3rd-party Usb pcie card or usb hub

[Lutzpime]

Hi.

I bought an ts 453d to replace my 453Be. But the new one has significantly less USB 3 ports. Are there any 3rd party usb 3 pcie card (5Gbps would be enough) that is compatible (the original is quite expensive) or are there any compatible active USB hubs (I read that since the tr enclosures came out, that hubs are problematic)?

Thank you for your support!
