Dear osmocom team,
I am trying to set up the osmocom-remsim application. The goal is, that
the phone uses the SIM inserted into the card reader and connects to my
EPS. I am using a SCR 3310 Card Reader and the simtrace2 hardware. I
setup the bankd and the slotmap according to the manual. It seems, that
the mapping is fine although, when I start the client, the execution
terminates with "USB OUT transfer failed, status=2". The phone does not
recognize a SIM inserted.
Setup:
Debian 11, simtrace plugged into the computer. Simtrace is attached to
a mobile Phone (Samsung galaxy A90 5G or Apple iPhone 13). SCR 3310 has
a sysmoISIM-SJA2 card inserted, which is configured to attach to a
custom cell distributed via srsRAN.
Note that the OS is hosted as a VM with KVM/QEMU. When using only the
simtrace, without remism, the SIM Card which is inserted into the board
works as intended and the phone connects with my EPS.
Configuration:
bankd_pcsc_slots.csv:
"1", "0", "SCM Microsystems Inc\. SCR 3310 \[CCID Interface\]
\(53311702704887\) 00 00"
