I just bought an Arduino Nano v3.0 (compatible? +- 5$) and I cannot connect it to my computer (Windows 8.1 64bit, Arduino IDE 1.6.8 installed).
The Arduino was bought as a clone but shows GRAVITECH.US on the front. It has a FTDI FT232RL chip (1412-G B8908572) on the back.
When connecting the Arduino the power leds burns the TX and RX led flash a few times (really shortly) and then die. Then the yellow L leds blinks once per second continiously.(power to the Arduino comes from the USB cable, not from external power)
In the system tray I get a message saying
"The last USB device you connected to this computer malfunctioned,
and Windows does not recognize it."
In the device manager I get a node under Universal Serial Bus Controllers:
Unknown USB Device (Device Descriptor Request Failed).
When examining the properties of the device, the device-status is:
Windows has stopped this device because it has reported problems. (Code 43)
A request for the USB device descriptor failed.
- I tried to reset the device
- I tried different USB cables
- I used another Windows 8.1 PC without Arduino IDE installed
- I used an old XP computer
All give same error.
I read about the bricking of clones by the recent FTDI drivers... I downloaded the FT_Prog tool V3.0.60 to check the PID, but the tool simply does not find the Arduino...
I'm out of ideas... does anyone have some left?
Thanks in advance!
