p The options are as follows: l -tag -width " " t Fl u Ar unit Limit device range to USB devices connected to the given USBUS unit. t Fl a Ar addr Limit device range to the given USB device index. Should only be used in conjunction with the unit argument. t Fl d Ar [ugen]<unit>.<addr> Limit device range to USB devices connected to the given unit and address. The unit and address coordinates may be prefixed by the lowercased word "ugen". t Fl h Show help and available commands. .El
p When called without options, .Nm prints a list of all available USB devices. .Sh EXAMPLES Show information about the device on USB bus 1 at address 2:
p .Dl usbconfig -u 1 -a 2 dump_info
