28069 USB Device Problem...

Other Parts Discussed in Thread: CONTROLSUITE

The MCU is currently in use 28069.
I am using a usb BULK communication.

I was using the Example of usb_dev_bulk Source ControlSuite.

WIndows PC was connected to the USB Port of the USB cable.

In the Device Manager Control Panel, you will see the device as a "Generic Bulk Device".

However, it is connected to the "USB Universal Host Controller" this device.

The "USB Universal Host Controller" is USB 1.x mode.


I found that strange.

When the hub is connected to the 28 069 to support USB 2.0.

Now is the connection to the "USB Enhanced Host Controller" this device.

The difference between the communication speed of the two.

When the connection to the "USB Enhanced Host Controller" faster speed.

I noticed the difference more than twice the speed difference when the speed measurement.

The "USB Enhanced Host Controller" is the USB 2.0 mode.

Without being connected to the hub, there is to be connected to the "USB Enhanced Host Controller"?
