Review on 🔌 Syba 2x Serial RS-232 RS-422 RS-485 DB9 Ports ExpressCard - Reliable Data Transfer & Connectivity by Sam Bhushan

I bought this express card to have USB 3.0 in my old DELL Studio XPS 1640 laptop. When I opened the packaging, the first impression of this card was not very good. I put it in my Express slot hoping the drivers would install automatically, but my Windows 7 couldn't see the device. I used the CD that came with this card to install the driver but nothing happened. Then I searched online for the latest drivers for this device and installed it, but even then the card was not recognized and my computer said DING (Express card connected) DONG (disconnected), DING DONG, DING DONG it showed that the Express -Card was not properly connected. I held it with my hand to stop the ding-dong noise and I succeeded, but the card wasn't recognized. I also tried connecting after applying an extra 5 volts but after wasting 2 hours of my life I decided to waste it. Please do not buy this product. I will buy a new computer with USB 3.0 next year instead of spending so much money.
