avrdude: ser_open(): can't open device "/dev/ttyACM0": Input/output error

[cao-huahua]

Hello, my arduino board is uno with ATMEGA 328P. Im using Arduino IDLE on my ubuntu desktop, apperanttly, something is going wrong. I just cant connect to arduino and I try to fix it by searching on the internet, discussions, comunnities but all the methods didnt worked for me. Is anyone of u had that kind of experience?

Oh, the last thing Id say is the last time Id used the arduino it was fine and I don`t remember anytime it was running on the ACM0 ports, generally, it was USB0.

I would been very grateful for the answers.
