How to identify "Multi Card Slot" hardware?


Hello :-)

How to identify "Multi Card Slot" hardware? The computer is a Samsung N150 netbook which has an optional "Multi Card Slot". Contacts can be seen inside the slot so the option is presumably fitted. According to the N150 manual it can read SD, SDHC and MMC cards.

There's nothing I can identify as a "Multi Card Slot" reader in /var/log/dmesg or messages and nothing in lspci or lsusb output. I'm no expert on such card readers so the device might be there and I can't identify it. There is a UHCI controller but isn't that only for Firewire?

I don't have any of these cards so cannot try booting with one plugged in until I can borrow one.

The reason for wanting to identify the card reader is that I'm building a kernel which only has support for the actual hardware.

AFAIK the N150 has no PCMCIA devices so I'm thinking to drop that from the kernel. Is it likely that the card reader is supported via PCMCIA in a similar way to USB drives being supported via SCSI?

Here's lspci output

It turns out the card reader is a USB device. This became apparent after inserting a card and checking /var/log/messages.

Further detail available via lsusb -vv (with -s if you want to filter the output) and udevadm info -a -p /sys/block/sd<letter>/sd<letter><number>, replacing <letter> and <number> with values shown in /var/log/messages.

Most of this information is about the device plugged into the card reader rather than the reader itself. Given that it "just works", details of the device itself are of little or no practical interest. For the record the reader's vendor is Genesys Logic, Inc. (idVendor=05e3) and the reader's product ID is 0727 which is a generically described as a "USB Mass Storage Device", presumably one of the products on http://www.genesyslogic.com/_en/product.php?classid=1
