The following is an extract from doing "ls -Rl /sys" on my system. At first glance, this directory can seem quite confusing. Since USB devices are connected through a host controller via the PCI bus, they can be found in /sys/devices/pci0000:00 which lists directories for each numbered PCI device. My motherboard has three host controllers, EHCI, OHCI, and UHCI, connected respectively to 03.0, 03.1, and 03.1 addresses of the primary PCI bus 0000:00. These correspond to usb busses 001, 002, and 003.
Since the EHCI, OHCI, and UHCI controllers are also bus devices, links to them can be found in /sys/bus/pci/devices. Similarly, since they are also USB bus devices, links to them can also be found in /sys/bus/usb/devices.
In this listing, my camera was automatically connected to the UHCI controller (USB bus 003) as device 2, and my two small storage devices were connected as devices 003 and 005 on the EHCI controller (USB bus 001). The storage devices, however, were recognized as disks and are also represented as links under /sys/block/sda/device and /sys/block/sdb/device with their single primary partition information listed under /sys/block/sda/sda1 and /sys/block/sdb/sdb1, respectively. Furthermore, since they are set up as SCSI devices, they are also represented as links under /sys/bus/scsi/devices.
