From time ago in order to update the firmware the ttyUSB0 port in LINUX gives me the next errors:
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x0f
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x4d
avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x58
avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x49
avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x49
avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0xc8
avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x28
avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x04
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0xae
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xec
In WINDOWS i can update the firmware without problems.
In PRONTERFACE gives me the next error:
[ERROR] Can't read from printer (disconnected?) (SerialException):
device reports readiness to read but returned no data (device disconnected?)
7.1 /0.0 B:27.5 /0.0 @:0%
Printer is now online.
/0.0 B:27.5 /0.0 @:0%
But when I turn the printer off and on again, appears the ttyUSB1 and all is good.
What could be?

Hi,
I always exit Pronterface before powering-down the printer. This assures the existing port is closed.
Do you have other Arduino-based hardware connected to your PC? That has been known to cause all sorts of unusual effects when attempting to update firmware.

Thanks Neil.
I tested with another linux machine (debian8.1 on beaglebone black)
and I could upload the firrmware without problems through /tty/USB0.
Moreoever, when I tried to compile and load with
ino package, I found the same error. I get back to the graphical arduino IDE
and everything is working fine now.
I suppose that my original problem is concerning to bad procedures like
Neil says, for example: power-down the printer without exiting Pronterface.
