The card was easy to install and gives me more flexibility with additional USB ports. I have two USB 3 devices and now I don't have to unplug one to use the other device. I just wish more devices used USB 3 because it is faster. If you have Win 8 you don't need to install any driver for the card, the system will automatically find the driver.

I used this card to add 4 USB3.0 ports to my older XP SP3 machine. The hardware is very good for the price. Everything I've tried, including external disk drives, works well and has very acceptable USB3 speed with this card. The drivers on the supplied disk were a bit dated, but current drivers are easy to find on the internet. The supplied drivers work well enough, but I did have some problems with external hard drives waking properly from S3 sleep mode and hibernation, updating to more recent drivers for 'VIA USB eXtensible Host Controller' (specifically version 6.1.7600.4301 dated 9/25/2013) solved that problem completely, the supplied drivers and the updated drivers I found are neither digitally signed, but neither has produced any hint of instability on my XP machine. VIA is the only chipset I'd consider for USB3.0, and it does not disappoint, transfer rates are very good even when writing to two or more external drives simultaneously.

The expansion card is easy to install and so far has given me no troubles. All 4 ports are functional and do the job as required.
