You might trust them but I only go to source for drivers. I don't like the driver download sites as I don't believe them all the time. They would be my final choice**

its possible Microsoft have drivers for it already. I would buy card and see if windows identifies it without needing drivers
hard to say what these are: https://www.catalog.update.microsoft.com/Search.aspx?q=asmedia

**wait, no, my final last ditch try would be a 3rd party driver updating software but they are just as bad as the websites and might use them as a source.
I hope that the new card will work with Windows 10's inbox drivers.

Time will tell ☺
 
Having not read the whole thread, came across something the other day. A system at work in windows 11 wanted some memory integrity setting enabled for security. When I did so, a pretty common Logitech camera wouldn’t work. Disabled the setting and it was happy again.

I can't speak for users with the same problem on Win11, but on Win10 I believe that it's a driver issue.

I have three PCI-E to USB 3.0 cards (two with Renesas chip, one with Via chip), they all worked fine from WinXP to Win10 20H. The problem only appears with the latest 21H2 update.

After tinkering with the cards for a couple of weeks, I tracked the issues down to :

1. Power issue : the cards are disconnected automatically after a certain mount of time (usually 10 to 15min, sometimes shorter), there is no setting in Win10 that can fix it because the driver is corrupted. The only way I can temporarily fix it is to connect an USB fan to one of the USB 3.0 port to keep the card powered, so far I managed to keep the cards "live" for a couple of hours.

2. I/O issue : while I can keep the cards somewhat "working", I can copy files from a HDD to another HDD back and forth. But if the transfer reached a certain speed the cards are disconnected again.

Playing a movie file from one of the HDD will also disconnect the cards, no matter what player is used (Windows Player, VLC...)

All the issues mentioned above apply for both SATA HDD and USB Flash.
 
If I removed all the drivers that have been installed manually, Windows would detect and install its own drivers for the card, but the problem remains, the card will disappear shortly and the USB 3.0 Root Hub driver crashes, leaving the Host controller with the yellow mark.

 
Ok so I got the card with ASM chip delivered today, but unfortunately it didn't work. Same errors, same behaviors like my other cards with Via and Renesas chips.

Just letting you know so that you won't waste your time and money on a problem that is not yours.



 
So this is the list of my

pcie to USB 3.0 cards that stopped working on Windows 10 after the 21H2 update. They use chips from Via, Renesas and Asmedia.

If you are using one of those cards and it's actually working fine, think twice before updating your Windows 10 unless you know for sure that the card will work with it.

If it doesn't work on Renesas, VIA and ASMedia cards, then it's probably not their USB chip drivers at all. It's more likely something 21H2 did to the drivers for ICH7 Southbridge or its PCIe 1.0a. This may be why nobody else has chimed in to report the same problem. BTW the ASMedia datasheet says it's intended for PCIe 2.0, so Nehalem's PCH not any ICH.

My working cards show up as Renesas xHCI 0.96 (Microsoft) and I have them plugged into PCIe 1.1 slots. FWIW, the cards are Vantec UGT-PC312 and Startech PEXUSB3S2, but given the above you may actually have to drop down to 32-bit PCI to get a working card.

At 133MB/s you are not going to see 6gbit SATA 3.0 600MB/s speeds, but ICH7 generally was not used with chipsets that support multiple Northbridge-attached slots at x8, and I'm not sure the single 1.1 x16 slot would work for anything but a GPU even if you were willing to use the IGP or go headless.

There is another option in a PCIe to SATA-600 adapter card. Now at x1 PCIe 1.0a it's going to be limited to 250MB/s in each direction, but then so were your USB 3.0 cards so it's not like you had real SATA-600 with those anyway. Even when using only one USB port at a time, the card's interface limits things to half the theoretical bandwidth of USB 3.0.

Even x1 PCIe 2.0 cannot feed one SATA-600 and would only allow one USB 3.0 port to operate at full speed at a time. Such cards really need a x4 connection

I have taken it into account.

That's why I have multiple USB 3.0 cards, for example I could use a HDD on the Renesas card and other HDD on the Via card so they always operate at max speed (as far as the hardware allows).

But now none of the cards works :(

Wait, so the x16 slot worked with the same USB cards before and doesn't anymore? There goes my theory as that's PCIe 1.1 and not on the ICH at all.

It'd probably be a waste to try a PD720200 USB card in there when you could see if a single many-SATA-port x4 or x8 card would better solve your port shortage without going through USB.

Yes the cards used to work on any pci-e slot (my motherboard has three, 2 x1 and 1 x16).

I'm already out of idea, I think I will stick with USB 2.0 while waiting for a possible drivers update from MS.

That being said, the last windows update does more harm than good. I've seen a lot of issues with those chips online, some having problem with USB, others have problem with WiFi/Bluetooth cards...
 
A couple of days ago my computer received an update from MS called :

2022-09 Cumulative Update Preview for Windows 10 Version 21H2

After the update I tried all the cards one by one, but none of them works.
