I’m not sure my computer has a compatible USB chip on it. How do I find out which chip it has, and which are compatible with the UA-1D, UA-1A, UA-20, etc?

The built-in USB ports on any Apple G3 or G4 (300 mHz or faster) are compatible; provided the Mac running OS9.0.4 or higher.

Below is a listing of the currently compatible USB chips for PC/Windows (As of 2/28/03). For up to date listings, check

* Intel 82371AB PCI to USB Universal Host Controller

3. Double-Click the Universal Serial Bus Controller icon in the Device Manager list.

If you do not have a compatible USB Host Controller, there is an option other than replacing your mother board. We carry the ADS Turbo Quad 4 PCI card that offers 4 full bandwidth USB ports that are known to be compatible with USB audio. Our price on this card is $49 plus shipping and handling.

The USB Turbo Quad 4 offers a powerful performance advantage over all other USB host controllers by providing full USB bandwidth for each port rather than sharing USB bandwidth over all ports. This results in an increase in the number of devices that can simultaneously operate. Only the USB Turbo Quad 4 ensures High-Bandwidth simultaneous operation of USB devices such as cameras, speakers, scanners, modems, USB audio devices, and other bandwidth intensive peripherals.
