TerraMaster Forum

Not always, but very frequently TerraMaster D6-320 is recognized by my OS (Linux on an Intel NUC11) as a slow USB 2.0 device, even if connected with the included pure USB-C cable. This happens even if D6-320 was previously recognized as fast 10gbps USB 3.0 device on same port. After a simple soft reboot of the OS, it suddenly appears as USB 2.0 (see screenshot). To make it reappear as USB 3 I need to unmount all filesystems and reconnect device in another port, which will go back to USB 2.0 after a plain reboot. In my NAS scenario this is unacceptable and very annoying.

Please advise how to fix this on Linux without the "connect it to Windows for a while" solution that I've been reading through this forum, which is unacceptable and impossible for me.

Curious as to what flavour of linux you are running?

Fedora Linux, latest version with all updates.

Here is another screenshot with USB Viewer tool

In the existing feedback cases, some customers have encountered the same problem as yours, we suggest you refer to the following methods.
The reason is most likely that the USB interface signal of the NUC host is interfered, and you have to add a USB-C docking station to transfer, so that the portable hard disk enclosure can recognize USB2.0.
It is recommended that you add a USB Type-C docking station to use together.
