Razer Mamba Problem

Unfortunately a firmware update for Razer products is actually flashing the ROM on the mouse itself. So essentially you may have wiped all of the settings on the hardware itself and now it can't tell your PC "hello I'm a Razer Maba firmware version xxx...".

The only thing to try would be to try updating the firmware on a different PC. If you're lucky and it gets detected, upgrade the firmware and try load the drivers on your PC. If it's unresponsive on another PC, you'll have to contact Razer.

I had this same issue when the software hung. I thought my mouse was dead(no lights, no response when plugged in on my Vista machine). The way I solved it was to goto my XP machine(this may work in Vista 32bit too but I have 64bit and didn't wanna chance it) and install the firmware update software.

After installing the software, run it and get to the screen that tells you to hold down the pairing button when connecting the mouse. Then make SURE your mouse is turned OFF via the ON/OFF switch on the bottom, then HOLD the pairing button on the bottom of the mouse and connect the USB cable. When you do this, you should see a note that XP sees a bootloader and it will want to install a driver for it. Let XP install automatically. When it is done installing the driver, click next on the software screen and it should say it sees the mouse and the UPDATE button should be green. Click it and it will update. This should work, even if it looks like your mouse is dead(no lights when plugged in and not being recognized properly).

The key parts are make sure the mouse is OFF(vai the switch on the bottom) before starting and also make sure you hold the pairing button down when connecting the USB cable. If your system doesn't see a bootloader when you connect the mouse, the update won't work properly.

Here is the solution
