Quote:Quote:...The device I am using is the USBgear 4 port over IP hub:http://www.usbgear.com/USBG-4NET.html...That device only supports isochronous mode at USB 1.1 full speed (12 Mbps).If your device requires USB2 high speed (480Mbps) in isochronous transfer mode, you are out of luck.RE: Belkin router with USB port...It is not designed for USB protocol translation nor able to sustain high-speed transfer (independent of any firmware). Do not waste time on that, unless only want to use it for very basic/trivial functions.The U (Universal) in USB is a difficult term to qualify and has trapped many. Put a low-end/less-demanding device, in many cases, cheapie implementation could work. Put a high-end, most-demanding device on a work-around (with corner cut as a partial implementation) system, it fails miserably.Follow the spec. is the only assured way to get it to work 100% of the time.Clear Skies!ccs_hello

Quote:No worries. How long a string of USB 2.0 repeater cables did you use? I am using 3 currently without a problem... But for my new site I would probably need 6 or 7 of the 5m USB2.0 repeater cables... I am not sure that would work, although it would be a cheap solution...
Quote:website info and spec sheet do not match.
I can agree that the Ethernet port can support gigE (per other part of the web page).
But I doubt it supports isochronous transfer mode at high-speed (480 Mbps).

Can you run a benchmark speed test on your device? If you stick a USB flash drive on one of the USB ports and roll out 100ft of cat5 cable then try this little program and run the speed test.
I have used this to test the speed of my 5m repeater cables and my USB 1.1 dongle over 100ft of cat5. For my purposes, to get video from my capture device back to the computer, e USB 1.1 fails. Then again, measuring the speed of my USB ports on the computer and out on 45 ft of repeater cable plus a powered hub was almost the same. I think if you test the speed of your device over the 100ft distance and then compare it to what speed you achieve on the flash drive plugged directly into the PC USB port it would be very helpful.

Quote:great work Mitch. Looks like a string of USB repeater cables is hard to beat unless you need to go much more than 100ft. (especially when you consider cost!). Al
Quote:Mitch, thanks for the analysis. Certainly suggests to me that using a long USB repeater chain is the preferred method. One question I still have, I think it was ccs_hello who said that there was a limit on the number of USB repeater hubs you can have. Is this a limit just for XP? Can windows 7 handle more than that? I also think he said a 7 port hub counts as two repeaters? So how can you get to 25m using the tether pro cables? That would suggest 5 5m repeaters plus your hub... Hopefully the answer is that there is in fact no limit on e USB repeater chain?I also have a 100ft cat5 and USB dongle set, but I only use that for low speed devices like GPUSB ST4 box and USB to serial for planetarium or nexRemote. Interesting I tested plugging in is 100ft USB 1.1 into my USB 2.0 hub and testing the speed on three 5m repeater cables. Funny enough I clocked consistent 992kbps on the USB 1.1 irrespective of where it was plugged in. However the USB 2.0 repeater cables averaged 19Mbps to 23Mbps depending on which port I used on e hub. When I did not use the slower USB 1.1 plugged into the same hub, I achieved closer to 24Mbps, but only on one of the 4port hub connectors. Net, net my setup is probably just going to continue as it... I ordered another 2 5M repeater hub cables, so I will have 5 segments and two hubs, one hub after 2 segments and another hub at e end of segment 5. I will drive two telescopes and 3 cameras. Let's see how it goes,Al
