Hello everyone,
I'm having a problem with a Digi Inside Out Networks Edgeport/416
device. According to the kernel.org file (see exerpt below) this
particular model is not listed in the supported products.
The device is connected to a 32 bit CentOS 6.3 machine running with
kernel 2.6.32-279.14.1.el6.i686. When I connect the Edgeport/416, the
messages which show up in /var/log/messages don't show any errors (see
below). The 16 /dev/ttyUSB character devices are created in /dev. I
can see the Edgeport/416 in /proc/bus/devices and in
/sys/bus/usb/drivers/io_edgeport.
But when I try to access any one of the 16 ports, I always get a
timeout followed by a no such device error. If I do this...
sudo strace cat /dev/ttyUSB14
...it always fail with this line :
open("/dev/ttyUSB14", O_RDONLY|O_LARGEFILE) = -1 ENODEV (No such device)
I tried to contact Digi, but their answer is a bit dull :
this driver is supported by the Linux community, we recommend
contacting the Linux-USB group to see if they might be familiar with
this behavior and a possible patch. Otherwise, a bug report should be
filed with them.
I'm not quite sure where to go from there? Any help would be very appreciated.
Many thanks,
David
P.S. Below is the output when I connect the unit to the CentOS machine
and the contents of the
http://www.kernel.org/doc/Documentation/usb/usb-serial.txt file.
