usb stick problem

I have a problem with my freescale imx28 EVK board. On the usb port I have a 2port hub board connected (EVB-USB2512Q36-BAS_C).

Most of the time I have no problems, but sometimes when I insert a USB-stick I get the following errors:

 

fsl-ehci fsl-ehci.0: port 1 reset error -110

hub 2-0:1.0: hub_port_status failed (err = -32)

fsl-ehci fsl-ehci.0: port 1 reset error -110

hub 2-0:1.0: hub_port_status failed (err = -32)

fsl-ehci fsl-ehci.0: port 1 reset error -110

hub 2-0:1.0: hub_port_status failed (err = -32)

fsl-ehci fsl-ehci.0: port 1 reset error -110

hub 2-0:1.0: hub_port_status failed (err = -32)

fsl-ehci fsl-ehci.0: port 1 reset error -110

hub 2-0:1.0: hub_port_status failed (err = -32)

hub 2-0:1.0: Cannot enable port 1.  Maybe the USB cable is bad?

 

After that error, no usb devices can be added to the hub untill I reboot the imx or reconnect the hub...

 

What could be causing this error? How can it be solved?

Thx
