Digi NEO adapter is not recognized in Linux

This can be caused by a conflict with the in-kernel jsm driver, where it has claimed the adapter. Check to see if the jsm module is loaded:

# lsmod | grep jsm

If so, unload the module:

# rmmod jsm

The jsm module, should be renamed to prevent it from loading when rebooted:

#cd /lib/modules/`uname -r`/kernel/drivers/serial/jsm

# mv jsm.ko bak.jsm


The system should be rebooted in order for the jsm driver to relinquish control so the dgnc driver can claim the adapter.
