This is my first post so be gentle. I'm not very computer savvy and this is probably so easy! My desktop Windows 7 Prof has 2 X USB ports at the front panel and 4 X USB ports at the back. I'm assuming that 'port' means 'plug'?
Anyway, from a USB port at the back I have a device connected by a long series of end-to-end Bluetooth extender cables into the back yard. The long cable operates in a very high temp environment and is not that reliable, but it works. To conserve its operability I wish to turn off/on the USB port ( and only this port) at the back of the computer (at a very inaccessible spot) when I don't need to operate the remote device (connected to solar panel inverters via Bluetooth). The computer is used for work, so I can't really turn it off. So summarising; how do I turn off/on one (and only one) USB port?

I've got as far as the 'Device Manager - Universal Serial Bus Controllers, but no further. There's plenty of stuff out there about turning on/off all the USB ports, but nothing about turning off/on one only. Thankyou for your help. Thankyou both. Have found the link and successfully downloaded USBDview. I've been trying it over the last couple of hours.
It seemed to work at first, but now I can't get it to turn off the USB port without rebooting which is not what I'm really after. I've tried using the non-administrator and administrator options with no luck using both 'disconnect selected devices' and 'disable selected devices' options, and one after the other in various combinations.
My USB boosted cable combo and USB port seem to hang-on regardless. I'll keep working at it though. I'm also wondering whether the USB individual port power supplies are even actually switchable in the electronics of the port drivers? But I'm in the dark really, knowing little about the semi-conductor hardware behind the plugs, or computers period. Maybe they're just fully powered all time regardless of any software changes?
Thanks again. Hi Phantom10. OK, I've tried that. And now I'm able to get USBDview to function as needed, and I'm able to toggle my (single) USB port on/off via USBDview by simply selecting 'enable selected devices' or 'disable selected devices'. I do not even need to select 'disconnect selected devices', which I wrongly imagined would be required.
The USB extension cable is turning on/off as required even when I'm logged on and all other used USB ports remain functioning normally. At first I needed to do a lot of rebooting to actually get the USBDview selections to 'accept', but I realised I needed to turn the solar panel software application off first, then it worked.
I guess the software was hanging onto the port somehow. So now I can power-down the cable when I'm working, like now. Or turn it back on when I need to check the solar panels, then off again!
Without having to physically unplug and plug the cable into the USB port. Once again, thankyou all for the suggestions. Problem is, I think, fixed.
