Using USB Diskette Devices

USB diskette devices appear as removable media devices. USB diskette devices are not managed by the fd (floppy) driver. Applications that issue ioctl(2) calls intended for the fd (native floppy) driver will fail. Applications that issue only read(2) and write(2) calls will succeed. Other applications, such as SunPCI and rmformat, also succeed.

The USB diskette device is identified as a SCSI removable media device. The device is available for access under the /rmdisk directory.
