Hi, i'm having a problem with an application of mine that communicates with
a usb-serial device.
It seems that after running a sample application (to send a command 10
times),
if you run the same application again, the application cannot read from
usb-serial. I have
to execute command "stty -F /dev/ttyUSB0" to be able to run the same
application and
read the responses. Maybe something is wrong with how I close the usb-serial
port.
Procedure:
1.) Run application (sending command and reading response 10 times)
2.) What is displayed 10 times
Command sent: size 2
Read: 3
Response: 90 00 AA
3.) Application ends
4.) Run application again
5.) What is displayed
Command sent: size 2
Read: 0
/proc/device, /var/log/syslog, /proc/bus/usb/devices are right below.
I've also included the outputs of dmesg, lsmod and lsusb.
I hope you can help me. And thanks.
Sincerely,
Meema
