It's different, but I'm not sure if it's better: sarah@xanatos:~/git/logs/2010-04$ ~/git/lsusb/lsusb Bus 001 Device 001: ID 1d6b:0001 Linux 2.6.34-rc4-ss-desc uhci_hcd Intf 1-0:1.0 (hub) Bus 002 Device 001: ID 1d6b:0002 Linux 2.6.34-rc4-ss-desc ehci_hcd Intf 2-0:1.0 (hub) Bus 003 Device 001: ID 1d6b:0001 Linux 2.6.34-rc4-ss-desc uhci_hcd Intf 3-0:1.0 (hub) Bus 003 Device 002: ID 08ff:2810 (null) Intf 3-1:1.0 ((null)) Bus 003 Device 003: ID 0a5c:2145 Lenovo Computer Corp Intf 3-2:1.0 ((null)) Intf 3-2:1.1 ((null)) Intf 3-2:1.2 ((null)) Intf 3-2:1.3 ((null)) Bus 004 Device 001: ID 1d6b:0002 Linux 2.6.34-rc4-ss-desc ehci_hcd Intf 4-0:1.0 (hub) Bus 005 Device 001: ID 1d6b:0001 Linux 2.6.34-rc4-ss-desc uhci_hcd Intf 5-0:1.0 (hub) Bus 006 Device 001: ID 1d6b:0001 Linux 2.6.34-rc4-ss-desc uhci_hcd Intf 6-0:1.0 (hub) Bus 007 Device 001: ID 1d6b:0001 Linux 2.6.34-rc4-ss-desc uhci_hcd Intf 7-0:1.0 (hub) Bus 008 Device 001: ID 1d6b:0001 Linux 2.6.34-rc4-ss-desc uhci_hcd Intf 8-0:1.0 (hub) Bus 009 Device 001: ID 1d6b:0003 Linux 2.6.34-rc4-ss-desc xhci_hcd Intf 9-0:1.0 (hub) Bus 009 Device 002: ID 05e3:0608 (null) Intf 9-3:1.0 (hub) Bus 009 Device 003: ID 15ca:00c3 (null) Intf 9-3.1:1.0 (usbhid) Why are there lots of nulls?
