| I enabled USB in the kernel, and as it appears to see my camera and scanner. However, I never got an entry in /proc/bus for the usb (I only have pci there). Shouldn't there be one ? |

I think you need to configure "Preliminary USB device filesystem"
into your kenrel.
| Code: | Preliminary USB device filesystem
CONFIG_USB_DEVICEFS:
x If you say Y here (and to "/proc file system support" in the "File
x systems section, above), you will get a file /proc/bus/usb/devices
x which lists the devices currently connected to your USB bus or
x busses, a file /proc/bus/usb/drivers which lists the USB kernel
x client drivers currently loaded, and for every connected device a
x file named "/proc/bus/usb/xxx/yyy", where xxx is the bus number and
x yyy the device number; the latter files can be used by user space
x programs to talk directly to the device. These files are "virtual",
x meaning they are generated on the fly and not stored on the hard
drive.
x
x You may need to mount the usbdevfs file system to see the files, use
x mount -t usbdevfs none /proc/bus/usb
x
x For the format of the various /proc/bus/usb/ files, please read
x Documentation/usb/proc_usb_info.txt.
x
x Please note that this code is completely unrelated to devfs, the
x "/dev file system support".
x Most users want to say Y here. |
