Hi there,
I have built and installed the requirements for OpenBTS and my USRP (Ettus 
N210) is responding but now I am stuck at SIM card stage. I am trying to 
program a Super SIM 16-in-1 using the 
Insten_USB_SIM_Card_Writer<https://www.amazon.com/Insten-Reader-Writer-Backup-Phone/dp/B0188GHIP2/ref=pd_sbs_147_1?_encoding=UTF8&pd_rd_i=B0188GHIP2&pd_rd_r=7814918c-6ce3-11e8-8c85-6f6601b90f74&pd_rd_w=uWdRH&pd_rd_wg=JuNOy&pf_rd_i=desktop-dp-sims&pf_rd_m=ATVPDKIKX0DER&pf_rd_p=5825442648805390339&pf_rd_r=KR5JHK6G2A4ATF92VJ6S&pf_rd_s=desktop-dp-sims&pf_rd_t=40701&psc=1&refRID=KR5JHK6G2A4ATF92VJ6S>
 and following the steps mentioned 
here<http://openbts.org/w/index.php?title=ProgrammingSIMcards> and 
here<http://osmocom.org/projects/pysim/wiki> but unable to write the sim card.  
Every time I run the pcsc_scan command it stops working. Below is the output.

"wslopenbts@wslopenbts-desktop:~$ pcsc_scan
PC/SC device scanner
V 1.4.25 (c) 2001-2011, Ludovic Rousseau <[email protected]>
Compiled with PC/SC lite version: 1.8.14
Using reader plug'n play mechanism
Scanning present readers...
Waiting for the first reader...^C"

The problem seems that the PC is not getting the SIM card reader. But the SIM 
card reader was plugged into the PC while running the command and the LED 
turned red which indicate it was getting the power from the PC. Do you think, 
buying another new SIM card reader can resolve the issue? I can test by buying 
another SIM and SIM card reader; Do any of you have any suggestion for the SIM 
and SIM card reader, particularly which one will be good? Finally, any 
guideline for me regarding programming the SIM card. I will be very grateful if 
you help me by giving suggestions to resolve my issue.

Can anyone please help me regarding this issue.

Thanks in advance
Best Regards,
Farah
