MOTU USB MIDI drivers have been developed and tested for full compatibility within Windows 98SE, ME, 2000 and XP. You may have to make a few changes to the BIOS settings of your computer. If you are unfamiliar with the BIOS of your copmputer, you should contact the manufacturer of your motherboard or consult the user manual for your motherboard.

If your BIOS is set to its default setting, make sure that USB plug and play and USB legacy support settings are enabled. These settings are often disabled as default settings for most current generation BIOS. Also, for a fail-safe installation, make sure you have all the latest updates for your BIOS and chipset. The Windows operating system installer CD used with your system may not have the most up-to-date drivers for your USB port. A chipset and/or a BIOS update will ensure this. For example, if your computer is equipped with USB 2.0 ports, make sure you have the most current chipset drivers to allow for USB 1.1 legacy compatibility, which is what is required for all MOTU USB interfaces.

Notes to tech: Also make sure you have the latest USB ROM installed in your MIDI interface. You can do so by locating the sticker on the bottom of the unit, it should have a "M/W" located next to the serial number. (This does not not apply if you are using the Micro Lite, Express 128, Express XT w/ removable rack ears, and Micro Express w/ removable rack ears).

A note for Windows 2000 users Windows 2000 imposes a 10 port limitation with MIDI. For example, if you have 2 Express XT's connected to your Windows 2000 computer, only 10 out of the 16 ports will publish within the operating system and your MIDI software. This limitation is not present within Windows XP.
