Yeah, that was due to the bug in the driver if my memory serves me correctly. - k

Are you using a PMC2USB module or just the USB ports on the SYS card? - k

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
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
