Parvus Corp. announced that it will soon release its new 4-port high-speed USB 2.0 host controller with two high-current USB ports for directly powering attached devices.

Touted to be up to 40 times faster that legacy USB 1.1 controllers, the USB104+ provides a total of four downstream ports, two supplying up to 500mA drive and two enhanced ports supporting up to 2A drive.

The press release said that the PC/104-Plus form factor (3.550-by-3.775-inch) module's high current power switches greatly simplify the power supply design of the embedded computer since the 2A ports can directly power attached USB mass storage and other devices through the USB cable.

The board's PCI-bus USB controller chip supports all hi-speed USB transfer speed modes such as high-speed (480Mbps), full-speed (12Mbps) and low-speed (1.5Mbps). All four downstream ports allow mixed, simultaneous connections of USB 2.0 and/or 1.1 devices at different speeds.

Target applications for the USB104+ board include use with various removable or fixed mass storage media, USB memory keys, printers, cameras, CD drives and high speed USB 2.5-inch hard drives. The device supports hot insert and is compatible with Windows XP Embedded, Windows CE, Linux, QNX and other RTOS.

The USB104+ is priced at $230 each in 100-unit quantities and is expected to be in stock by mid-Q1 2005.
