Hi,

I have linux kernel (2.6.11) from Freescale running on the MPC8349EMDS.
I am using the BSP from Freescale which is supposed to have USB support.

However, I seem to be having problems with USB host support.

When I insert a USB Mass storage device (thumb drive), I get the
following errors

/ #  usb 1-2: new high speed USB device using fsl-usb2-mph and address 8
usb 1-2: khubd timed out on ep0in
usb 1-2: new high speed USB device using fsl-usb2-mph and address 9
usb 1-2: khubd timed out on ep0in

It does not show up in /proc/bus/usb/devices (I do have usbfs mounted).

I also have usb-utils installed and lsusb fails to list the device.

I have also tried other USB devices and get similar errors.

Has anybody else experience similar problems? Any pointers/help will be
appreciated.

Thanks,
Prashant

I am connecting to the USB port on the board using the USB adaptor. I
tried both configurations (MPH and DR).

I also tried the latest stable kernel (2.6.16.12) but that doesn't
compile for this board. Is there a later (later than 2.16.11) kernel out
there which works for this particular board?

Another possibility might be that the eval board I have is bad. I can't
seem to get my hands on the errata.

Also waiting to hear back from Freescale folks.

Prashant

When I used that driver I found it only worked with Full speed devices.
Low and High speed devices did not work.
