Hello,
Recently I acquired a SIMtrace2 card unit with ATSAM3S in order to build a P.O.C. of the communication of the SIM card and the modem remotely, but I could not make the application to communicate via USB with the SIMtrace2.

I followed this steps (all of them) https://osmocom.org/projects/simtrace2/wiki/Cardem

After I run this command:
osmo-remsim-client-st2 --usb-vendor 1d50 --usb-product 60e3 --usb-path 1-2.2 --usb-config 1 --client-id 1 --client-slot 1 --server-ip 127.0.0.1 --server-port 9998 -d DMAIN,1:DST2,1:DRSPRO,1

I'm stuck in this error (even running as sudo):
DMAIN DEBUG fsm.c:456 CLIENT_MAIN(main){INIT}: Allocated
DRSPRO DEBUG fsm.c:456 RSPRO_CLIENT(server){INIT}: Allocated
DRSPRO DEBUG fsm.c:456 RSPRO_CLIENT(server){INIT}: Allocated
DRSPRO DEBUG remsim_client_main.c:185 RSPRO_CLIENT(server){INIT}: Received Event SRVC_E_ESTABLISH
DRSPRO DEBUG ../rspro_client_fsm.c:355 RSPRO_CLIENT(server){INIT}: state_chg to REESTABLISH
DRSPRO INFO ../rspro_client_fsm.c:308 RSPRO_CLIENT(server){REESTABLISH}: Creating TCP connection to server at localhost:9998
DMAIN ERROR user_simtrace2.c:430 can't open USB device

Additional information:
- Host S.O.: Debian 10 armhf. Also tried on Ubuntu 22 x64
- I've tried to recompile software following `Get and compile the software`, but these steps really doesn't work.  Then I tried aclocal, autoconf, automake --add-missing & ./configure but nothing of them can rid of the error: cannot find input file: `include/Makefile.in'
- SIMtrace2 firmware: $ sudo simtrace2-list
  USB matches: 2

Sorry if this issue was addressed in another email, I even tried looking in the archives but the archives page is not very user friendly.

Thanks for your support, Bruno Natali
