I have a strange problem with my serial port. It seems that sth has changed
after ubuntu updates and reboot.
When I try to open serial port in python I get exception:
'device reports readiness to read but returned no data (device
disconnected or multiple access on port?)'
przem@przem:~/Pulpit/bat/scripts$ python
Python 2.7.6 (default, Jun 22 2015, 17:58:13)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import serial
>>> ser = serial.Serial("/dev/ttyUSB0", 57600)
>>> ser.read()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/serial/serialposix.py", line
475, in read
raise SerialException('device reports readiness to read but returned no
data (device disconnected or multiple access on port?)')
serial.serialutil.SerialException: device reports readiness to read but
returned no data (device disconnected or multiple access on port?)

I know that there are also different users who has this problem.
