The installation was not easy or obvious. I am new to Windows 7, so that doesn’t help either.
I tried various forums with no answers that worked. This thread explains my problem:

Simply updating the driver with “Arduino UNO” on this Unknown Device did not work.
The device manager would continue to say no driver was found.
I the tried these 10 steps and it worked for me. Your mileage may vary.
Unknown Device Found.
Update Driver.
Choose “…List of Drivers”.
Choose “Ports”.
Choose “Arduino LLC” and then “Arduino UNO”.
Yes – Continue to Install driver!
Voila! Driver Installed.
Arduino UNO is now seen as a COM port.
And now, yes, Arduino UNO shows up under Device Manager.
Then, in the Arduino IDE, be sure to choose the new COM port!
Done.
Hi I’m having the same problem the only thing is I have followed all your steps up to the part where you scroll through the providers for the com port and arduino does not show up any help?
nevermind i made a dumb mistake.
I can’t see the arduino in the port manufactures either, what dumb mistake did you make??
You have to install the Arduino software first. It contains all the drivers. These steps just tell the device manager where to find the drivers.
could you tell me what the dumb mistake is cause the same thing is happening with me.
This worked like a charm, Thanks!
Same problem as Tim, I get Standad and below that there’s Brother. But no Arduino.
How did you get arduino?
Solved, just click the ‘Have Disk’ button on that stage and navigate to the drivers folder.
Glad it worked!
Excellent solution. Manufacturer and model were not on our list. But like Pritesh, we clicked “Have Disk” and got the driver that way.
Your solution enormously reduced consumption of aspirin while trying to install Arduino Rev3 driver on Windows 7. Thank you!!!
Great news!
I was able to make it work with your instructions. Thank you!
Works for me as well using Win 7 64 bit and an arduino Uno Rev. 3. To be explicit, after selecting ‘have disk’ browse to /drivers/ within the arduino IDE files. Select arduinoUNO.inf and then Arduino Uno. Click through the warnings and you should be good to go.
I already follow all guides as possible but my problem is different. My Windowns can`t recognize my arduino. No drives apeear on the list. What I have to do ?
By the way, this arduino have functioned on the same operational system on my friend`s pc.
Thanks
Thanks! Helped a lot
Awesome! Thanks you saved me a lot of time. I just got back from Radio Shaft as I needed to build an AVR programmer. I have an Uno already from Sparkfun, but this new one did not get picked up by the driver checks. I was wondering if they forgot to put the serial code on there!
Thank you, it helped a lot. And also the comments by Pretish and Neill helped. I didn’t have Arduino under the manufacturer list, but I clicked on “Have Disk”, went to the Arduino download file, drivers, and finally Arduino Uno Rev3. Thank you
problem solved…
thanks Very Much
Thank you! Great help!
Thank you so much! I was wondering what was wrong…
I did the same thing h20 did (used Arduino Uno Rev3) with Have Disk and it worked just fine!
thanks big help so far, but i run into a problem after Yes – Continue to Install driver!. it starts to load but then comes up with an error message, and it says This device cannot start. (Code 10). i a new to windows 7. thanks
Good job this work very fine…thanks a lot I was looking for solved many time
DUDE hats off!!!!the was the same problem for me too….with your trick and replys i could do it…..hackhut rocks…….
I had the same issue. You must have to show where the drivers are. It work like charm.
Thanks! Problem fixed
Mine still wont work i am working on a science fair can anyone help me out
I’ll try. What are you seeing in device manager?
thank alot,, so help full
hy, i just boght an arduino uno r3 and i install drivers, programm like you said (everything is working properly), but when i put the first example with pin 13 to blinking is doing the same even if i change values is doing the same is flashink every 5 sec on 5 sec off,if i uninstal the drivers is doing the same, i am doing somethig wrong? because i run out of ideas. many thanks
Not sure about that one. Could be your code. This might be a better question for the official Arduino forum.
Thank you! Nothing about this on arduino site. Been very frustrated! When following start-up guide from arduino site, windows fails at showing the driver file, and you’re stuck there. This worked great!
Thanks also! I also couldn’t found any working suggestion anywhere, but yours is working!
Thanks for this. I’ve now been able to instal the uno driver. However I still have another unknown device listed under USB controllers and cant connect to the arduino. Any ideas?
I am not sure. What I would do is just remove all usb devices from computer including mouse and keyboard. If you have internal bluetooth, use the bluettoth mouse. If you only have USB mouse, then plug that in. That should show up under HID devices. Then plug in the questionable Arduino device and see what comes up.
thanks, very helpfull indeed!
It doesn’t seem to be working for me. I can’t find a ports (com and lpt) section when i try the first step. could you help?
Hi Al,
Let’s see. Can you get to “Device Manager”? If so, I found my Arduino under “Other Devices”. When that branch is open, I found “unknown device” which was my Arduino. Verified it by unplugging it, sse ing the item disappear. Then plugged it back in and that item reappeared.
i tried all the above mentioned steps, but still my arduino driver is not installed. At the last step it shows “Windows found driver software for your devive but encountered an error while attempting to install it. windows unable to find the file specified”
Ankur,
I am not sure what to do. I am sorry to hear that you are still having trouble. Maybe someone else here can help you out.
Thanks for stopping by and good luck to you.

Thanks Roger for replying. Is it that there are different drivers for 64 bit and 32 bit ? I downloaded three different IDE versions for arduino, but still the problem persists.
Worked great! Thanks for documenting this
I’m getting the code 10 message. I’m pretty new to this. i’ve followed all the other steps for installing the driver. Help?
Sarah,
I don’t know if this is adware or not, but this was suggested to try:http://www.howtofixerror.com/ IT will scan and find the missing or corrupted files. Once you find those, you could try to re download everything and start again. LEt us know how it turns out!
Guys, not sure what the hell is up with this. I literally just don’t have the “Let me pick from a list of device drivers…” option. It isn’t there. It just isn’t there.
Please help.
Hi Zack,
Let me see if I can help.
When you open Device Manager, do you see the item “other devices”? Under that will most likely be “Unknown Device”. This is the Arduino. When you double-click this, it will open the driver update window. The bottom right button should say “Update Driver”. When you click this, there should be some option for you to select your own driver from your own location. Do you see that?
Maybe this way can solve your problem, I hope helping

Good find, Elliot.
Hi again, this is my solution it’s work for me
( found here http://arduino.cc/forum/index.php?PHPSESSID=8dd6743eaff6837e799ec60f4008f511&/topic,65956.0.html )
This is the source of your problem:
Opened INF: ‘C:\Windows\System32\DriverStore\FileRepository\mdmcpq.inf_amd64_neutral_774523d133de6343\mdmcpq.inf’ ([strings])
!!! sto: Driver package references a missing external file ‘C:\Windows\system32\drivers\usbser.sys’. Error = 0×00000002
You may need to enable Show hidden files, folders, and drives option in the explorer to follow the next steps.
Open file explorer window.
Select Organize -> Folder and Search options -> View -> select Show hidden files, folders, and drives
Open the archive: C:\Windows\System32\DriverStore\FileRepository\mdmcpq.inf_amd64_neutral_774523d133de6343\
Copy the file: usbser.sys to c:\Windows\System32\drivers\
Now try to install the UNO driver again. Hopefully this will fix your problem.
Under normal circumstances the driver installation process is supposed to extract the usbser.sys file from the Driverstore and copy it to the proper place. If it is already there, it will skip that step. On some systems, the extraction step does not happen and you get the error you are seeing. I don’t understand the cause of that.
