where may I find logs for USB controller

[Franz]

Hello friends,

I bought a PCIe USB controller card, which is advertised to work with linux.

It is Sonnettech Allegro Pro 4 USB 3.2 Gen 2 Type-C.

On my fully updated system, lspci shows the other USB controllers, but nothing about Allegro. So I wrote to Sonnenttech and they asked for the logs to study them.

Due to the peculiar nature of Qubes that hides USB controllers from dom0 (lsusb reports no USB device) I am confused about which logs may be useful.

Any idea?

Best

Franz

In the sys-usb "qube settings" go to devices and see if sys-usb is
allowed to "see" your device. Maybe you did that already, maybe not :)
