After a couple of seconds of USB data exchange between remsim and cardem, the USB transfer hangs. On host side (remsim) I can see the USB BULK IN request. On device side (cardem) I see that data has been submitted and "sent" over USB, but on wireshark with USBmon I don't see the corresponding USB BULK IN response. When exiting remsim or just after powering of qmod (causing an error in remsim) the USB BULK IN is show in wireshark. Thus it must have been in a buffer, but not read by libusb_bulk_transfer. By shortening the timeout a new libusb_bulk_transfer is made more frequently, and the data gets read successfully. T;his change also fixes the URB data display.

SIMtrace v2.0
This is the repository for the next-generation SIMtrace devices, providing abilities to trace the communication between (U)SIM card and phone, remote (U)SIM card forward, (U)SIM man-in-the-middle, and more.
This is under heavy development, and right now it is not surprising if things still break on a daily basis.
NOTE: Nothing in this repository applies to the SIMtrace v1.x hardware or its associated firmware. SIMtrace v1.x is based on a different CPU / microcontroller architecture and uses a completely different software stack and host software.
Supported Hardware
At this point, the primary development target is still the OWHW + sysmoQMOD device, but we expect to add support for a SAM3 based SIMtrace hardware board soon.
The goal is to support the following devices:
- Osmocom SIMtrace 1.x with SAM3 controller ** this is open hardware and schematics / PCB design is published
- sysmocom sysmoQMOD (with 4 Modems, 4 SIM slots and 2 SAM3) ** this is a proprietary device, publicly available from sysmocom
- sysmocom OWHW (with 2 Modems and 1 SAM3 onboard) ** this is not publicly available hardware, but still supported
This Repository
This repository contains several directory
- firmware - the firmware to run on the actual devices
- hardware - some information related to the hardware
- host - Programs to use on the USB host to interface with the hardware
