Bild & USB Hub über USB-C Port der Grafikkarte?

Yes

Duo micro is an USB3.x type c pen

Okay, then probably I will need to make some adjustments for my card.

check in plist if you have the same device id

When I boot without the kext, I get this info:

So device-id looks correct.

yes like I have

I use this USB

After un- and replugging my usb-c cable USB 3.0 devices are also recognized

you miss an SSDT for hot plug I think (maybe)

Sorry I am confusing with other thunderbolt experimentation

All good, I guess the cable just wasn't connected properly.

I am having very poor speed of transfer though.

What app do you use to test the speed?

I just copied a small folder from external HDD to the desktop with about 1,2MB/s. On a different USB port I have around 120 MB/s.

It also takes a long time untill the HDD appears on the desktop, but this varies as well.

edit: the speed with Usb Stick is normal.

formatted in this way is pretty slow copying a 3.2 Gb dmg file on it

maybe it is fat32 (and ventura) related

try this ssdt without the kext (XHCI-AMD6900XT)

Lorys89 With your SSDT I don't get any connection at all.

This is with the Kext:

hackmac004 send log ioreg Using the kext, and I'll make you ssdt for your build

Thanks, that would be nice!

Zitat von hackmac004

Grazie, sarebbe bello!

prova questo senza kext

With this one it looks the same as with the one before.

I figured that the whole things works under Catalina without any kext or ssdt. I just checked again and there the external hdd is found, but is also slow. Pretty much the same behavior as in Monterey with kext.

Here ist the ioreg from Catalina, if it is of any help.

hackmac004

In Catalina?

Is there a 6900xt driver?

It was created in Big Sur 11.4 if I remember well

I know, thats right. There I only have vesa mode, but there the usb-c is working also as a hub.

Interesting if it is the gpu usbc
