Overview of EP-USB66
The EP-USB66 is a complete IDE and USB solution for the most demanding
hardware configurations. A combination UltraDMA-66 EIDE controller and Universal
Serial Bus (USB) Hub makes the EP-USB66 a superb addition to any PC based
system.
UltraDMA-66 Controller
The UltraDMA-66 portion built using the advanced HPT-366 PCI Host Adapter chip
is capable of up to 133 MBytes/sec burst data transfer rates on the PCI Local Bus. The
HPT-366 supports a wide range of devices such as CD-R, CD-RW, DVD, ATAPI CD-
ROM, LS-120, Tape and ZIP devices. The controller also of course supports today’s
faster UltraDMA-66 hard drives as well as being backwards compatible with
UltraDMA-33 and PIO mode transfer rates. The controller has two IDE channels than
can support up to two EIDE devices each plus the card can coexist with any EIDE
controllers onboard your motherboard. Setup is completely automatic as the card will
autodetect the best possible transfer mode for each attached ATAPI or EIDE device.
UltraDMA-66 Controller Features Summary
• Sustained transfer rates of up to 66 MBytes/sec.
• Up to 133 MBytes/sec burst data transfer rates on the PCI Local Bus.
• PCI 2.1 “Plug & Play” compatible.
• Can coexist with other IDE and SCSI controllers.
• LBA translation and Extended Int 13 support.
Universal Serial Bus (USB) Hub
USB is made possible by using the Texas Instruments TUSB2046 4-port USB Hub
chip. The chip includes full USB version 1.1 compliance and creates a self powered
USB Hub on the EP-USB66 PCI card. The Hub works in conjunction with your
motherboard’s (or USB controller card if present) USB port to add a total of 4 useable
ports for USB devices. This is in addition to any available USB ports that your
original USB controller has left unoccupied.
Universal Serial Bus (USB) Hub Features Summary
• USB version 1.1 compliance
• Self powered Hub
• Coexists with onboard USB controller via loopback USB cable
