Digital Cameras Photo Reviews of D-Link DUB-H7 High Speed USB 2.0 7-Port Hub
Customer Review: 7-port fails, 4-port by same manufacturer works.
Summary: 1 Stars
I am an amateur astrophotographer since 1994, ham radio operator since 1957, software engineer since 1965 so I know astronomy electronics and software pretty well. I performed MANY tests where I needed to download images from a Canon EOS RebelXT camera. The D-Link 4-port hub that I have works fine. The D-Link 7-port hub that I bought does not properly allow download of the images from the camera. Instead of the full-frame images I get when downloading via the 4-port hub, I get a tiny 20x20 pixel image when using the 7-port hub. Tested this many times with different image download packages (CCDSoft, MaximDL.) Always the same results. The 4-port hub worked and the 7-port hub didn't. I then tried a competitor, the Aluratek 7-port hub. It was even worse. I could not connect to the camera at all. Tried these using both a desktop computer and a notebook computer. Same results.
I am thinking that the electronics for all the 7-port hubs come from the same source and they don't have it right yet?
I solved my problem (I needed 5 ports) by daisy-chaining a 4-port D-Link hub to a 4-port Gigaware hub. The 4-port hubs work fine. Camera images download fine even when the camera is plugged into a port of the second daisy-chained hub.
