I come here with a problem that I haven't been able to solve after various tries:
I work on a computer with KDE neon (latest verion - 5.26) in a DELL Precision Tower 7290, in which we asked the company to add a PCI Thundebolt card (0000:03:00.0 PCI bridge: Intel Corporation JHL6540 Thunderbolt 3 Bridge (C step) [Alpine Ridge 4C 2016] (rev 02) (prog-if 00 [Normal decode])). This week, we wanted to install the 10gb network adaptor by QNAP QNA-T310G1S, which should be connected on the Thunderbolt port.
I first tested the QNAP adaptor in my Windows computer, and it worked fine, so the hardware is ok, and then I tried in the KDE computer. However, I can't make it work.
Until friday, I was connecting to the thunderbolt port and on dmesg I was getting the message below. It wasn't showing as a new device being added/authorized:

I tried installing the drivers according to the company's instructions (i.e. using this driver), but not working. I'm wondering if instead could be a problem with the Thunderbolt card itself...
So, I followed the instruction in this post (changing the GRUB_CMDLINE_LINUX_DEFAULT); and It improved: the device is now recognized, but not completely. I still get this message:

Would anyone be able to help me?
