EMediaLive.com: Express Logic Introduces USB Support for ThreadX RTOS

Express Logic, Inc., a provider of royalty-free real-time operating systems (RTOS), announced USBX, a modularized, royalty-free USB communications stack for its popular ThreadX RTOS. Fully compatible with ThreadX, Express Logic's USBX eliminates the development, integration, and debug time required to write custom USB host/device support software.

Express Logic's USBX software allows application developers to create embedded systems that communicate via USB 1.1 and 2.0 protocols with existing commercial devices for data transfer and storage. USBX capabilities are useful for digital electronics products such as digital cameras, DVD players, medical equipment, 3G phones, set-top boxes, photo printers, MP3 players, and games consoles.

Supporting both USB Host and USB Device mode operation, USBX is composed of a core USB stack and a set of USB-IF approved USB classes that include mass storage, audio, printer, HID, and hub. USBX also supports popular embedded 1.1 and 2.0 USB controllers like OHCI and EHCI, found in the IP of many SoC devices and discrete controllers.

USBX works in conjunction with Express Logic's FileX embedded file system to support USB mass storage devices. USBX supports the USB 2.0 specification with OTG extensions. USBX is priced at $12,500 for a single-product development license with no run-time royalties. Broader licensing is also available.
