Re: UMTS Device - T Mobile Web And Walk



Hi,


no there was no device node created named like /dev/hso0, but the sysfs interface was created.

Inside the sysfs path i don't see the "file" "dev", which should contain the device node information. So udev has no idea how to create this device node.

Dan: What does ls -l /dev/hso0 show for your device?
