Unable to Connect Arduino Pro Micro (ATm32U4DFU) with the Arduino IDE, Drivers Issue

Other Hardware 3rd Party Boards
1

Hi,

I am trying to connect Arduino Pro Micro (ATm32U4DFU) with the PC but cannot find the COM port on the Arduino IDE. When I checked the drivers for this device they were not installed. Could anyone help me to install the drivers as I have tried to follow the procedure given by the SparkFun guide to setup Arduino Pro Micro but the drivers are still not installed? Would be thankful if anyone can resolve this issue. I am attaching the screenshot of device manager window showing drivers issue.

Are you sure you got an original Sparkfun Pro Micro? You board seems to miss the Sparkfun bootloader but holds the Atmel standard bootloader. You might be able to upload code to that board using newer versions of avrdude (as they know the flip protocol used there) but it's much easier to change the bootloader to Sparkfun's version of Caterina.
Do you have an ICSP programmer available (may be an Arduino UNO using a special sketch)?

If you bought an original Sparkfun Pro Micro return it to your dealer for a replacement, but insist that you really get an original.

Hi, i have the same problem with my Pro Micro Heleigo ATm34U4
when i try to connect, on hardware resources (win 7), i can see 'arduino Leonardo on COM14, but few second later it isn't connected.
i tried to upgrade the driver, but the seems like an upgraded one is present.
i'm desperated.
no way to program the pro micro with Arduino IDE :frowning:

perhaps somebody say that i need IDE 1.0.1 to program my Pro Micro...
any idea?

I miss the link to this product. Google doesn't know it.

In that case you don't have the same problem. Push the reset button and upload within a few second a save sketch (p.e. Blink example).

It's not a driver problem, it's a bad sketch you uploaded.

Wrong, I just pictured one.

It's probably no Pro Micro if it shows up as a Leonardo. But that's only true for original hardware. That cheap Chinese stuff may be anything, it may work, but it also may fail at any time.
But I'm sure nobody will tell you to use the Arduino IDE 1.0.1 because at the time this version was current the Pro Micro didn't exist.
