PCMCIA USB 2.0 Cards & Linux Lite

<< < (3/3)

Hello, All!

Some of my older laptops have only one USB port, or support only USB 1.1. For the Dell Latitude C640, both of these apply. At the same time, the C640 also has one or two unused PCMCIA slots available.

Having found a cheap used PCMCIA 2.0 card at my local computer surplus store, I stuck it into the C640. The Linux kernel recognizes and supports these cards, or at least the one I purchased - a Zonet ZUN2200.

This card adds two USB 2.0 slots.  This offers a 10X increase in the USB data transfer rate, and allows the use of newer USB 3.0 devices at USB 2.0 speed, as many USB 3.0 devices won't work on USB 1.1 ports.
 
For high demand accessories, the card also supports a plug-in cable to power the new slots from the USB 1.1 port, or an external 5 VDC power supply...
