TL;DR: A flash memory card reader reads and writes multiple types of flash-memory cards, including CompactFlash, and the smaller SmartMedia, MultiMediaCard, Secure Digital, and Memory Stick as mentioned in this paper.
Abstract: A flash-memory-card reader reads and writes multiple types of flash-memory cards, including CompactFlash, and the smaller SmartMedia, MultiMediaCard, Secure Digital, and Memory Stick. A converter chip converts the different card signals for transfer to a host personal computer (PC). Serial-to-parallel data conversion is performed for the smaller card formats with serial data interfaces, but not for CompactFlash with a parallel-data interface. A single slot has a 50-pin connector for CompactFlash cards or passive adapters. The passive adapters have the CompactFlash form factor and a smaller connector fitting smaller flash cards. Passive adapters have no components but simply wire the smaller connector to the CompactFlash connector. A pin mapping allows card-type detection by sensing the LSB address pins of the CompactFlash interface. A larger CompactFlash reader has multiple slots for each card type. The reader is connected to the PC by a cable, or located within the PC chassis in a drive bay. A stand-alone reader copies images from the flash-memory card to a removable disk media. Pressing a button initiates image transfer.

TL;DR: In this paper, the authors proposed a solution to provide a computer system equipped with a USB (universal serial bus) device with a security function, comprised of the USB device having a security functions and a computer capable of using the USB.
Abstract: PROBLEM TO BE SOLVED: To provide a computer system equipped with a USB (universal serial bus) device with a security function, comprised of the USB device having a security function and a computer capable of using the USB. SOLUTION: A personal computer (PC) 10 has a client software 11 provided with an ID storage part 16, a USB host controller 14 and the like. The USB device 20 has a peripheral equipment interface 21 to achieve an intrinsic function as peripheral equipment, a security interface 24 equipped with an ID storage part 27, an interface control part 25 to control the peripheral equipment interface 21 and the security interface 24, a USB bus interface 23, and the like. By the time when the use of the USB device 20 get authenticated by the PC 10 based on the comparison of IDs of both sides, the state of the security interface 24 becomes to be able to return a descriptor and the state of the peripheral equipment interface 21 becomes not to be able to return a descriptor.

TL;DR: In this article, a method and device are disclosed for detecting successful transfers between a USB port and a USB smart card and generating a signal that provides an indication of the USB transaction activity.
Abstract: A method and device are disclosed for detecting successful transfers between a Universal Serial Bus (USB) port and a USB smart card and generating a signal that provides an indication of the USB transaction activity. This USB transaction activity signal is modulated according to the USB transaction activity and drives a Light Emitting Diode (LED) in a preferred embodiment of the invention. A counter internal to the USB smart card scales the transaction activity signal such that it is perceptible to the user. Because the current through the LED depends upon the USB transaction activity, the brightness of the LED varies according to the USB transaction activity. The LED may be driven from a current mirror sink or source, or a current switch sink or source.

TL;DR: In this article, the drive can be detected via any of the usual interfaces, IDE, ATAPI, USB or 1394 to the host unit, and the expansion slits are designed for use with different type of memory card, such as type I, II and III PCMCIA or PC cards, compact flash cards, smart media cards, multimedia cards, memory stick cards or secure digital cards.
Abstract: Drive comprises one or two insertion opening (21, 22) in which different expansion slits (30, 40) can be inserted. The expansions slits are designed for use with different type of memory card, such as type I, II and III PCMCIA or PC cards, compact flash cards, smart media cards, multimedia cards, memory stick cards or secure digital cards. The drive can be detected via any of the usual interfaces, IDE, ATAPI, USB or 1394 to the host unit.
