I have SageTV software and a Sage HD media extender. I am trying to setup my system. I would like to place my STB and Hauppauge HD PVR near my TV and media extender (in another room 45 ft from my PC). I want to do this because I have more room to place the large footprint STP in my media console cabinet, and little room around my PC.
To do this I need to connect from the HD PVR to the PC via a 45 ft USB connection. Can I buy two USB 2.0 to Fast Ethernet Adapters and connect them to my gigabit ethernet network to solve the problem of distance limits for a USB cable? This is the same network that everything else is using. I would attach one adapter to the HD PVR and the other to my PC. Will this work? Has anybody faced this problem? If this won't work is there any way I can make the USB connection? |

no.
Those USB to CAT5 adapters do not convert USB to ethernet. They just allow transport of USB over long distances using the CAT5 cable. You actually might sustain damage to your USB device, ethernet switch, or both, if you patch your usb to cat5 box into your ethernet switch. -Dan |

Is there anyway I can run some type of dedicated wire 45 ft that allows a USB connection?
How about a dedicated Cat 5e line with the adapters on both ends? Last edited by johnwmreed; 06-17-2008 at 06:17 PM. |

Funny I just got "USB Complete" book in the mail today.... It says that the max distance for USB is 16ft... but that you can get a max distance of 96 ft using 5 hubs. So you should be able to use 2 hubs and 3 16ft cables.

Great

I've read the timing and pulses get worse the longer the cables are (and are especially bad with cheap cables) so the hubs are needed to recreate the proper bits and clean up the pulses. |

I think you are right about needing power. The Hauppauge support people said they don't have experience with long cables.
I found a powered cable: http://www.usbgear.com/USBG-EXT-2X.html |

It worked!
I am using 2 16 foot long powered USB cables in series (total 32 ft) and the HD PVR works great.

I don't believe they need to be powered. Active cables are basically a max length cable with a 1-port hub on the end. The length limitation with USB is not an issue of power, but of timing. Each Hub provides the buffering/timing correction necessary to overcome this. The hubs themselves use very little power, and as such, a powered active cable is not really necessary. I'm soon going to be moving my sage client into a closet about 25 ft from my tv, and will be using a few active cables to keep my USB-UIRT and Optical drive at the set. I am thinking of using a USB audio dongle as well, to save the extra long spdif run. Biggest expense/limitation I'll be having will be getting the HDMI to the screen.

I've bought some inexpensive USB to cat5 baluns and use them to extend the touchscreen controls and wireless keyboard reciever from my server in a remote closet to a touch screen in the kitchen.
It works great for that type of application and only cost about $25 for the pair of baluns. However, I have not tried them with the HD-PVR. That device would obviously be sending a whole lot more data than the touchscreen or wireless keyboard. I'm afraid it might overwhelm the baluns. I'm glad the two cables worked out for you. That is probably the route to go if the distance isn't too great. The baluns are suppose to work up to 200'.
