Nice, I would just remove the extra empty lines. Linux' "lsusb -t" for example produces this: holger@desktop:~$ lsusb -t /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M |__ Port 1: Dev 2, If 0, Class=hub, Driver=hub/8p, 480M |__ Port 1: Dev 27, If 0, Class=HID, Driver=usbhid, 1.5M |__ Port 2: Dev 4, If 0, Class=HID, Driver=usbhid, 1.5M |__ Port 6: Dev 126, If 0, Class=hub, Driver=hub/2p, 480M /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M |__ Port 1: Dev 2, If 0, Class=hub, Driver=hub/6p, 480M Also please add an entry into commands/Kconfig: And put it into the info group, lsusb just shows something, it doesn't manipulate any hardware. _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
