SD card goes attached to Dom0 rather than sys-usb

[Franz]

Hello,

I noted that when I insert a SD card into the corresponding slot of my Lenovo x230, it is automatically attached to Dom0 rather then sys-usb (default configuration). Well I use the SD card only for my Nikon camera and I have no reason to trust Nikon less then Lenovo, so no problem for me, but wonder if this is expected behaviour.

Best

Fran

It's probably that the associated hardware device is not assigned to
any domU (e.g., your USB qube, if you use one). On my ThinkPad, the
device is labeled "PCI Express Card Reader." Assigning it to my USB
qube results in any inserted SD card showing up in the USB qube.

Issue for implementing an option to have this performed for the user
when the USB qube is first created:

Indeed may be a good idea. On the other hand, I remember that for some
Realtek devices it is impossible to attach the card reader to a
different VM than the (somehow bundled?) network card.

I guess it doesn't apply to your model, could you provide more details?
Also worth collecting info on problematic models to set appropriate
default depending on the hardware.

Not sure if I understand your question, but my SD cards are SanDisk Extreme 32 and 16 G

When I insert it in the slot an alert appears telling that it is attached to Dom0

if I digit lspci in dom0 nothing changes before and after inserting the SD card (so not sure how to follow Andrew suggestion)

If I digit lsusb in dom0  it gives: unable to initialize libusb: -99

ls /dev  shows addition devices mmcblk0 and mmcblk0p1, if I attach the first one to a VM using Qubes Manager, it works perfectly. Well it works now, years ago it did not.

I had card reader details in mind, not cards itself.

Take a look at kernel messages - you should have some hint about the
reader there.

Marek has already seen this, but for anyone else reading this, the
device lspci details are provided here:
