I'm seeing the following error message when I have a wireless usb ethernet adapter plugged into an embedded PPC SoC. If I plug the adapter in after the SoC has booted the device is detected w/o any issue. Which makes me thing that there is some initialization timing issue.
Any suggestions on what to poke/look/dbg at would be helpful. thanks - k [ 7.193084] ehci_hcd: block sizes: qh 128 qtd 96 itd 192 sitd 96 [ 7.193280] initializing FSL-SOC USB Controller [ 7.193312] fsl-ehci fsl-ehci.0: Freescale On-Chip EHCI Host Controller [ 7.193644] drivers/usb/core/inode.c: creating file 'devices' [ 7.193675] drivers/usb/core/inode.c: creating file '001' [ 7.193696] fsl-ehci fsl-ehci.0: new USB bus registered, assigned bus number 1 [ 7.193731] fsl-ehci fsl-ehci.0: reset hcs_params 0x10011 dbg=0 ind cc=0 pcc=0 ordered ports=1 [ 7.193753] fsl-ehci fsl-ehci.0: reset hcc_params 0006 thresh 0 uframes 256/512/1024 park [ 7.193898] fsl-ehci fsl-ehci.0: park 0 [ 7.193920] fsl-ehci fsl-ehci.0: reset command 080b02 park=3 ithresh=8 period=1024 Reset HALT [ 7.193943] fsl-ehci fsl-ehci.0: ...powerdown ports...
