Hi:
In this xps 15z laptop Im having (another) weird problem, Initially I thought that the MMC card reader was not supported as this fact was mentioned in some wikis.
However it works well, BUT only when a memory card is present at boot time, otherwise the device never shows up, it disappears from lspci, modprobing the needed drivers have no effect.
It is kinda like the PCI device is powered off at boot and never comes back when a card is plugged in.. what could be causing this issue ?
After writting this message I did a reboot with a card inserted, and the following info about the controller is shown
