Sim Card Reader Driver: A Solution for Linux Users

If you're a Linux user looking to read and edit SIM cards using your device, you're in luck. The scsisim library is here to help. This user-space 'driver' provides an API for accessing USB SIM card readers that use the SCSI protocol.

To get started, simply run `lsscsi -g` if you have the lsscsi program installed. Alternatively, you can use the demo application with command-line options. For example, you can determine the SCSI generic name for a device by running `dmesg | grep 'scsi generic sg'`, and then use the demo application with that name.

The scsisim library was developed to solve a problem faced by Linux users who own USB SIM card readers that use the SCSI protocol. One such reader is the APM UR-200, which I purchased in France. While there are many serial-based and PC/SC-based USB SIM card readers available, support for them on Linux is generally not an issue.

However, until now, Linux users have been left out of luck when it comes to reading and editing SIM cards using their devices. That's where the scsisim library comes in. By reverse-engineering the device's initialization packets and SIM commands, the library provides a way to read from and write to the SIM card using standard GSM commands embedded in SCSI commands.

The library includes a demo application that you can use to test it out. Simply run `demo sg3 -p 1234`, where `sg3` is the SCSI generic name of your device (for example, if you're using an Orange France SIM card) and `1234` is the PIN number you want to send.

The scsisim library is a user-space 'driver' that calls into the Linux SCSI generic kernel driver. It's designed to be easy to use and provides a simple API for accessing USB SIM card readers that use the SCSI protocol.

If you're interested in contributing to the project, pull requests are welcome. With your help, we can make the scsisim library even more powerful and useful for Linux users everywhere.

The scsisim library is a game-changer for Linux users who own USB SIM card readers that use the SCSI protocol. By providing an API for accessing these devices, it makes it possible to read and edit SIM cards using your device, as well as view and edit additional 'hidden' SIM files and data that Windows applications may not support.

Whether you're a developer looking to create your own application or simply a user who wants to get more out of their device, the scsisim library is definitely worth checking out. With its ease of use and powerful API, it's an essential tool for anyone who needs to work with SIM cards on Linux.
