It was the hardcoded default in versions +< 0.100. + +This incompatibility is needed so connecting software is able to +differentiate between HM-CFG-LAN and HM-CFG-USB. + +**Important security information:** +Versions before 0.101 do not correctly transmit the AES channel-mask +to the HM-CFG-USB, which results in signature-requests not being generated +by the device in most cases. This can lead to processing of unsigned messages +by the host-software. If you are relying on authenticated messages +(with e.g. aesCommReq in Fhem) from devices like door-sensors and remotes, +you should upgrade to at least version 0.101. + +[releases-directory]: https://git.zerfleddert.de/hmcfgusb/releases/ +[hmcfgusb-HEAD-xxxxxxx.tar.gz]: https://git.zerfleddert.de/cgi-bin/gitweb.cgi/hmcfgusb/snapshot/HEAD.tar.gz +[Homegear]: https://www.homegear.eu/ + ### Updating the HM-CFG-USB firmware to version 0.967: ### -1.
