I don't know if it will help you but I'm using USB host mode and I didn't have to start a module or to change the kernel configuration. Only the patch was enough. Then to switch to host I did: > ifconfig usb0 down (to prevent crash of the usb networking) > echo "host" > /sys/devices/platform/s3c2410-ohci/usb_mode
So I can't see why you wouldn't have the /sys/devices/platform/s3c2410-ohci/usb_mode file. Strange... I think USB host is already included in kernel 2.6.24 so it could be an alternative for you. -- Jean-Michel Bouffard Felipe Balbi wrote: > > On Fri, 7 Mar 2008 18:08:13 +0530, "Phani Kumar Kancharala" > <[EMAIL PROTECTED]> wrote: >> yeah, Driver -> USB -> Gadget -> Ethernet Gadget Drive is already > enabled. >> In fact, I could able to use Ethernet over USB. >> FYI, >> I am using 2.6.22.5 kernel patched with the usb_mode_swith.patch >> I cross verified whether the patch is applied correctly using the tool >> "nm", it listed both show_usb_mode and set_usb_mode on the ohci_hcd.ko. > > Hmm, so you should have the sysfs entry. > > find /sys -name mode should help you find it ;-) > >> Thanks n Regards, >> Phani Kumar >> >> On Fri, Mar 7, 2008 at 5:51 PM, Felipe Balbi <[EMAIL PROTECTED]> wrote: >> >>> >>> On Fri, 7 Mar 2008 17:30:44 +0530, "Phani Kumar Kancharala" >>> <[EMAIL PROTECTED]> wrote: >>>> Thanks Felipe, >>>> The module ohci-hcd is loaded but use count is zero. >>>> what do you mean by gadget driver? where can I get it?? >>> make menuconfig >>> Driver -> USB -> Gadget -> Ethernet Gadget Driver ;-) >>> >>> enable that one ;-) >>> >>> BTW, HCDs will always have usecount 0, this is done so you can >>> rmmod/modprobe easier. >>> good for debugging :-p >>> >>>> Best Regards, >>>> Phani Kumar >>>> On Fri, Mar 7, 2008 at 4:59 PM, Felipe Balbi <[EMAIL PROTECTED]> >> wrote: >>>>> >>>>> On Fri, 7 Mar 2008 15:35:10 +0530, "Phani Kumar Kancharala" >>>>> <[EMAIL PROTECTED]> wrote: >>>>>> Hi all, >>>>>> I am trying to run the usb in host mode.
