USB Issues on Haswell based Xeon

Hi everyone, I built a hackintosh on a Dell 5810 with 64gb of ram and a xeon 2660. I did this through Proxmox, and I got the install done correctly for the most part, GPU (rx570) working on metal, dedicated SSD for it, etc. The only issue I am really struggling with now is the USB. I initially tried with passing USB ports through and they work to a point, but really struggling with hot plugging, speed and weird stability issues, and the limit in the GUI as well. I decided to Passthrough all three USB controllers which is a c610/x99 series and it doesn't really work either. The keyboard/mouse work at the boot menu just fine but as soon as Sonoma gets to the login screen it moves like molasses, very laggy, almost unfunctional. What I have tried to resolve this thus far:

  • use the USBMap tool to map the ports, however it does not see the usb 3 ports at all.
  • The USB 2 ports are detected, but are dog slow after setting it to USB 2 and mostly unresponsive.
  • Tried the USBX and legacy USB kext with no difference.

Note:

  • All Controllers and devices are in their own IOMMU group
  • Blacklisted the controllers proxmox vfio
  • Disabled the controller completely in proxmox

I have another Haswell based system with different USB controller from Intel that I have working in this method, but on this chipset it just seems broken. Is there anything else to try or kext somewhere for it? I am thinking of just buying a dedicated PCI controller at this point, any recommendations for Sonoma?
