I use the usb bus. Mostly it is for a mouse and today, I have installed a scanner. I've read the documentation (yes!) in /usr/src/linux/Documentation/usb/scanner.txt There is a mention about the usbdevfs and an advice to add a line in /etc/fstab. I have added the line "none /proc/bus/usb usbdevfs defaults 0 0", I expected to have access to /proc/bus/usb/devices without any extra manipulation. # /etc/fstab: static file system information. # # /dev/hda2 / ext2 defaults,errors=remount-ro 0 1 /dev/hdc1 none swap sw 0 0 proc /proc proc defaults 0 0 none /dev/shm shm defaults 0 0 none /proc/bus/usb usbdevfs defaults 0 0 At boot time, I get the messages : Mounting local file systems... modprobe: modprobe: Can't locate module shm mount: fs type shm not supported by kernel modprobe: modprobe: Can't locate module usbdevfs mount: fs type usbdevfs not supported by kernel Running dns-clean. It is ok fr shm : I have the same fstab for both 2.2.19pre and 2.4.0-test and I boot 2.2.19pre... And the I've nothing in /proc/bus/usb If I enter the command 'by hand' : mount -t usbdevfs /proc/bus/usb /proc/bus/usb The system accepts the command and I can do a cat /proc/bus/usb/devices : [root@debian-f5ibh] ~ # mount -t usbdevfs /proc/bus/usb /proc/bus/usb [root@debian-f5ibh] ~ # cat /proc/bus/usb/devices T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2 B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0 D: Ver= 1.00 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=0000 ProdID=0000 Rev= 0.00 S: Product=USB UHCI Root Hub S: SerialNumber=6100 C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr= 0mA I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub E: Ad=81(I) Atr=03(Int.)
