Hello Alan, Thank you for the suggestion. > Please try a recent upstream kernel. 2.6.32 is old, and the Red > Hat/CentOS version quite a bit different. If 3.6/3.7 break then yes we > might care about it. I've tried with kernel 3.7.0-1.el6.elrepo.i686 from http://elrepo.org/tiki/kernel-ml but unfortunately it's even worse. Now the OS only sees half of the Edgeport/416. Ports 1 to 8 are seen and /dev/ttyUSB0 to 7 are created. But I still can't access them. Ports 10 to 16 are not seen and the character devices are not created. Performing `sudo strace cat /dev/ttyUSB0` results in this error : open("/dev/ttyUSB0", O_RDONLY|O_LARGEFILE) = -1 ENODEV (No such device) Which is exactly the same error I used to get with kernel 2.6.32-279.14.1.el6.i686. But at least with that kernel version, the OS would see the full 16 ports of the Edgeport/416. This Edgeport/416 hardware successfully passed the Digi digital loopback test as explained in this article http://www.digi.com/support/kbase/kbaseresultdetl?id=3061. The test was performed on a Windows 7 machine. The model's PN is (1P) 50000780-01 E. This device appears to be faulty according this Digi forum thread : http://forums.digi.com/support/forum/viewthread_thread,4977#15792 Any help would be appreciated. Many thanks, David P.S.
