Hi,

 

So from reading thru this thread, the Sonnet card is the best and only working choice for whose who want to run a multi controller usb card with unraid seamlessly. It would be nice if someone created a database for these things, save some people some money lol

I'd suggest you forward that sentiment on to Lime Tech themselves. :D

A note on the StarTech PEXUSB3S44V.  I recently picked up two on eBay and they turned out to be different hardware revisions.  One works great with passthrough and the other does not.  Unfortunately it's the newer (and more readily available) version that has problem.  I have (3) Windows 10 guests under ESXi 6.0.  Each guest gets an old Radeon 240 and a single USB3 controller from the PEXUSB3S44V.

PI40202-6X2B -> Recognized by Windows 10 guest, works great

PI40202-7X2B -> Recognized by Windows 10 guest, throws code 10

 

I confirmed the 6X2B card worked then shut the host down and swapped the 7X2B into the same PCIe slot.  I made sure both cards had the same PCI ID's, firmware revision, etc.  The 7X2B caused the guests to throw code 10.  Shut it down, swapped the 6X2B back in and everything worked fine again.

I have one of the sonnet cards with 4 controllers.  My x399 build has all slots filled so I got an adapter for U.2 to pcie x4 thinking that I would be able to see the card with no issues, but of course am having issues.  Not sure if there is a bios option I am missing, or the adapter just doesn't work as intended.  I can verify that the card gets power and will light up a device when powered on, but not detecting the card.  Has anyone tried that, or have any ideas?  I have an Asrock Taichi x399 board and 1920x running in it.

Well it looks like a bios change to disable C6 in zenstates was the answer.  I did that, and low and behold- 4 fresno logic USB controllers were visible.  I did the vfio edit for that device and now I have all 4 controllers passed through to each gaming station.  I'm picking up a few 4 port hubs from best buy on the way home and should have plug and play glory available to my crew tonight!!! YAY fallout 76 weekend for us!  So nice not to have to map usb devices for them individually any more.  Especially since one of my crew insists on using controllers- and likes the steam for some games and xbox for others.  Also spun up a windows host for game servers- since ubuntu was more difficult to manage and wine is unhappy with some windows apps.  Have Ark(both windows and steam), 7days2die, conan exiles, the forest, empyrion, and L4d2 spun up on that host and having no issues with all 4 connected locally- with 8 players from the internet- on most of those sessions where possible.

coming back here to rez an old thread.  unfortunately the allegro pro is no longer being produced and i cant find it anywhere on ebay.  has there been another method to getting USB's passed through correctly?  or are there just no options for something like this?

Another Startech "sucker" here. Wrote this yesterday on another topic:

Same here - Unraid 6.8.0-rc5, my Windows VM Error:

 

"

This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.

"

 

I think it is related to the PCI Bridge that came with the PCIe:

I tried:

- Enable ACS Override Downstream

- Enable ACS Override Multi-Function

- Both

- Blacklisted the device to Unraid's kernel (vfio-pci.ids=xxxx:yyyy)

 

If I boot my Windows without Unraid the card works.

Something interesting about the Sonnet card: it uses a PCIe switch chip to split a PCIe_V2 x4 connection into two x2's each going to one of two USB controller chips. Apparently, each of those USB chips has two "sub-devices" each of which can be passed (as desired here).

 

Compare that to the Startech card, which also has a PCIe switch chip (from the same company), but its switch splits a PCIe_V2 x4 connection into four x1's, each going to its own USB chip. Yet, this one causes grief.

 

In addition to working as you all desire, the Sonnet card has the advantage of higher maximum single-port throughput, since its (2) x2 chips can share their two-lane bandwidth on-demand/as-needed to its two "sub-devices". Whereas, the Startech, even if it worked for you, would limit each "sub-device" to an x1 lane of throughput. [I realize that connectivity (vs bandwidth) is more the goal here, but ... just saying ...]

I assumed that since the pro 3.1 card is not the same as the 3.0 card, that there would be its own problems.  but it sounds like this has been documented and tested as working with unraid. 

 

Still, if i have learned one thing from this forum is things arent always as they appear.  have you confirmed that the 3.1 pro card works with unraid? Often people just refer to the "Pro" card and there are 2 different cards we are talking about here. 

 

Thanks,

[my mistake] Yes, all those "generic" references to the Sonnet Allegro Pro card clouded my thinking. [Note: the one hyper-link to the Pro card (on first page) now 404's--shame on Sonnet--they should have "preserved" the link, redirecting it to its new "home", under their LegacyProducts, and suggested the new "Pro".]

 

I totally agree with you regarding the need for documented specificity before taking action on a reference/suggestion for a functioning solution. And, NO, I'm not using any of these cards--just a passing interest in atypical "solutions". [I was aware of this thread, but never actually dug into it--then I was trying to find out more about the Pericom Semiconductor PI7C9X2G608GP switch for this UnRAID thread

... and here we are.

 

I don't know what chips are used on the Allegro Pro 3.0 card, but the 3.1 card uses the Pericom PI7C9x2G308GP (can see it in the picture @ the Amzn lnk)  [4<==>2x2]. I'm real curious to know which chip is used for the (2) USB controller chips. If anyone does get one to try, please do post a relevant snippet from either the kernel meggages or from lspci. tnx

[Edit] Just found it--the 3.1 Pro uses 2 Asmedia ASM1142

 

Sorry for the confusion/distraction. Good luck to all on your quest.

So I just purchased the 3.1 card, the new one they still sell, thinking it was the card with 4 usb controllers onboard because I did not read this thread carefully enough. Bummer for me, only 2 controllers on the new card. I'm considering returning it and ordering the 4 controller version, found it for sale in a few places. Unfortunately, I'm not even able to get the new 3.1 show up as an "other PCI Device" for my VMs. It seems to be showing the Pericom PCI bridges in System Devices, but no USB controllers. I tried with the PCIe ACS Override setting enabled, but no dice. Anyone have any ideas about how to troubleshoot? Has anyone had any luck even using the new card? 

 

For anyone looking into this in the future, the card with 4 controllers has a purple PCB, and the model name is: USB3-PRO-4PM-E. Unfortunately, it is no longer in production. 

The new USB 3.1 card, with only 2 controllers, that I cant get working, has a black PCB and is model name: USB3-PRO-4P10-E.

I can tell you something.

 

This does not work with Unraid (neither in the host OS, neither in the VMs) - It only works here in a physical Windows installation:

StarTech.com 4 Port USB 3.0 PCIe Card w/ 4 Dedicated 5Gbps Channels (USB 3.1 Gen 1) - UASP - SATA / LP4 Power - PCI Express Adapter Card (PEXUSB3S44V)

These are my candidates to "it might work" based on previous posts around here and other forums:

Too bad I live in Brazil and the cost to ship here is prohibitive due to taxes (100% taxes on the card + shipping: ridiculous).

@agarkauskas The Sonnet one you mentioned is what I purchased, the USB3-Pro-4P10-E. I am unable to get it functioning in Unraid. Also, even if I could, it only has 2 controllers onboard, whereas the old one had 4 (meaning you could pass through each individual port to a different VM, which, with Hubs, means you have lots of hot-pluggable USB devices to 4 VMs at once). The old one was pretty cool. 

 

It seems, however, that they may have just started manufacturing it again? I had ordered one from a thirdparty seller on Amazon for a bit over $100, logged on today to check the status of the order (shipping was going to take forever because of the pandemic) and, lo and behold, Sonnet Technologies on Amazon was selling them for $49.99. After a quick wtf on my part, I went to Sonnet's website, and, sure enough, they have it listed for sale. I swear, just 2 days ago I was looking for this part on their site and they had a listing saying it had been discontinued. I'm not really sure what is going on here, but it seems like they may have started reproducing this part. Maybe an updated version, I'm not sure, but far as I can tell the images look the same. They still have the purple PCB with 4 controller chips visible. I ordered 2 on Amazon, and I'm hoping for the best! I'll update in this thread when I find out if its for real or not.

@swallace, thanks a lot! Hope you succeed with Sonet. Please let us know your findings!

Not sure when I will be able to get back to USA in this Corona-Mess to buy a decent USB controller for my VMs under Unraid.

One thing I will try in the near future is ProxMox. If it could support my StarTech on the host OS I might be able to use it in my VMs. I will let you know my findings.

I do hope you are correct, but a few indicators suggest that the card you linked to is not the ‘old’ 4x discrete controller card:

https://www.sonnettech.com/product/legacyproducts/allegroprousb3pcie.html

 

The old one is a usb3-pro-4pm-e, the linked card is usb3-4pm-e (no ‘pro’)

The old one is 4x pcie, this is 1x pcie

The old one has 4x controller chips ranged vertically beside the rear-facing ports, not visible on the usb3-4pm-e

The old card retailed for well north of $100. At half that, the linked card would be a star bargain

 

I look forward to your findings though, and live in hope......

@meep Thanks for chiming in, I'm afraid you're right. I'll wait and see, but I'm afraid your're correct. Guess we'll see. I'll update when it comes in. 

 

Also, great blog post. I think I've just learned that I'm going to end up paying way too much money for a rack-mount PCI Expansion Chassis. All for some USB ports, lol.

Judging by the look that is going to be a card with four Renesas uPD720202 chips behind ASMedia 1806. Many different brands, but same looks of the card. When i you test it please do tell if it's worth buying.

Just wanted to comment and report back.

 

The card that @agarkauskas posted works very well.

 

Here's a picture of the card:

Here's the relevant lspci -nn of the card:

08:00.0 PCI bridge [0604]: ASMedia Technology Inc. Device [1b21:1806] (rev 01)

0c:00.0 USB controller [0c03]: Renesas Technology Corp. uPD720202 USB 3.0 Host Controller [1912:0015] (rev 02)
0d:00.0 USB controller [0c03]: Renesas Technology Corp. uPD720202 USB 3.0 Host Controller [1912:0015] (rev 02)

 

The interesting thing about the card is that the usb headers on the front of the cards are also mapped to the ports at the back. Each header offers an additional 2 USB3 ports. The header at the top maps to the top two ports at the back. Each header port is also mapped to their own respective controller. So a single controller has 2 USB3 ports as long as you're using the headers. Otherwise you just have the 1 port at the back.

 

I do have to mention that the way this card is designed, the ports have pretty much no clearance and can be hard to insert. I had a tough time with the port that is closest to the bottom of the card when inserted. I had to insert the usb plug through the pci-e slot at the back first and plug it into usb socket on the card. Keep it plugged in while you insert the card into the pci-e slot on the motherboard. The rest of the ports seem to be fine.

 

I have a StarTech PEXUSB3S44V PI40202-7X2B and that throws Error Code 10 as seen above.

 

I have a StarTech PEXUSB3S44V PI40202-6X2B that's on the way and I'm pretty interested to see if it actually works and find out what PCI bridge is running on this revision of the card. I'll post back with a lspci -nn when the card arrives and test if it actually works.

 

Personally even if the older revision StarTech card works, I'm more inclined to keep the one purchased from AliExpress due to the expansion options it offers.

Unfortunately I didn't get a lspci -nn of the 7X2B variant but based on this topic I believe it's a Pericom PCI brige as compared to the 6X2B which uses a PLX Technology bridge. I can confirm that the card is able to be pass(-ed)through to Windows and works well (so far).

 

I have another 2 cards on the way as I am doing VFIO with MacOS but I think the Renesas uPD720202 chipset doesn't play well with MacOS. It works but isn't able to carry streaming data. There was some talk about this somewhere but can't exactly remember where. I'll post a link if I find it in the future. 

 

The two new cards that are coming are of the following models: 

U3X4-PCiE4XE111 (http://www.ioi.com.tw/products/proddetail.aspx?CatID=106&DeviceID=3035&HostID=2035&ProdID=1060179)

U3X4-PCIE4XE113-Ax (http://www.ioi.com.tw/products/proddetail.aspx?CatID=106&DeviceID=3035&HostID=2035&ProdID=1060181)

 

They both have Fresco Logic 1100 chipsets and they've been reported to work natively on MacOS. Both of the above cards are quad channel cards with the latter being a low profile variant which has a usb header on them. The neat things about these cards is that you won't have to be frustrated trying to plug/fit the USB port in the socket.

 

The U3X4-PCiE4XE111 seems to be the same as the old Sonnet Allegro Pro variant that's no longer being sold so I'll do the necessary and report back when I get them.
