+# coolscan-updater
+
+This is a minimal updater program for use with USB-based Coolscans.
+It is based on a LS-40 USB traffic dump kindly provided by Gleb Shtengel.
+Not all traffic is replicated perfectly - just enough to install the update.
+SCSI (native or over Firewire) is not supported but shouldn't be too hard to add.
+
+To build, use CLion - or CMake with a MinGW toolchain if you're an expert.
+
+There are no user-friendly files here - instead, look in the Releases section
+of this repository for a user-friendly package.
