servo_micro_v2: FW update fails

Project Member Reported by sha...@chromium.org, Jun 28 2017 
I'm attempting to update servo_micro_v2 FW.

- EC FW: latest servo branch / a58da6b
- Attached with OTG cable, "ID 0483:df11 STMicroelectronics STM Device in DFU Mode" shows up in lsusb


$ util/flash_ec --board=servo_micro

Any ideas?

you can also use extra/usb_update/fw_update.py (on the branch) or drinkcat@'s usb_updater2 on TOT without the OTG cable.

I've found that for some reason if you plug either USB3 or USB though a monitor hub, STM32 DFU often fails. Can you try a direct plug or a plug through a USB2 hub?

Is this still an issue?
