The PCI specification permits a single system to host up to 256 buses, but because 256 buses are not sufficient for many large systems, Linux now supports PCI domains. Each PCI domain can host up to 256 buses. Key Workflow: The PCIe LX-DANTE sound card bridges professional audio software applications to Dante networks. By supporting 128 x 128 redundant channels, and providing extremely low latency, LX-DANTE matches all the requirements for high channel density, low latency, and reliability of professional DAWs used for high quality recordings, processing, and multi-channel playout over Dante networks.
Could someone point me to a USB 3.0 PCI (not PCI-E) card that works with Ubuntu 16.04 and is cheap?
The only ones I've found are 40-50 pounds and the compatibility is unknown.

- This question does not appear to be about Ubuntu within the scope defined in the help center.

There is barely a market for PCI USB 3.0 cards, probably that's why prices are high. PCI as commonly distributed in the 32-bit at 33 MHz version only supports transmission of 133MB/s, which means pretty much 1000Mbit/s. Subtracting some overhead for the protocol, this already gets pretty close to the maximum speed of 430Mbit/s of USB 2.0. USB 3.0 would allow up to 5Gbit/s, far beyond PCI's capabilities. Don't expect any major improvement in transmission speed comparable to PCIe cards! Even a single USB 3.0 port will be able to occupy the link, which is of course shared among all USB ports on the card.
A quick survey on PCI USB 3.0 cards reveals most of them is running the VIA VL80x chipsets, which is told to be supported by Linux since quite some years. As this is a PCIe chipset, there might be some issues because of PCI-PCIe bridge chips, but those are likely also supported well.
