To ensure smooth operation, consider the following:
1. Pay attention to the USB data rate
USB 2.0/3.0 interfaces require their own USB 2.0 controller due to high data rates.
Even if your computer has multiple ports, avoid using other USB 2.0 devices (e.g., external hard drives) in parallel if only an extended USB host is displayed in the Device Manager.
If USB 1.1 devices (e.g., Codemeter dongles) are connected, ensure the bus is not slowed down.
Tip: Installing a second USB 2.0 controller (PCI or PCMCIA card) dedicated to the audio interface often solves many connection issues.
2. Use high-quality cables
Cheap USB extensions can cause connection failures, while a good-quality, longer cable usually resolves such problems.
3. Ensure audio inputs are assigned correctly
Use balanced audio inputs if your mixer or sound source supports them.
Invest in proper cables for reliable connections.
Avoid using a USB 3.0 interface with older devices to prevent compatibility problems.
