Hello! 
I have a Samsung SCH-S379, but I do not have a UIM/SIM card for it yet. When I try to connect to my Windows XP PC with New PC Studio (NPS), it sees that there is a device connected but it says 'Identifying the device failed. Move to search new device.' I have tried reinstalling NPS and the USB drivers from the samsungcdma website and the samsung India site. They all have the same problem. 
Do I have to have a UIM/SIM card in the samsung sch-s379 for NPS to work?  
If someone has a samsung sch-s379 and uses NPS can you try removing your UIM/SIM card and testing to see if NPS works with your phone without the UIM/SIM card in it? 
Thank you!
