I have two computers: both running CentOS 6.7, 64-bit, with
kernel 2.6.32-573.12.1.el6.x86_64. One is a laptop with an 2 core Intel
processor and the other is a desktop machine with a 4 core AMD processor. Both
with selinux enabled.
I have a USB serial port device (a RR-CirKits LCC-Buffer USB). On the desktop
I am getting this error:
sauron.deepsoft.com% sudo minicom
Device /dev/ttyACM0 access failed: No such file or directory.
sauron.deepsoft.com% dir -lZ /dev/ttyACM0
crw-rw----. root dialout system_u:object_r:tty_device_t:s0 /dev/ttyACM0
But it is working on the laptop!
gollum.deepsoft.com% dir -lZ /dev/ttyACM1
crw-rw----. root dialout system_u:object_r:tty_device_t:s0 /dev/ttyACM1
Same kernel, same device (except it is showing up as ttyACM1 on the laptop).
What is going on here?
