Hi,

I am working on an FX 3 USB 3,0 device with the firmware developed using the FX3 EZ USB Suite and am seeing some device
registration issues.

The device has a two-phase install. When the device is plugged our driver identifies the device, downloads the device specific
firmware, and triggers a re-enumeration of the device which then comes up using the downloaded firmware and our driver then
hooks it in as a device which sits on top of WinUSB.

The device specific firmware has USB descriptors that should allow it load as either a USB 2.x device running at HS and FS, or
as a USB 3.0 device capable of running at SS, HS, and FS, depending upon which USB slot it is connected to.

Here are the issues that I am seeing:

1. When I plug my device into a USB 3.0 port, it will occasionally register as a USB 3.0 device running at HS, and occasionally as
a USB 2.1 device running at HS. It seems almost random as to which of the two types it will register as.

2. When I attach my device to the USB 3,0 port both usbview.exe and usblyzer.exe takes a long time to run up, or refresh, and list
the devices. This sluggishness does not happen when my device is not connected.

3. When it does register as a USB 3.0 device it does not register as running at SS, but only HS.

4. In neither case do the apps recognize or display the string descriptors I have configured for my device.

When I plug it into a USB 2 port it registers correctly and the strings are seen and displayed by both usbview and usblyzer.

Can anyone offer any suggestions as to why I am seeing these issues?

I have seen on this forum (http://www.cypress.com/forum/usb-30-super-speed/looking-fx3-descriptors-work-winusb) that if the device is to be used with WinUSB you need additional descriptors.

Below are the descriptors for my device (anonymized where necessary).

Thanks,
