![]() ![]() GENESYS LOGIC USB HUB DRIVER FREEThese can be had for about $12 a piece, and if you have free PCI-e x1 slots, it’s definitely a possibility. It’s probably something not often practiced – but you can solve the lack of ports issue with a PCI-E to USB 3.0 adapter. But now more USB 3.0 devices can be had at reasonable costs – sometimes even at the same prices as their USB 2.0 bretheren – doesn’t it make sense to have more ports? To hub, or not to hub?īefore I actually review the device in question – we should probably review whether having a hub is a good idea in the first place. It’s a small price to pay for a drastic increase in performance – no longer are we restricted to seeing rates of 35MB/s and below (sometimes quite significantly lower) when talking to external USB hard drives – we can now attain sequential rates limited by the spinning media in such drives even without UASP – and with UASP to overcome problems with command latency and lack of queueing in the older Bulk-only Transport mode of mass storage, performance improves even more!īut there was always one thing nagging me – while USB 3.0 is obviously great, and the host ports are backward compatible down to USB 2.0 and 1.1, USB 3.0 ports are always rather scarce! I guess we can put this down to cost cutting on behalf of the chipset makers and motherboard manufacturers – high speed USB 3.0 PHYs were not easy to make cheaply, at least initially. the USB 3.0 B-connectors will not mate with USB 1.1/2.0 B-sockets In order to do all of this as cheap as possible without breaking backwards compatibility – they had to introduce a new row of conductors buried inside the A connector and straddling on the side of the various types of B connectors creating cable-compatibility issues – i.e. USB 3.0 ups the physical layer rate from the 480Mbit/s to a more reasonable 5Gbit/s – and is on its way to 10Gbit/s, while alleviating shortcomings in power delivery by upping the current limit from 0.5A to 0.9A without the battery charging/supercharging extension. Genesys Logic also announced it is developing 10G SerDes technology that can be used in the upcoming 10G extension of the USB 3.0 standard.Compared to USB 2.0, USB 3.0 is a miracle long overdue. The G元520 supports both individual and gang mode and is available in QFN 88-pin and QFN 64-pin package. Its firmware is upgradable and configurable based on customers’ needs for features such as the number of downstream ports, compound device and GPIO settings. Featuring built-in 5V to 3.3V regulators uses patented Smart Power Management to dynamically switch the operating mode of downstream ports to ensure the quality of data flow. The G元520 consumes 0.9W of power when all four downstream ports are operating with SuperSpeed devices. GENESYS LOGIC USB HUB DRIVER PCG元520 meets the expansion requirements for peripherals but also achieves high data throughput and power efficiency in PC docking stations. The G元520 USB 3.0 Hub controller with USB 3.0 PHY is designed for applications such as PCs, monitors, docking stations, retails, digital TVs and home entertainments. ![]() Genesys Logic's USB 3.0 hub controller, G元520, was certified by the USB Implementers Forum (USB-IF) for SuperSpeed USB Hub.
