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 article, the ExpressCard has an ExpressCard connector that plugs into a host, such as a personal computer, digital camera, or personal digital assistant (PDA), and the controller chip on the Expresscard uses a pair of differential Universal Serial-Bus (USB) data lines in the connector to communicate with the host.
Abstract: An ExpressCard contains flash memory. The ExpressCard has an ExpressCard connector that plugs into a host, such as a personal computer, digital camera, or personal digital assistant (PDA). A controller chip on the ExpressCard uses a pair of differential Universal-Serial-Bus (USB) data lines in the connector to communicate with the USB host, or can use PCI Express, Firewire, or other protocols. One or more flash-memory chips on the ExpressCard are controlled by a flash-memory controller in the controller chip. Two or more channels of a flash bus have a shared control bus but separate ready lines. The separate ready lines allow flash-memory chips in the two channels to finish operations at different times.

TL;DR: In this paper, a USB dual-mode microcontroller acts as a USB host, reading data from the removable flash-memory card and writing the data to the USB-memory key drive using USB packets.
Abstract: A flash-card exchanger has two modes of operation. When a host personal computer (PC) is connected to a Universal-Serial-Bus (USB) connector, the flash-card exchanger operates in a card reader mode, allowing the host to read data from removable flash-memory cards inserted into connector slots of the flash-card exchanger. When the host PC is not connected, a USB flash-memory thumb or key-chain drive can be inserted into a second USB connector. A USB dual-mode microcontroller acts as a USB host, reading data from the removable flash-memory card and writing the data to the USB-memory key drive using USB packets. Since the USB-memory key drive is small and removable, the user can upgrade to larger storage capacities by plugging in a larger-capacity USB-memory key drive. A flash-exchanger program executing on the USB dual-mode microcontroller copies data from an input-output bus and generates USB packets to the USB-memory key drive.

TL;DR: A smart card-host system as mentioned in this paper consists of a host, which has a USB interface, and a portable device, which provides smart card function(s) and a microprocessor for controlling data transfer between the USB interface and the smart card chip.
Abstract: A smart card—host system that operates without the intermediation of a smart card reader. The smart card—host system comprises a host, which has a USB interface, and a portable device, which provides smart card function(s). The portable device has a smart card chip for performing the smart card function(s); a USB interface for connecting the portable device with the host via USB protocol; and a microprocessor for controlling the transfer of data between the USB interface and the smart card chip, for converting data from a USB format to the format of the smart card chip and for converting data from the format of the smart card chip to a USB format.

TL;DR: A switch for connecting a desired peripheral to a desired computer uses a peripheral interface to translate either Universal Serial Bus (USB) or non-USB peripheral data to a common data format, the data is then routed to a computer interface as discussed by the authors.
Abstract: A switch for connecting a desired peripheral to a desired computer uses a peripheral interface to translate either Universal Serial Bus (USB) or non-USB peripheral data to a common data format, the data is then routed to a computer interface that translates the common data format to either USB or non-USB computer data.
