Quanton is the only F4 board with VBUS connected to the correct pin (PA9) for hardware (USB peripheral) VBUS detection and also the only one that doesn't suffer this bug....

Didn't have Brain/Re1 schematics but looking at the hardware defs they should be both PA9 too? They are configured as no pull though. I assume they have external pull-downs?

Can't repro success with Quanton now... :-1: When it's in the state where board isn't responding... Wireshark shows me that the USB descriptors can still be read, but the HID...

Stopped at a random time while in the bad state: EP1 == HID OTG_FS_DOEPCTL1, EP1 control register (0x50000B20) = 0x800e8040, or: 31: EPENA: Endpoint enable: 1 30: EPDIS: Endpoint disable:...

This is a dup. of TauLabs/TauLabs#1663. Not a blocker for this release.

Definitely at least two different bugs. In some cases, DCD_HandleInEP_ISR fires continuously (looks like Tx FIFO empty on endpoint 1), this one would cause a watchdog reboot if I didn't...

I'm ok with that tbh, I want my motor(s) to stop when I'm not in control. :/

Good call. :+1:

It really is just Q __Gamepad__. Cannot get half the axes and buttons of my joystick out through it even through the undocumented parts of the API so it wasn't...

Played with this some more, with the Qt 5.9 docs (https://doc-snapshots.qt.io/qt5-5.9/qtgamepad-index.html) and reading the source code (https://github.com/qt/qtgamepad/tree/dev/src). I _can_ get all the axes on my joystick to work with the...
