The HP Z4G4 workstation I have, came without the USB type C connector, which is capable of SS+ enumeration and data transfer rates (USB 3.1 gen2).
I have a requirement to enumerate a SS+ device. Is the best option to use a PCIE to USB 3.1 gen2 expansion card? If yes, which is the ideal model for Z4G4 workstation? Also want to ensure that form factor is correct.

you have to use a add in card to get usb 3.2.gen 2 capability
while there are many off brand usb 3.2 cards that say they support gen 2 data rates it's hit or miss in regards to card build quality and driver support
most of the name brand usb 3.1 gen 2 cards use the asmedia usb chip and one that i have personally tested is the
silverstone SST-ECU04-E pci-e 2.0 USB 3.1 Gen 2 card (10 Mbps) which has a19 pin front panel connector and supports 2 usb 3.1 ports using type a usb (not usb c) at 10MBps which is usb gen 2 speed
a similar model that uses the same chip, and does use usb c style connector is the ECU02-E card,... however this card will only give it's rated throughput if used in a PCI-E 3.0 system

Thank you for the reply.
so is the speed you are achieving 10Mbps only? I was looking for speeds of 10Gbps in my case.
Also, you mentioned PCIe gen2. PCIe gen2 only supports upto 5gbps I believe. Correct me if I am wrong. So in that case, I should be looking for a PCIe gen3 card for the USB 3.1gen2, to achieve 10Gbps on one port?
