Add new life to older desktop computers by providing them SuperSpeed USB 3.0 connectivity

The I/O Flex PU430 PCI to SuperSpeed USB 3.0 Host Adapter 4 Port brings new life to older desktop computers by providing them SuperSpeed USB 3.0 connectivity. The PCI card adapter is fully backward compatible with existing USB 2.0 and USB 1.1 devices, and connects with SuperSpeed USB 3.0 hard drive enclosures, SSD enclosures, backup RAIDS, video converters, printers, and hundreds of other devices while enabling the use of high performance device that were once reserved only for high speed buses like eSATA and FireWire. Able to offer most of the usable bandwidth of SuperSpeed USB, the PU430 is limited to a maximum of 2.133Gbps transfer rates [1] because of the limitations of PCI. However, that's an amazing improvement over USB 2.0, and the PU430 PCI USB 3.0 solution provides over twice (200+%) the performance gain over on-board USB 2.0, and is only 30% slower than the maximum speed USB 3.0 can achieve in PCI-Express (PCIe) slots.

The adapter provides four (4) external USB 3.0 ports. The I/O Flex PU430 PCI to SuperSpeed USB 3.0 Host Adapter features both 15-pin SATA power connector and mini 4-pin power connector for added power source to better support power hungry bus-powered devices. Easy USB installation makes adding new hardware a breeze, with no complex configuration, confusing plug-ins, or IRQs. Connect up to 127 USB products to PCs. Ready for use with self-powered devices, or plug any available 15-pin SATA Power Connector into the onboard connecter for devices requiring bus power.

Note on Elan P-Series Controllers

The Elan P-Series card readers have switched CardBus controllers several times over the years. While they have used Texas Instruments and TI compatible controllers, the changes in specifics sometimes cause issues. While not completely chronologically accurate, the following rough timeline should be helpful. Elan P-Series devices prior to 2002 used the TI PCI-1420 for their two slot readers and either the TI PCI-1410 or PCI1211 (depending on availability at production) on their one slot readers. For a stretch of several years (roughly 2002-2006) Elan used ENE Technology Inc. CardBus controllers in place of TI. The CB1420 for two slot readers and the CB1410 for one slot readers. A reliable, and widely support TI PCI-14xx clone series, ENE's controllers actually fixed many of the errata from the chips they cloned. This, however, caused problems for systems coded around the problems with the original TI PCI-14xx series. Around the beginning of 2006 Elan switched back to TI PCI-1420 for their two slot readers and either the TI PCI-1410 on their one slot readers. However, there still is a lot of ENE based P-Series readers in inventory, and certain models of the P-Series will not be replaced with the TI based controllers until the existing stock of ENE devices are sold.
