Windows 7 Unknown Device FIXED

Thanks a lot for the help.

Thank you! Tried to get my new UNO R3 working on Linux first and could not. Switched to Win 7 and was very disappointed to hit essentially the same error. Found your post and fixed right away. Thank you. Thank you. Thank you.

Might try to tackle Linux later, too, since this gives me some sort of hint on how to proceed there as well. Thanks again.

worked on 32 bit as well thank you.

Many thanks you are a lifesave, much appreciated help. Jim

Same problem with my new Arduino Yun on Windows 7. Thax for the fix :slight_smile:

Solved my problem. Really thanks!

I had this issue where the driver was not getting recognized. It turns out it was the USB cable itself. Make sure the cable is newer and not a USB 1.1 cable. As soon as I changed the cable it worked fine.

Also, when I tried to "force" the driver with the older cable it would blue screen. So if you get a blue screen when attempting this chances are it is the cable itself.

Wonderful !!
It took me 2 h to get my Arduino going.
I noticed the "unknown device" but I also have (after manual install) a "Ports&LPT" device - which has Error Code 10.
Now I still have a non working (COM5) port, but also a working COM6 !!

Thank you !!

/K

So I've tried this, and it's still not working. I even tried the "Have Disk" option, and it didn't work. This is the error I'm getting. Please help :c

Thank you! This option of moving the .inf file to Windows\inf really works for me. :slight_smile:

I don't even see the "Ports" option

this is my method on fixing my error, plz let me know if it is useful, thx...

all types of fixes i tried but didn't work.

It worked for 3-4 times, recognized the device with the selected driver. It did work as com port 8. After some time replugged MICRO to change the code; again same problem with driver :frowning:

tried the early methods and till now it's been around 37 trials to do the same method. even pasted the .inf in c:\windows\inf

both methods failed.. it says ".inf is not a x64 version"(reduced the big big sentences to meaningful conclusion)

i'm a newbie and fed up with just installing a driver.. if there is no method; i will change my win7 x64 to win7 x86. just say that it won't else i'm wasting my time.

thought of downloading an x64 version for win but not separate versions found in the download page.

Hi I am having the same problem like you but for win X 32 bits, i am getting the same error, I already post one on the forum, please if you solved it let me know how.

I have same problem .i can't fix code 10 error.Anybody help.

Win7 Pro failed to install Micro driver for me also. Swapped USB cable with a newer cable and Micro device drivers loaded 1st time I plugged the board in.

I have the same problem and I really don't know how to solve this issue. Can anyone please help?

this worked

thank you
