Dear List,
I have read through more Linux kernel docs,
HOWTOs, and online pages than I can shake
a memory stick at (including this list archive)
and have _not_ been able to solve this one,
so I am asking you for your kind assistance.
I have a Linux 2.4.18 kernel on a PPC platform.
Everything I have done so far has been very
straightforward. I have now been attempting
to add USB support. I can get the root hub
on this MPC5200 PPC chip to recognize that
there is something out there, but cannot
convince it to connect to it and so show it
to the world as a disk through the SCSI
interface. It always comes back as error 110,
which is ETIMEDOUT. If I get this connection
made will the device show up? Will the SCSI
driver be properly loaded? All comments are
appreciated.
Thanks,
Dan
I configured the kernel with all
static USB and SCSI code so there
are no modules, just static linkages.
For USB:
CONFIG_USB=y
CONFIG_USB_DEBUG=y
CONFIG_USB_DEVICSFS=y
CONFIG_USB_OHCI=y
CONFIG_USB_PPC_5xxx=y
CONFIG_USB_STORAGE=y
CONFIG_USB_STORAGE_DEBUG=y
For SCSI:
CONFIG_SCSI=y
CONFIG_BLK_DEV_SD=y
CONFIG_SD_EXTRADEVS=40
CONFIG_SCSI_CONSTANTS=y
CONFIG_SCSI_LOGGING=y
Here is the console output:
