A growing thread on the official PlayStation 3 forum alleges the recent hardware firmware upgrade to version 3.00 has spawned a host of controller connection issues for PS3 users. According to the forum, various wireless controllers -- some users specifically naming DualShock3 model CECHZC2H (Ceramic White) -- are unable to connect to the console. When turned on, users claim the controller LEDs for ports 1 and 2 activate, but the controller remains inoperable.

Users attempting to troubleshoot the problem claim that resetting the controller (through the built-in pinhole reset function) and plugging it directly into the console (via USB) do not correct the error, with one user going so far as doing a complete system restore to no avail. The issue, however, appears to be isolated, but is still a concern for a number of gamers.

Update: Overnight, the issue has spawned an interesting development. Users are pointing out that the problem may be isolated to "knock-off" PS3 controllers. Joystiq has contacted Sony for an update to see if XMB 3.00 targets these fakes or if the controller issue is simply a byproduct of the controllers not being able to catch up with the new firmware.
