I just finished updating the firmware of my PS3IR-PRO to version 1.11. The process was slowed by a mistake on my part so I thought I would post this in case it saves anyone some time and/or trouble. At first, I was unable to get the PS3IR-PRO to go into Firmware Update Mode until I remembered that I have my Harmony 890 remote configured to control my Playstation 3 using its Wireless Extender. Once I changed my Harmony Remote configuration to control the Playstation 3 using the remote, then pressing the 1 button immediately after connecting the PS3IR-PRO to my computer successfully put it into Firmware Update Mode and I was able to follow the instructions in the "Firmware Update Tool - Files and instructions" post. Hopefully my mistake will save somebody else some time.
