What is wrong with my Uno r3? Answered

Please help.  I have 5 UNO R3 clones and I can't install them on my computer. When I plug them in two red LEDs light and the board comes up under Other Devices as a USB V2 device.

I've tried every driver I can find, but none are recognized as suitable. I've tried 5 different boards, two computers Win 8.1 and Win 7. I've swapped cables and still nothing.

I have a feeling it could be a lack of a bootloader on all the boards. How would I check if this is the case and how would I fix it? I have managed (easily) to install an Arduino Mega with no problems and I've managed to install many other devices so it's not a case of too dumb. Just a little dumb :-)

Any help would be very much appreciated.      Stu

My fault for buying cheap and nasty Chinese knockoff's. I purchased an original Arduino Uno R3 and it installed and worked straight out of the box. Anyone want to buy 5 barely used Chinese copies ? :-) Plus about the same in Nano boards as well.

Maybe worth trying to use the right driver for the clones?

If you can find one which works I'll buy you a beer. .... No I'll buy you 2 beers. I've tried every driver mentioned by Google and believe me it's not just a few. Even the drivers especially for Chinese Clones. Then again I had a go at installing Windows 10 last Friday and I caught what's know as the "Impossible Password Syndrome" After rolling back to Windows 8, I tried again and the whole affair crashed. So I then rolled back to Win 8 Again and MS kindly (without my consent) upgraded me to win 8.1. Maybe one of those drivers may work now. My previous Win 8.1 was in a horrible mess, so maybe I should give it another try. ???

I know that since the "bug" for the serial chip clones have a hard time.
Many sellers now include a link for the right driver as there are several different chips out there.
In some cases users claimed it never worked on their system because the driver insisted on a specific Com port that was already in use.
Of course the installation stopped with some asian error message.
On a clean system I would give it another go, check the serial chip for markings - if you are lucky it helps to find a driver for that chipset, which is easier than for a specific Arduino clone ;)

If you have a link specific to the clone boards (or manual, etc.), include that here. Maybe there's a jumper or something that's an added "feature" not present on the official boards.

When you run the IDE do you see them under the COM ports? Just search for burning the bootloader on an arduino, there are many methods to reflash the arduino. Good luck.

No it doesn't register as a com port only as a USB2 device. I've noticed some of the boards have one steady red LED and one flashing and others have two steady red LEDs. I'm not sure if this means anything. I've tried something like 12 different drivers, all recommended by other users but none work.
