#23 make lsusb -t work with recent kernels (without usbfs)

[Anonymous]

Same feature request as 1838556. The original reporter said it was fixed in newer versions, but I believe this is not the case. Some distributions patched, but the patches were not merged upstream.

Here's what happens:

[22:12 TA|catwell] lsusb -t
cannot open /proc/bus/usb/devices, No such file or directory (2)

Note that it does work if you mount usbfs, but the point here is to make it work with sysfs.
