You're welcome. > One other thing, is there a sysfs entry that tells me that the gadget > interface is active? You mean "active" as in "powered on and receiving packets", as opposed to "inactive" as in "powered off or suspended and not receiving packets"? No, there isn't any standard sysfs entry for that. It's not clear whether one would rather just know the current state or be notified whenever the state changes. Either way, that information is not exported to userspace. To do it properly would require modifying all the device controller drivers. However if all you care about is g_file_storage then you could add your own sysfs attribute file pretty easily. Or do you mean "active" as in "currently executing a command", as opposed to "inactive" as in "waiting to receive the next command"? That's not available in sysfs either. It would be of limited utility, since commands come and go so quickly. Alan Stern ------------------------------------------------------------------------- Using Tomcat but need to do more?
