Question Trouble with Recognizing USB-C Devices on ASRock Thunderbolt 4 AIC R2.0

[pangeng]

Hello Community,

I recently purchased an ASRock TB 4 AIC R2.0 card and installed it on August 4th. I don't have any Thunderbolt 4 devices to test its functionality, so I used the USB-C devices I have on hand. However, I'm facing an issue where none of the devices are recognized by my PC when connected to the AIC card. The same devices work perfectly when plugged into the USB-C port on my PC's chassis.

- Devices Tested:
LaCie Rugged Thunderbolt USB-C 4TB (via USB-C cable)
SanDisk Extreme Portable SSD (via USB-C cable)
Apple Magic Trackpad 2 (via Lightning to USB-C cable)

- Software and Controller Status:
Downloaded and installed "Thunderbolt (TM) Controller software ver: Rev86_3" from the ASRock TB 4 AIC R2.0 website.
Thunderbolt (TM) Controller software displays the following information:
Thunderbolt Software:
Application version: 1.0.34.0
Controller driver version: 1.41.1325.0
PCIe Tunneling: Enabled
Thunderbolt Controller 1:
Thunderbolt generation: thunderbolt 4 (1137)
number of ports: 2
security level: no security (SL0)
NVM Firmware version: 35.0

- Device Manager:
No errors reported.

- PC Configuration:
OS: Windows 10 Pro 22H2
CPU: AMD 7800X3D
Memory: 64GB Corsair Vengeance
Graphics: ASRock 7900XT PG
Storage: WD Black 4TB SN850X, WD Blue 510 4TB SATA SSD
Motherboard: ASRock x670e PG Lighting
AIC Card Slot: Plugged into PCIe #3 as per manual instructions
Jumper: Connected as indicated in the AIC manual
Internal Cables: Thunderbolt and USB cables connected according to the AIC manual

Has anyone encountered this issue or can offer some troubleshooting advice?

I’m having the same issue with the ASRock TB4 AIC and a B660 Pro RS MB. Can you elaborate on how the problem was fixed? All indications are that my hardware is working, but when I connect something simple, like a USB C external SSD, it is not recognized.

The internal usb2.0 pin was not connected corretly.
