I have a CC2530ZNP Zigbee controller connected to a TUSB3410 USB to serial bridge, which is in turn attached to a Linux machine (I've used both CentOS and Raspberry Pi). We were originally having trouble receiving data from the Zigbee network, and I was able to find the solution to our original problem here:

Now I'm experiencing another problem that I'm guessing is related. I can receive data, but I can't seem to send any across the Zigbee network. I'm able to get it working using Windows running a Linux virtual machine (Windows handles the initial USB driver layer and passes it on to the Linux virtual machine as a plain old serial port). However, when I run it directly through Linux, the cdc-acm driver fails me, and it doesn't work. Can anyone suggest a way to resolve this? Is there a newer driver anyone's run across since the topic above was discussed?
