 |
|
I switched to udev recently. Note, however, that I never messed with usb in devfs. I didn't bother using it.
I can't get my usb ports to show up in /dev. They're in the kernel, etc. I've got usbutils-0.71-r1 installed. they show up as follows in lsusb:
| Code: | # lsusb -t
Bus# 2
`-Dev# 1 Vendor 0x0000 Product 0x0000
Bus# 1
`-Dev# 1 Vendor 0x0000 Product 0x0000
|
Note, mobo is an Asus A7M266.[/code]
lspci gives the following:
| Code: | 00:04.2 USB Controller: VIA Technologies, Inc. USB (rev 16) (prog-if 00 [UHCI])
Subsystem: VIA Technologies, Inc. (Wrong ID) USB Controller
Flags: bus master, medium devsel, latency 32, IRQ 9
I/O ports at d400 [size=32]
Capabilities: [80] Power Management version 2
00:04.3 USB Controller: VIA Technologies, Inc. USB (rev 16) (prog-if 00 [UHCI])
Subsystem: VIA Technologies, Inc. (Wrong ID) USB Controller
Flags: bus master, medium devsel, latency 32, IRQ 9
I/O ports at d000 [size=32]
Capabilities: [80] Power Management version 2 |
Why does it say Wrong ID? Any ideas?
Many thanks! |

| My impression was that you find anything in your /dev until you plug something into one of the ports. IE: plug in an external usb drive and you find a /dev/sda entry. Plug in a joystick and you'll have a /dev/input/js0. What specifically are you looking for in /dev? |

A camera (effectively, a USB hard drive). I plug it in and can't find any difference (using diff -y -suppress-common-lines) between the available devices. I do have sda entries available, but how do I determine which is the camera?
| Code: | # lsusb
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 003: ID 04cb:0171 Fuji Photo Film Co., Ltd
Bus 001 Device 001: ID 0000:0000 |

If the scsi device is /dev/sda then do: | Code: | | $ udevinfo -a -p $(udevinfo -q path -n /dev/sda) |
This will tell you information about that device. Then use this info to create a special rule in the /etc/udev/rules.d/10-local.rules file. For example I have: | Code: | | BUS=="usb", SYSFS{serial}=="0002F5DAD228848B", NAME="muvo" |
which causes udev to create a device /dev/muvo whenever my muvo mp3 player is plugged in. Then KDE automounts that device to /media/muvo which removes all ambiguity. |
