USBizi: USB Host not working with 1.1 Device

I have a USB 1.1 device I am trying to conenct to USBizi it. It does not enumerate. But 2.0 devices work ok.
I get a DeviceConnectedEvent but when I print the VID and PID it is wrong

static void DeviceConnectedEvent(USBH_Device device)
{
DispPrint(“Device connected…”);
DispPrint("ID: " + device.ID + ", Interface: " + device.INTERFACE_INDEX + ", Type: " + device.TYPE + ", VID: " + device.VENDOR_ID + ", PID: " + device.PRODUCT_ID + ", Port: " + device.PORT_NUMBER);

}
Log:
Device BadConnection…
ID: 0, Interface: 255, Type: 0, VID: 0, PID: 0, Port: 0

Strange as USBizi is 2.0 compatible but runs 1.1

I’d always suggest you try out the USB Discovery Helper to get the full info from devices:

I tried your example
The void DeviceConnectedEvent(USBH_Device device)
does not get called at all then I conenct this device.

Please look at the attached images from the USB sniffer

Is it a USB 2.0 1.0 issue
