USB max length is apparently 5m. At the moment, I have a 5m usb cable, and on the end of it my keyboard. My keyboard has an internal 1 port usb hub, which I have plugged my mouse into.
This setup works fine, 99% of the time - very occasionally they will stop functioning, but for the most part, it's absolutely fine. I previously had no 5m cable and it worked fine for a year. I have a slightly pricy intel motherboard.
I want to extend it to about 15m. So I bought some more 5m usb cables, and two powered hubs. I set my pc up as:
PC > 5m > USB hub > 5m > USB hub > Keyboard > Mouse
This worked, but every 3-4 minutes, the usb hub in the device manager would disappear, my pc would lag, and my keyboard/mouse would turn off. After about 10 seconds, my PC would lag again, and the devices would start working again.
The bandwidth usage in device manager for the USB devices showed as 1%, 2%, 4% presumably for the hub, keyboard, mouse.
I have tried switching out the cables for other cables, and I have tried these combinations too:
PC > USB hub > 5m > USB hub > 5m > Keboard > Mouse
PC > 5m > USB hub > 5m > Keyboard 5m > Mouse
I have tried using different ports in my PC and the USB hubs.
I am looking for either troubleshooting advice to narrow down the problem, or an alternative more reliable solution that won't cost a fortune. All help appreciated!
Wireless keyboard & mouse is a last resort :P
