Arduino Leonardo: adapter_detect failed

[yamiro]

After my success with the Teensy I try to reach the same goal with cheaper components.
I ordered two Arduino Leonardo Ripoffs and two CP2102.

The firmware flash was successfull on both:

Code: Select all

avrdude -p atmega32u4 -c avr109 -P /dev/tty.usbmodemFA131 -D -U flash:w:atmega32u4.hex:i

avrdude done.  Thank you.

So I have 2 combinations: 2 Arduinos, each is connected to 1 CP2102. None is detected on my LTS14.04:

Code: Select all

~]$    gimx --config LogitechG27_G29.xml --port /dev/ttyUSB0 --status

I already changed RX/TX cables. Do I have to do anything special for the arduinos to work?

It looks like there is a bad contact.
Did you solder the pins?

[yamiro]

Yes, but the joints look OK. Small and shiny. The same to the second arduino.

[Matlo]

I tested a few of these cheap Arduino clones, and I had no issue at all.
Did you try different USB to UART adapters?

[yamiro]

No, I just reordered the same model from the same seller on ebay, which worked on my first project.
Are there any drivers needed to detect the arduino ripoff?
Is it possible that the flash went wrong even with a success message?
What is the minimal effort to get to know if the hardware works properly (Windows, OSX, Linux)?

Thank you in advance

Here's how to test the USB to UART adapter:
