Can not use Realtek RTS525A PCI Express Card : Unsigned class [ff00]

[Laurent]

Hello,

I've just installed Qubes OS on my laptop (Dell Precision 5510) and I'm not able to use my PCI Network card :

lspci (on Dom0) return

I tried to add this device to my sys-net

PCI Express Card reader (rev01) is an SD card reader, not a network card.
Can you provide the full output of lspci?

Oups !!! Sorry for this mistake ..

No problem! The only network card I see in that list is the same one you
already found-

02:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a)

Is Ethernet built in? Do you need to enable it in your BIOS? Are you using
a USB Ethernet adapter?

[Laurent]

Yes, I use an USB Ethernet adapter (USB type C):
https://www.amazon.com/Dell-Dbqbcbc064-Adapter-Usb-C-Ethernet/dp/B01BQ8RU2U


I've the same issue with my hub USB (type C also) :
(https://shop.hardware.fr/fiche/AR201511130055.html?gclid=EAIaIQobChMI_4bM8tHR1wIVdSjTCh2HWQSyEAQYASABEgLnqfD_BwE)


My USB flash drive works fine when directly plugged on my laptop. When using my Hub, the same USB flash drive is not detected.
Same for an external USB Disk Drive.

USB devices are handled differently. See
https://www.qubes-os.org/doc/usb/. If you are only using the Ethernet
adapter occasionally, try doing a passthrough of it to your NetVM as
described towards the bottom of that link. If you need to use it all the
time, you could assign one of your USB controllers to the NetVM but note
each USB controller handles specific physical USB ports.

In dom0, try lsusb and qvm-usb to see if they are showing up anywhere.

Did you figured it out Laurent? I have the very same problem with the very same adapter...

Same thing happens with DELL DA 300 also. I have seen it working once, but not sure how it happened and I couldn't make it work again... so I know is possible!

Thank you in advance.
Best.

I made it work using permissive mode, although I don't think it is really needed. Now I'm having the unplugging/plugging issue described here: https://groups.google.com/d/msg/qubes-users/WMc88pfT-hM/S1Q4esFyEQAJ
