I have the same problem here. I can't connect a keyboard on an usb hub connected to STM32F429I-DISC1 ... The library seams to not work properly.

@jeremydufour We are waiting on ST to take a look.

No idea why it does not work on the NUCLEO_F429ZI, we'll have to look at it.

But concerning the support of USBHost on the DISCO_F429ZI is has not been enabled due to unresolved issue (see PR #5617). No progress since that time on this board.

I have the same problem with the NUCLEO-F446RE board.
Each time I connect a USB device to the board, I get 10 USB_ERRs and one USB_INFO with address of 0x2000549c.

@bcostm I added support for DISCO-F429ZI. My commit is here 859c607

I need your approval before opening a pull request

@jeremydufour So, I checked your commit and it is almost the same as I did (and removed) in my commit c621c68. Only difference is that in your case you didn't configured the VBUS pin.

Anyway it didn't work for me. I test it using the features\unsupported\tests\usb\host\mouse test.

Can you tell me the board name/version you have ? The state of the solder bridges SB18, SB19 and SB20. And finally can you test the USB Mouse test code ? Thanks.

@bcostm Sorry for the late reply. I have a STM32F429I-DISC1 board. I can't test the solder bridges right now but I keep you updated for the next two weeks. I will try soon the USB Mouse test code as well.
