Hi John, > Is there a way to make this SD card reader work with Mac OS X or Windows > guests?
As noted by Kevin here: http://lists.nongnu.org/archive/html/qemu-devel/2017-12/msg02765.html If your machine has a PCI bus you can plug it there: http://pcidb.net/view/1b36/0007 Linux kmod 'sdhci-pci' recognize it well. I don't know if OSX/Win guests have a such driver. If no, we could model the PCI7612: https://pci-ids.ucw.cz/read/PC/104c/803b Regards, Phil.
