No response from board

Just recieved pixhawk device. I’ve connected safety switch and buzzer and now trying to upload firmware.
Installed MP. The drivers looks like installed successfully: the Pixhawk is in the Devices list with “Working” status.

In the MP going to Initial setup, choosing Quad configuration and COM3 port.
Trying to upload firmware. Looks like MP downloads the firmware, and it asks me to replug device and hit OK. After that I’m reciving message - No response from board.

LED Status:
FMU PWR - constant green
FMU B/E - not glowing
IO PWR - constant green
IO B/E - constant orange
IO ACT - flashing blue
SafetySwitch - flashes red

When Pixhawk is connected normal sound is buzzering (accoring to manual).

I’ve also tried to run px4uploader manually, but constant message “xxx not there…” is displayed.

Same issue here. Any resolution?

Try using a powered USB Hub.
