Description

With the current 2.6.28 kernel the device can switch between device and host mode using the sysfs files: 

/sys/devices/platform/s3c2410-ohci/usb_mode
/sys/class/i2c-adapter/i2c-0/0-0073/neo1973-pm-host.0/hostmode

A DBus interface would be very handy. Maybe the interface also unloads unused modules. Furthermore, unpowered and powered host mode should be selectable.

Probably more some method that allows us to switch to host mode or one of the different gadget modes (cdc_ether, storage, ..)

Please take into account that from 901d73fe51f33032b34b2ae5612eb863ec90532a (Wed Apr 8) the path was changed to 

/sys/devices/platform/s3c-ohci/usb_mode

  • Priority changed from major to minor
  • Summary changed from Interface to toggle USB between host and device mode to Interface to toggle USB host between powered and unpowered modes

The interface was implemented long time ago, a patch to be compatible with modern kernels committed.

Still it'd be nice to have a switch between powered and unpowered usb host modes.
