Hi Anders,

Thanks for reworking the series, I was able to get DFU boot to work properly
and the usb devices are being discovered properly too.

Though I ran into an issue while using ums with your patches as the host isn't
able to detect the connected device. With default logs I only see a
'\dwc3-generic-peripheral usb@31000000: unknown endpoint event 0'.

Further debug logs are below on TI's AM62p EVM:

I observed a similar issue on the beagleplay too. Regards!
