Better if you could provide Model. Also if its usb to usb then you can use `lsusb` command to see usb devices on your system.Misam Shah wrote:Dear thanks for the link but I've tried that and works successfully for the ZTE serial to USB cable set whereas PTCL has launched new series of ZTE sets which are USB to USB cable. Hope you will have got the issue correctly now. Please provide if there is any link on new ZTE configuration.
