u-link Posted March 22, 2017 Report Share Posted March 22, 2017 I recently upgraded to a STM32F4 Core. Everything works fine, except that I cannot power the sequencer from a USB hub (via either USB connection). The backlights of the screens turn on, but it doesn't boot. Anybody knows what I am doing wrong? Thanks a lot for input. That came as a surprise when I used the sequencer (for the first time ever) for a live PA recently. I had to ask a friend to go fetch a laptop, otherwise it wouldn't have worked. Quote Link to comment Share on other sites More sharing options...

FantomXR Posted March 22, 2017 Report Share Posted March 22, 2017 latigid on is right: you need to update the STM-firmware to the latest version. Thorsten mention it here: http://ucapps.de/mbhp_core_stm32f4.html "Required Firmware Update" Quote Link to comment Share on other sites More sharing options...

u-link Posted March 27, 2017 Author Report Share Posted March 27, 2017 That did the trick, now it boots from either USB port connected to a hub. Thanks again for the pointer sisters. Quote Link to comment Share on other sites More sharing options...
