Reddit mentions of High Point 4-Port USB 3.0 PCI-Express 2.0 x 4 HBA RocketU 1144D

A HighPoint 4-Port USB 3.0 PCI-Express 2.0 x 4 HBA RocketU 1144D.

It works, but I do have to use the pcie_acs_override kernel command line option (+ patch) to split the individual controllers into separate IOMMU groups for PCI-e passthrough. Works for me without issue, but ymmv -- in general, overriding PCI-e ACS isn't recommended.

I also tried a StarTech 4 Port PCI Express (PCIe) SuperSpeed USB 3.0 Card Adapter w/ 4 Dedicated 5Gbps Channels - UASP - SATA / LP4 Power but had issues. I can't remember what exactly, but I couldn't get it to work as individual controllers.

Maybe with this card. I do NOT have experience with it myself but /u/RulerOf has, as mentioned here.

Glad that worked for you.

> Plus I don't have to pass through specific USB devices, so if I want to change out the keyboard or mouse or connect something else (USB flash drive) I can do that without rebooting or modifying the vm configuration!

I find this type of setup to be most convenient myself due to this behavior. It's annoying to have to "intercept" USB devices at the host and re-route them to the guest, when you can easily dedicate individual ports for that purpose.

My best and only suggestion would be the Highpoint RocketU 1144D. Each port on the card is a separate PCIe device, allowing for PCI-based USB connectivity for up to four different VMs simultaneously. It's also well-known among early adopters of VFIO setups to be insanely compatible. I theorize that it's a combination of the PCIe switches they use, and the fact that it's fully bus-powered, allowing this card to respond favorably to software resets performed by the host.

This one? https://www.amazon.com/HighPoint-4-Port-PCI-Express-RocketU-1144D/dp/B015CQ8DCS

Then why do they recommend this cheaper USB cards in their official blog post as well?

$24 vs $109 is quiet a big difference and I feel like there shouldn't really be a need to buy another extra hardware besides the extra camera (and possibly extension cables) to get roomscale. This is making me furious!

i'd use https://panthema.net/2013/disk-filltest/ to test the integrity of the drive and subsystem. you should get progressively slower speeds as the drive fills but not a sudden drop. if it fails to complete the fill something is wrong with either your drive, drive's usb controller, cable, usb 3.0 subsystem or driver/software/configuration...

some usb3 controllers are also pure shit. had a few nec 2 port controllers that were garbage and caused nothing but problems, have since upgraded to a few of these https://www.amazon.com/gp/product/B015CQ8DCS/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1 and have had zero problems/drops/etc

also if your internal drive is fragmented to hell it will slow the transfer

No this card is for rift S. This card is not sufficient for CV1.

For CV1 you would want to use this:
High Point 4-Port USB 3.0 PCI-Express 2.0 x 4 HBA RocketU 1144D https://www.amazon.com/dp/B015CQ8DCS/ref=cm_sw_r_cp_apa_i_pcFqDbHC7MZ95

The High Point has 4 usb controllers in 1 card, good for cv1,.and does not require power (instead uses pci-e x4 slot). So you could do 3 sensors and the Rift cv1 HMD for instance all off this one card, no power lead needed

Thanks for the recommendation, looks like some people have had issues with it through and that lead me to one which multiple sources recommended AND that has 4, not 2, independent ports. Thank you!

There are better cards available, but they come with a price.

I've had bad luck with passing through USB controllers. Someone else here mentioned the HighPoint PCIe card to me a long time ago. It has 4 ports and each has its own controller than can be assigned to a VM. I picked one up on their suggestion and it works flawlessly for me. The model is: http://www.amazon.com/HighPoint-4-Port-PCI-Express-RocketU-1144D/dp/B015CQ8DCS/ref=dp_ob_title_ce

I don't have a Lenovo TS140 though. I'm using a Supermicro X9SRL-F.
