SD card not read

[haaber]

I wonder why my Q4 notebook does not read my sdcard (well readable on my
+10y old dell430 running debian) - maybe there is some firmware
necessary/missing? How can I discover the concerned hardware (in which
VM? in dom0 ??? sys-usb?) Thank you, Bernhard

You should see your device in the output of `lspci` in dom0

For instance:

02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5227
PCI Express Card Reader (rev 01)

On my setup this device is assigned to sys-usb. I can mount the SD card
there ; attaching it to another VM with the help of the device tray
works well too.

Your reader may also not work because:
- it's disabled in your bios
- your laptop's too recent and it's not supported
- it's buggy
