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.
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.
