Hey guys I'm looking to get a long usb cable to use the zwo cam on my rig. I think I've seen it mentioned before about max usb length is 5m… and stuff about usb1.1, 2.0 and 3.0 but couldnt find it here.
My PC has both usb 2.0 and 3.0 ports and i would like to get the best i can... but some of the prices of the 10m usb 3.0 cables are stupid! Would it make any difference if i just go with a 10m usb 2.0 cable?

USB3 cable will only be of an advantage with a USB3 device. Otherwise it will operate just as a USB2 cable on a USB2 device. I have managed to get USB2 and even USB1 to run happily over a distance of 30 metres (about 60 feet) by using cables with a Booster built in. But you have to have the Booster at the right end of each cable for it to work well. The Booster must be at the far end of each cable looking from it's powered end. From the laptop or PC the Booster must be at the far end, then the next cable must have it's booster also at it's far end, and in my case using 3 x 10m cables, the third one also has it's booster at it's far end. Hard to mix them up because the tail end of one fits into the booster of the next. But where you might run into problems is the quality of the cables. A lappy or PC will shove 5 volts down a USB cable. Any loss at the Computer end (like even 0.1 volt) can be a serious 0.5 volt loss at the other end. Some devices refuse to operate if they don't get their full 5 volts. There are some USB imaging cameras that fail to work if the voltage drops to 4.9 volts! Here is a 5m boosted cable www.scan.co.uk/products/5m-scan-usb-20-cable-type-a-(male)-to-a-(female)-active-boosted-extension-cableHere is a 10m boosted cable www.epostraders.co.uk/10m-usb-2-0-a-male-a-female-boosted-extension-cable-black.htmlAnother method to boost the signal over distance is to use powered Hubs at each join

Hi I have joined two 10 metre boosted USB cables to run a CCTV camera. This type of camera also triggers an alarm should an area be disturbed, (Garage Door, out of sight from house). No problems at all, even though its running on a second monitor 24/7. Cheers Pete.

Don't know what happened there. Only pressed 'Post Quick Reply' once.

Hi All, I discovered one thing about USB ports (Quite by accident). If you are using a Desktop, the USB ports at the back of your computer, (nearest the Motherboard) are more powerful than the ones in the front.
If I use the front ports on my CCTV, I can't engage to built in alarm. No problem using the rear connections. At first I thought it was only my make of desktop, but when I mentioned it in another blog, it seem to apply to most makes.
Not sure with Laptops
Cheers
Pete.

Wouldn't make sense in my laptop Pete. It has 2 USB's on the left and 1 on the right. Not front and back

Hi Ken, I bought a nifty accessory from EBay for my wifes laptop. Its a USB Amplifier. One inlet, 4 outlets. I have used it to run my Opticstar, mouse and USB/serial adapter with plenty of power and no problems to report. I bought it about 3 years ago so I can't remember the purchase details. Cheers Pete
Edit::: Used a default driver for the adapter.

Hi Ken / All, Basically it is a Hub, but this one comes with a couple of guaranties. 1 = Each outlet port has a signal amplifier. 2 = The signal maintains a constant output, no fluctuation. Unfortunately the packing box, with all the details and make, has long gone. All it contains on the device itself is 'USB Amplifier', in English and Chinese. (Yup, probably a copy. ) Perhaps most hubs do the same, never checked. Cheers Pete
