Hi, I'm having an extremely frustrating situation trying to deal with the aforementioned gaming mouse. Every 4-5 weeks, it decides to go dead - all the mouse buttons work, but the tracking of the cursor does not work. I've tried turning it off/on when it's plugged in multiple times, and I try cold booting it and then pairing it immediately when it's not plugged. Neither works, it's been almost 3 days, I'm starting to twitch. Here are my MB's specifications: Model: Summer 2008 Macbook CPU: Intel Core 2 Duo 2.4GHz ---- When the Charging Dock is plugged in that enables wireless: USB Bus> Product ID: 0x000f Vendor ID: 0x1532 Version: 0.01 Speed: Up to 12 Mb/sec Manufacturer: Razer Location ID: 0x1d100000 Current Available (mA): 500 Current Required (mA): 100 ---- When the actual Razer Mamba is plugged in: USB Bus> Product ID: 0x000a Vendor ID: 0x1532 Version: 2.00 Speed: Up to 12 Mb/sec Manufacturer: Razer Location ID: 0x1d100000 Current Available (mA): 500 Current Required (mA): 100 ---- My OS X I'm running in v10.5.8 (I know it isn't the newest version, but I don't see any reason on dumping 30$ on a minor hardware upgrade unless it helps out my gaming).
