Herkese merhaba,
I’m using macOS Monterey 12.0.1 with Apple Silicon M1 iMac 24".
I bought Hama USB-C Hub, Multiport, 5 Ports, 2 x USB-A, USB-C, HDMI™, LAN/Ethernet (GTIN: 4047443436818) from Turkey at last month. As I read on both technical specifications and user manual, the USB-C port on device is bi- directional; it both supports PD and data transfer.
I tested this functionality both Windows 10 & 11 and macOS with M1 (Apple Silicon) chip. On Windows , the port works bi-directional perfectly. However, Apple Silicon device not support data transfer from port, supports only power delivery. If I connect a USB-C device from mac port directly, it runs perfectly.
I found this solution: " realized that I attached the hub to USB & ThunderBolt 4 port. Due to my M1 iMac cannot charged with PD, USB controller closes this port I think. After connecting the hub to USB-C 3.2 port, USB-C port on the hub was started working. This is not an issue, it causes from misunderstanding how the iMac ports behave."

I attached the hub to USB & ThunderBolt 4 port. Due to my M1 iMac cannot charged with PD, USB controller closes this port I think. After connecting the hub to USB-C 3.2 port, USB-C port on the hub is started working. This is not an issue, it causes from misunderstanding how the iMac ports behave. Issue is resolved now.
