2nd USB Host controller

NETMF & Gadgeteer
1

The USB host on Pins 182 & 184 is working. And the file download through the Ethernet from the USB drive on this port is 2.08Mb/s… Nice

It is the other USBh port that is on Pin 188&190 that is not working…

I connected a Ellisys USB analyzer and see that the descriptors are read. But I do not get any events

If I pause and run it again I get
30:39:St:USB MS Detected
30:53:St:USB MS Detected

Do you have the development system so you can test the module on it?

I am pretty sure this is working fine on the development system.

I loaded the latest SDK 4.1

Now the 2nd USB Host works.

The first drive enumerates as USB
second as USB0

Thanks
