XM (requires an eXternal electro-mechanical adapter) – Technically the same as EM, but such adapter usually consists of 2 parts: a pseudo-card with pin routing and physical enclosure size that perfectly match the target slot and a break-out box (a card reader) that holds a real card. Such adapter is the least comfortable to use.
A USB-to-serial adapter or simply USB adapter is a type of protocol converter that is used for converting USB data signals to and from serial communications standards (serial ports). Most commonly the USB data signals are converted to either RS-232 , RS-485 , RS-422 , or TTL-level UART serial data.
MicroSD-to-SD adapter (left), microSD-to-miniSD adapter (middle), microSD card (right) A host device can lock an SD card using a password of up to 16 bytes, typically supplied by the user. [ citation needed ] A locked card interacts normally with the host device except that it rejects commands to read and write data.
The USB device class used is 0x08. Modern UDMA-7 CompactFlash Cards and UHS-I Secure Digital cards provide data rates in excess of 89 MB/s and up to 145 MB/s, [1] when used with memory card readers capable of USB 3.0 data transfer rates. [2] As of 2011, Secure Digital memory cards received an additional option of a UHS-II bus interface.

The card is composed of two detachable parts, much like a microSD card with an SD adapter. The small memory card fits directly in a USB port and has MMC-compatible electrical contacts. With an included electromechanical adapter, it can also fit in traditional MMC and SD card readers.
The ability to boot a write-locked SD card with a USB adapter is particularly advantageous for maintaining the integrity and non-corruptible, pristine state of the booting medium. Though most personal computers since early 2005 can boot from USB mass storage devices, USB is not intended as a primary bus for a computer's internal storage.
A USB card reader like this one will typically use the USB mass storage device class. A memory card reader is a device for accessing the data on a memory card such as a CompactFlash (CF), Secure Digital (SD) or MultiMediaCard (MMC). Most card readers also offer write capability, and together with the card, this can function as a pen drive.
