Based on the proven HighPoint RU1444C USB-C Host Adapter controller, Catalyst PXIe-USB delivers reliable, high-bandwidth USB-C connectivity over a PCIe Gen 3 ×4 host interface. The RU1444C provides native USB 3.2 Gen 2×2 support with hardware-level port isolation, ensuring that a fault or bandwidth saturation on one port does not affect the others. USB-C devices connect and enumerate as if plugged directly into a host PC — fully compatible with existing application software and instrument drivers. No custom RADX drivers are required.
