FW: USB on MPC8349EMDS
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

Any pointers/help will be appreciated. I know there are some bugs in the Freescale driver that was released as part of their BSP. Are you using a PMC2USB module or just the USB ports on the SYS card? - k

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

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

Low and High speed devices did not work. Yeah, that was due to the bug in the driver if my memory serves me correctly. - k

You'll need something like 2.6.16 plus a patch from Randy Vinson (posted to the list a month or two ago). - kumar
