Why Fx3 Device was switch to EHCI Mode When it Connected to XHCI Mode?
a FX3 Device Connected to a XHCI Host controller， the most time it works fine in XHCI Mode， But some time， when i install the driver for the device； or Hot-Plugging the device and so on， the FX3 device is changed to USB2 Device(the usbdevice in device descriptor is 0x210).
But,we don't want our fx3 device using in EHCI mode, is there any help？
thanks in advance
Have you tried by changing the USB cable ? It seems to be a host specific error. how may XHCI PCs have you tested? FX3 can work as a USB 3.0 device, but in host mode it can only work as USB2.0 I would recommend you to gather more test data, the steps to follow if the issue is consistent and create a technical support case for further assistance
