13.2 Configuration
Legacy USB support can be enabled or disabled in the T-MOPSlcdSA BIOS Setup Utility. For
detected mass storage devices there are several configuration options.
Refer to the “USB Configuration Submenu” and the “Boot Menu” section in the “Appendix B: BIOS
Operation” chapter for information on configuration.
13.3 Limitations
In order to guaranty correct detection of plugged devices and to avoid electrical problems which
may lead to unreliable data, you have to ensure that no cables exceeding 1 meter cable length are
used to connect the USB devices.
Some USB floppy disk drives and sticks make trouble by formatting. The following floppy devices
are known to fail:
 Mitsumi D353GUE
 Sony MPF88E–U1
 Y-E USB-FDU
If you have problems to boot from an USB stick, set its “emulation type” in the BIOS setup to Hard
Disk. See the chapter “USB Mass Storage Device Configuration Submenu” for details.
An USB-Mouse will not work under DOS even if USB legacy support is enabled.
