I had several issues installing firmware on my Thrustmaster Warthog HOTAS. The throttle would not finish installation and gave me "bulk write errors".
Steps to fix this problem:
Step 1: Uninstall Thrustmaster Target
Step 2: Uninstall Thrustmaster Warthog drivers
Step 3: Shutdown computer
Step 4: Unplug Thrustmaster Warthog from computer
Step 5: Turn on computer
Step 6: Install Thrustmaster Warthog drivers. During the installation it will ask you to plug in the Warthog Hotas to proceed
Step 7: Run Firmware updater in Thrustmaster Warthog start menu folder
Step 8: Install Thrustmaster Target
No more issues with the Warthog Hotas!

You will not be disappointed with its precise controls and heavy weighted joystick that matches exactly what is in the A-10C.
