Test USB 3.0 Cards (A ADWITS, Inateck, and Syba) about raspberry-pi-pcie-devices HOT 10 OPEN

I think I made the comment elsewhere, but anyway.
With the USB3 VL805 card I have (Tamkyo - https://www.amazon.co.uk/gp/product/B08HLKCLX4/), if the plug was pushed in too slowly then it negotiated at 480Mbit/s presumably as the high speed USB3 pairs hadn't connected, however it didn't then renegotiate when pushed fully in. I don't see this as a big failing as it is more down to the connector (and probably protocol), but it is worth bearing in mind.

DisplayPort Alternate Mode on USB-C requires a GPU that supports a DisplayPort connection first.

@6by9 - Woah; that's an interesting find! I'll have to do a little more testing, and see if it's the case with these cards. Luckily they don't require a recompile of the kernel to use, so it's quicker to test with them :D

So this Syba SD-PEX20199 PCIe x1 USB 3.1 & 3.0 adapter

Does it support display on the USB type c or only file transfer

I got my CM4Lite Wireless 4GB today and my card (VL805-USB3.0-VER1.0) works. It is not the 'A ADWITS' one and everything I have tested mounts at USB3 speeds if it is plugged in quickly enough.

Hi,
I did some design change in CMIO board and used VL805 instead of PCIe slot (similar to Raspberry Pi4) but it is not working. The circuit is almost similar to the PCIe cards available in the market, I used Rasp-Pi4 and logilink card for reference (https://www.reichelt.de/de/de/usb-controller-3-0-4-port-pci-express-karte-logilink-pc0057-p112409.html?trstct=pos_2&nbc=1&&r=1 ).
The only difference in this card and my design is the flash memory. I haven't used flash IC in my design because it wasn't used in the initial version of Raspberry Pi4. But when I checked logilink card circuitry, I found that flash memory has been used in it and it works properly with CMIO board PCIe slot.
I do not know what could be the probable reason of failure.
Does this IC VL805, without flash memory, require firmware upload on each boot?

Hey, @geerlingguy , have you tested a 7x usb one?

It might work. According the the amazon page, it has a VL805 and a VL813 controller on board. According to this message, it might not work. https://www.spinics.net/lists/linux-usb/msg159005.html

So, it have 50% of working?

yes.. I need to know if the 7x USB with VL805 and a VL813 controllers works with CM4 IO Board. Can't wait for the findings..
