Windows 7 x64
firewall off
Port right
board right
driver reinstalled
I upload the sketch blink and he show me:
[quote]Binary sketch size: 1010 bytes (of a 32256 byte maximum)
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51[/quote]
i search on google and found nothing about "uno"
please Help :)
and sorry for my bad english

Ab29 2011-06-10 07:43:20 We do find cables make difference. One possibility is the voltage drop. Some usb cable are designed for signal transferring, the resistance of cable may vary. And the arduino is powered by usb cable, if the cable's resistance is to big, it will drop the voltage of Arduino and make wired problems, such as not able to burn the bootloader, etc.
Another possibility is the loose connection between the USB connector and cable. Try to tight the connection by any means.
Also, try another usb port and pc, if they all failed, we will suspect a faulty unit.

Maybe you can try a different USB cable. Many times a different USB cable makes a difference.
Let us know your results :) Hector
