass Storage Devices driver SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file: device scbus device usb device umass Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): umass_load="YES" DESCRIPTION
The umass driver provides support for Mass Storage devices that attach to the USB port. To use the umass driver, usb(4) and one of uhci(4) or ohci(4) must be configured in the kernel. Additionally, since umass uses the SCSI sub- system and sometimes acts as a SCSI device, it requires da(4) and scbus(4) to be included in the kernel. HARDWARE
The umass driver supports USB Mass Storage devices, including: o ADTEC Stick Drive AD-UST32M, 64M, 128M, 256M o Denno FireWire/USB2 Removable 2.5-inch HDD Case MIFU-25CB20 o FujiFilm Zip USB Drive ZDR100 USB A o GREEN HOUSE USB Flash Memory "PicoDrive" GH-UFD32M, 64M, 128M o Huawei Mobile (SD slot) o IBM 32MB USB Memory Key (P/N 22P5296) o IBM 256MB USB Drive (MSYSTEM DiskOnKey2) o IBM ThinkPad USB Portable CD-ROM Drive (P/N 33L5151) o I-O DATA USB CD/CD-R/CD-RW/DVD-R/DVD-RW/DVD-RAM/DVD-ROM Drive DVR-iUH2 (CDROM, DVD-RAM only) o I-O DATA USB x6 CD-RW Drive CDRW-i64/USB (CDROM only) o I-O DATA USB/IEEE1394 Portable HD Drive HDP-i30P/CI, HDP-i40P/CI o Iomega USB Zip 100/250 drive o Iomega Zip750 USB2.0 drive o Keian USB1.1/2.0 3.5-inch HDD Case KU350A o Kurouto Shikou USB 2.5-inch HDD Case GAWAP2.5PS-USB2.0 o LaCie P3 HardDrive USB 200GB o Logitec LDR-H443U2 DVD-RAM/-R/+R/-RW/+RW drive o Logitec Mobile USB Memory LMC-256UD o Logitec USB1.1/2.0 HDD Unit SHD-E60U2 o Logitec USB Double-Speed Floppy Drive LFD-31U2 o Logitec USB/IEEE1394 DVD-RAM/R/RW Unit LDR-N21FU2 (CDROM only) o MELCO USB Flash Disk "ClipDrive", RUF-C32M, -C64M, -C128M, -C256M, -C512M o MELCO USB Flash Disk "PetitDrive", RUF-32M, -64M, -128M, -256Mm o MELCO USB2.0 Flash Disk "PetitDrive2", RUF-256M/U2, -512M/U2 o MELCO USB2.0 MO Drive MO-CH640U2 o Matshita CF-VFDU03 floppy drive o Merlin SM300 MP3/WMA Player (256Mb) o Microtech International, Inc.

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). SEE ALSO
