USB 2.0 Extender & webcam

[fairm010]

Right...


Ive got a USB 2.0 Webcam on a USB 2.0 Cat5e USB extender... It says "Up to 50m range".

My length of cable is roughly 4-5 Meters... The webcam appears in device manager fine, drivers install fine, can see the image fine, for about an hour or so, at which point the picture freezes. So i close the window, and re-open the webcam viewer, and it says, cannot connect to the device, the device may alrady be in use.

Can anyone help?

Try using the camera without the extender, does it work fine then?

If that works with no issues, try using just a longer USB cable without the extender. 5 meters is a bit long for USB but a decent shielded cable may handle that.

It works fine without the extender.

I have several of these, creating a sort of cheapo mini cctv network. The Cat5e Extenders say up to 50m, so whats the issue? Really annoying!

So the issue is the extender. Try a different cable. Not all things work with all devices, or the extender can be bad.

Ive tried two different brands of entender. will try re-cabling between them!

As an afterthought im going to try plugging the host (PC) end into a powered USB hub before the PC, as i have a suspicion that the cam is losing power over the connection, espcially as these cams have 6 LED's on them.
