Functionality Highlights
RTUSB-OEM supports both USB versions, 1.1 and 2.0. The protocol stack provides support for all major USB host controller types, including UHCI, OHCI, and EHCI based controllers.

RTUSB-OEM supports transfer rates of up to 12 Mb/s on USB 1.1 and 480 Mb/s on USB 2.0 buses, using low-, full-, or high-speed data transfers. All USB data transfer types (control, bulk, interrupt, and isochronous) can be used to support devices with both high throughput and real-time transfer requirements. RTUSB-OEM does not require data to be copied while being transferred. Data transfers are performed by DMA directly to/from the application’s buffer.

RTUSB-OEM performs I/O in the background by providing applications with the capability to start the I/O operations while performing other tasks. The status of this I/O transaction can be queried at a later time.

Class Drivers
RTUSB-OEM comes with high-level class drivers for keyboards, mice, touch
screens, printers and mass storage devices (disks, memory sticks, digital cameras, CD-ROMs, DVDs, etc.). A hub class driver is integrated in the core USB protocol stack. The class driver layer is are abstracted from the protocol stack for ease of use and portability.

Extreme Portability
RTUSB-OEM is designed to be easily ported to any platform. All OS and file system
dependent code is abstracted into a configuration file. This provides the application
programmer with an easy-to-use interface for porting any system dependent I/O,
memory management, and/or interrupt handling features.

Minimum Requirements
Any operating system and any file system for a mass storage device driver.
