Other Parts Discussed in Thread: CC2531, Z-STACK, CC2531EMK
I am attempting to run the Z-Stack Linux Gateway sample on a BeagleBone Black with a CC2531 USB dongle. I have tried several versions of Linux distributions:
- eLinux latest (Angstrom) for BeagleBone (http://elinux.org/Beagleboard:Updating_The_Software#Image_For_Booting_From_microSD)
- latest Debian (8.5) from beagleboard (https://beagleboard.org/latest-images)
- Debian 7.8 from beagleboard as recommended by https://e2e.ti.com/support/wireless_connectivity/zigbee_6lowpan_802-15-4_mac/f/158/t/511206
In all cases, cdc-acm driver does not get connected to device when plugged in. dmesg output:
[ 1.128093] usb 1-1: new full-speed USB device number 2 using musb-hdrc

I expected to see messages that the cdc-acm driver was used to create the /dev/ttyACM0 device, but I am not finding anything.
If I go ahead and run the script to start the server, it fails to find the /dev/ttyACM0 device on the first attempt and eventually retries. On the second attempt, the /dev/ttyACM0 device is there, but does not seem to be responding:

^Ccaught SIGTERM, killing all the servers and cleaning up
The process hangs at that point until I kill it.
It appears that the /dev/ttyACM0 being created is not really a device, but just a file:
root@beaglebone:~/z-stack_GW/servers# stty < /dev/ttyACM0
stty: standard input: Inappropriate ioctl for device
root@beaglebone:~/z-stack_GW/servers# ls -l /dev/ttyACM0
-rw-r--r-- 1 root root 33 Nov 4 12:33 /dev/ttyACM0
root@beaglebone:~/z-stack_GW/servers# file /dev/ttyACM0
/dev/ttyACM0: data
I have no idea what in the process might be creating this file.
If I attempt to inform the cdc-acm driver that this USB device should be handled by it, the probe does not get valid info back:
~/z-stack_GW/servers# echo "0x0451 0x16ae" > /sys/bus/usb/drivers/cdc_acm/new_id
[ 1802.256030] cdc_acm 1-1:1.0: usb_probe_interface

I also tried loading the CC2531-GW-ZNP_38724.hex firmware file that comes with the Linux Gateway package, thinking perhaps the chip was not initialized properly, but the serial bootloader also uses the /dev/ttyACM0 device...
root@beaglebone:~/z-stack_GW/tools# ./sbl_tool.bin CC2531-GW-ZNP_38724.hex USB

Resetting USB connection. It takes a few seconds...
/dev/ttyACM0: No such file or directory
/dev/ttyACM0 open failed
/dev/ttyACM0: No such file or directory

Any ideas on why I might be seeing this problem with the serial connection?
I am not 100% certain that it is related to the CC2531 USB stick, but my wired ethernet connection is dropping off also.
Thanks!
