Dealing with cdc_acm usb devices
« on: March 06, 2008, 05:41:35 am »
How do I get linuxmce to deal with usb serial devices that register as  ttyACM0 and ttyACM0 instead of ttyUSBx?

The resolution was to ditch the cheap usb serial adapters.  The belkin adapters restore normal functionality.

they should work properly (Seluxit Dongle uses the same generic modem device).
