I am having the same problem, has anyone helped you figure it out? i just got recieved my first arduino in the mail and i can't even upload "blink" sketch. I have spent many hours researching if anyone had the same problem but have yet to come up with a solution. I do however have an "arduino compatable" DCcEle DCcduino UNO with the ch340g chip, and i downloaded the appropriate driver from http://www.wch.cn/downloads.php?name=pro&proid=178 and even followed the directions from this website: http://kiguino.moos.io/2014/12/31/how-to-use-arduino-nano-mini-pro-with-CH340G-on-mac-osx-yosemite.html which included going into Terminal and typing in a "sudo" command. afterwards i can see the arduino in available ports but still have the error message. my mac is running Yosemite 10.10. I have ordered a legit arduino leonardo to see if it works with that one but i wont have it for a few weeks. Any ideas?
Exact same error message:
avrdude: ser_open(): can't open device "/dev/cu.wch": No such file or directory
ioctl("TIOCMGET"): Inappropriate ioctl for device
Problem uploading to board.
