Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
umass_load="YES"
To use the umass driver, usb(4) and one of uhci(4) or ohci(4) or ehci(4) or xhci(4) must be configured in the kernel. Additionally, since umass uses the SCSI subsystem and sometimes acts as a SCSI device, it requires da(4) and scbus(4) to be included in the kernel.
device umass device scbus device da device pass
Add the umass driver to the kernel.

| “ | "I liken starting one's computing career with Unix, say as an undergraduate, to being born in East Africa. It is intolerably hot, your body is covered with lice and flies, you are malnourished and you suffer from numerous curable diseases.

They already think that the writing of shell scripts is a natural act." | ” |
