Problem with USB-C PCIe card

[denkteich]

Hi all,

 

I have the following problem with this configuration:

OS High Sierra 10.13.6

Board: Gigabyte H370M DS3H

Processor:  i5 8400

Graphics card: GeForce GTX 1050

PCIe USB-C card: Sonnet Allegro USB-C 4-Port PCIe Card

PCIe FW800 card: DIGITUS, PCIe, Firewire 800

 

The system works fine as long as no usb-c drive is connected to the allegro. A USB-C drive connected to the boards usb-c is causing no problem.

 

If i connect a usb-c drive to the allegro the following happens:

- Drive Icons stay on the desktop, even if a drive is not connected, happens to all drive type (fw800, usb, usb-c)

- finder freezes if you try to unmount a drive

 

I tried a different USB-C card (BEYIMEI PCI-Express 4X zu USB 3.1 Gen 2 (10 Gbit/s) 2-Port, Asmedia-Chipset) with the same effect.

 

Does anybody have a suggestion why this is happening and how to resolve it?

 

TIA

the cpu can use 16 lanes pcie

the 1050 uses 16 lanes, the fw800 2 lanes, the usb-c 4 lanes.

 

is it possible that the problem is here?

Ok, any suggestion?

 

I discovered that disk utility is not starting when a drive is connected to the usb-c card.

plist iss attached.

I've put the card into my Catalina Hackintosh, it is not recognized at all. No drive is shown.

 

Is there any special entry in the plist to get usb-c card running in Catalina or high sierra?
