I don't know exactly which request field this is, but: USB requests are always sent to or received from an endpoint. All USB devices have at least two endpoints, 0 IN and 0 OUT. They are always control endpoints. lsusb and /proc/bus/usb/devices seems to just omit them, probably since they're always present. //Peter _______________________________________________ opensc-devel mailing list opensc-devel@lists.opensc-project.org http://www.opensc-project.org/mailman/listinfo/opensc-devel
