Can't install Arduino USB drivers in Windows 7 x64


I was able to install the driver in a Windows XP machine, but not in a W7 64 rig. At the beginning I could not install the driver because usbser.sys was not present, but I added it. Now the problem is related to the driver signature, I got a 52 code error.

Here's what says (the important part is CM_PROB_UNSIGNED_DRIVER):

How can I get around this?


that's happened allot with me, and i am using win32 now its better and more stable try to change Compatibility to win XP serves back 2 sometimes that's help

Hi narzan,

Change compatibility of what? The device is listed with a warning (!) mark in the device manager.

read this ;)

I've already done that, unfortunately. Could you please check if your usbser.sys is signed?

I'm currently running through a Linux VM on the same host...

ok then remove the drivers restart your pc, and do that again, don't forget to change the usb port to other one that's happened allot with me and i solve that with this stips if that's not work, sorry that's all what i know :P

Thanks for replying.

I already did that, I even used pnputil -f -d oem314.inf

I've tried with the 1.0.6 package drivers and 1.5.8.

Then format your PC XD i am kidding, wait maybe someone will help you in this ;) good luck

Thanks! I hope someone comes to help :slight_smile:

no one?
