Hello, Dual USB works on dipCoreF4 ;) ... Is it possible that in Host mode, the USB requests more processes in IDLE state than in RX state? Has anyone noticed that? When I plug a PadKontrol and I do not touch it the screen is slowed down... but if I turn a knob or hit some pads continuously the screen refreshes normally. I think this is related to the fact that the transmission is in BULK because with a keyboard or a mouse(HID class), which use the interrupts, no problem. Someone? Best regards Bruno

I made a short video for dipCoreF4 new second USB Host port. I made a dirty MIDI class which will deserve to be cleaned and integrated better in MIOS32 but it works. I tried to use the OTG_HS dedicated DMA but it's maybe a bit complicated for me, I will need help for that part. (edit) maybe DMA don't work with BULK transfer type !? So here first regular USB(OTG_FS) is connected to my laptop and MIOS Studio. Then I'm connecting 2 different MIDI devices to the second USB(OTG_HS in FS and Host mode), a waldorf streichfett and a Korg PadKontrol. Then I try Mouse and Keyboard for HID demonstration. Hope you like this new feature cause USB is a tricky thing to code!
