Of course, an SD card can be made to look like a USB stick just by sticking it in a card reader.
I guess you mean "in a USB-to-SD card adapter", which translates a SD card into a USB mass storage device (/dev/sd*). A SD card reader such as the one the OP has just exposes the SD card as what it is, a SD/MMC card (/dev/mmcblk*).
