Hello Greg,
Thanks for the suggestion. See my comments below.

I totally agree here.

Everytime I try this with kernel 3.7.0-1.el6.elrepo.i686 I always get
this error :
FATAL: Error inserting io_edgeport
(/lib/modules/3.7.0-1.el6.elrepo.i686/kernel/drivers/usb/serial/io_edgeport.ko):
Invalid argument
I've tried different syntaxes, but it always fails.
Meanwhile, I power cycled the Edgeport/416 device and now kernel
3.7.0-1.el6.elrepo.i686 can see all 16 ports. But I still can't access
any of the /dev/ttyUSB* devices.
So I installed kernel 2.6.32-279.14.1.el6.i686 from the base CentOS
repository and this time the sudo modprobe io_edgeport debug=1 command
worked (i.e. I was able to load the kernel module without the invalid
argument error). This kernel has io_edgeport module version 2.7.

I'm still on kernel and I still get this error :
open("/dev/ttyUSB0", O_RDONLY|O_LARGEFILE) = -1 ENODEV (No such device)
I tried both module sides (i.e. ttyUSB0 and ttyUSB10) as this unit is
basically two 8 port switches bundled together. Both sides fail with
the ENODEV error.

Indeed.
I'm no expert of kernel modules, but what I see and I don't understand
is those lines...
drivers/usb/serial/io_edgeport.c: downloading firmware version (930) 1.16.4
...then...
drivers/usb/serial/io_edgeport.c: Current Boot Image version 1.13.7
drivers/usb/serial/io_edgeport.c: Boot Image -- already up to date
...but didn't it download version 1.16.4 and now it's saying that
1.13.7 is up to date? Unless these are different firmware for
different parts of the unit.
Also, the driver seems to be hitting a timeout when it tries to open a
port. This error shows up for both /dev/ttyUSB0 and /dev/ttyUSB10 :
drivers/usb/serial/io_edgeport.c: edge_open - open timedout
Maybe we can increase the timeout value in the driver? Again, I'm no
expert, just trying to help :)
