I've just finished a patch to alleviate several panics in the ugen driver (related to devfs issues and setting a USB device's configuration to USB_UNCONFIG_NO). I'm about to submit to freebsd-current@, but I need to clarify something first.
When setting a USB device to configuration number USB_UNCONFIG_NO (i.e. 0), the device goes into an unconfigured state with an invalid dev->cdesc. How does one then leave this unconfigured state and reconfigure the device to accept configuration changes? (all USB_SET_CONFIG changes are currently refused after going into configuration 0 - I'm not sure if this is the desired behaviour or a bug)
All I can think of is unplugging/plugging the device back in. In which case, why would we want to let users set USB_UNCONFIG_NO in the first place?
