 |
|
When I plug in a USB device, the kernel doesn't do anything with it, I get no log messages. I must be missing something stupid, but I can't figure it out. I should note I had this working on this system (amd64, nvidia nforce3-250 chipset) before my HD crashed and I had to reinstall gentoo.
kernel has USB support:
| Code: | % grep USB /usr/src/linux/.config | grep -v \#
CONFIG_USB_ARCH_HAS_HCD=y
CONFIG_USB_ARCH_HAS_OHCI=y
CONFIG_USB=y
CONFIG_USB_DEVICEFS=y
CONFIG_USB_EHCI_HCD=m
CONFIG_USB_OHCI_HCD=m
CONFIG_USB_OHCI_LITTLE_ENDIAN=y
CONFIG_USB_UHCI_HCD=m
CONFIG_USB_PRINTER=y
CONFIG_USB_STORAGE=y
CONFIG_USB_HID=y
CONFIG_USB_HIDINPUT=y
CONFIG_USB_EGALAX=m
CONFIG_USB_OV511=m
CONFIG_USB_MON=y
CONFIG_USB_LEGOTOWER=m
CONFIG_USB_CYTHERM=m
CONFIG_USB_PHIDGETSERVO=m
|
kernel has hotplug support:
| Code: | % grep HOTPLUG /usr/src/linux/.config | grep -v \#
CONFIG_HOTPLUG=y
|
Hotplug is set to start on boot:
| Code: | % /etc/init.d/hotplug status
* status: started
|
log messages show usb system initializing itself:
| Code: | % dmesg | grep -i usb
usbcore: registered new driver usbfs
usbcore: registered new driver hub
usbmon: debugs is not available
usbcore: registered new driver usblp

ehci_hcd 0000:00:02.2: USB 2.0 initialized, EHCI 1.00, driver 10 Dec 2004

|
After powering on my USB printer and connecting my digital camera (powershot A40) via USB, I get no additional log messages. Also:
| Code: | % cat /proc/bus/usb/devices
T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 8
B: Alloc= 0/800 us ( 0%), #Int= 0, #Iso= 0
D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=01 MxPS= 8 #Cfgs= 1
P: Vendor=0000 ProdID=0000 Rev= 2.06
S: Manufacturer=Linux 2.6.12-gentoo-r6 ehci_hcd
S: Product=nVidia Corporation nForce3 EHCI USB 2.0 Controller
S: SerialNumber=0000:00:02.2
C:* #Ifs= 1 Cfg#= 1 Atr=e0 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.) MxPS= 2 Ivl=256ms
|
So, usb-devfs is working, but only the hub is present.
I have tried unmerge/remerge libusb and hotplug, no joy.
I'd be glad for any ideas!
thanks,

Hotplug doesn't load usb_ohci, usb_ehci, or usb_ehci on my machine either.
How would it, if the bus isn't up.
usb_storage and usb_hid should load with hotplug when needed.
BTW you only need ohci or uhci. |

I don't understand. The bus *is* up. It's the only thing up.

usb_storage and usb_hid are compiled into my kernel, they are not modules.

Update: On a whim, I recompiled the kernel, making usb_storage and usb_hid modules. It made no difference.
If anyone has an idea why my hotplug is completely silent, I'd love to hear it...
