I agree. That's why people are still working on the power management system :) > The devices are simply assumed to switch from suspended to working > in kernel space. Suspended may mean off here. If "suspended" means off, then the device should start up in the powered off state, and re-enumerate as a new usb device on powerup. If you _have_ to handle this today, then just leave the firmware within the kernel driver, like all of the usb-serial devices have done :) If you wait a while, the rest of the power management sections of the kernel will hopefully come together, allowing the various states of shutdown to work properly, and be enumerated by _userspace_ tools. That's the whole driving force behind driverfs, which I think people forget. thanks, greg k-h _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
