I've been looking for a long time to find out why some USB hubs cost over $100, and some only about $15.
I've checked the specs on the expensive ones next to the cheaper ones, and can't figure out what's so different.
For instance, a Digi Hubport 7port hub costs $128 to $138. It has USB : 4 x 4 pin USB Type A,
USB : 1 x 4 pin USB Type B interfaces, and
4 USB 4 pin USB Type A,
1 USB 4 pin USB Type B free ports.
# UL, CE compliant,
USB Data link protocol,
12 Mbps transfer rate.
Another, the StarTech 7 Port Compact costs $13.38 to $30. It has Hi-Speed USB : 7 x 4 pin USB Type A,
Hi-Speed USB : 1 x 4 pin USB Type B interfaces, and 7 Hi-Speed USB 4 pin USB Type A,
1 Hi-Speed USB 4 pin USB Type B free ports.
# FCC, RoHS, CE compliant
Hi-Speed USB Data link protocol
480 Mbps transfer rate
Both are externally powered. Maybe I'm wrong, but it seems as though the cheaper one is actually better. What's going on? Thanks.
