 Posted: Sat Jun 30, 2012 4:35 pm Post subject: linux kernel requirements for adb (android debug)? |
 |
|
I'm trying to connect to my android phone with adb.
The kernel I'm actually using is a gentoo-sources-2.6.36-r5. I'm sure I was able to connect to my phone a few months ago. It's possible I screwd up kernel configuration 
On a ArchLinux it works (so it does not seems a phone-related problem).
On my gentoo, the phone, once it's connected, starts charging but no notification appears (two notification are meant to popup: "usb connected" and "debug activated".
I found on google a suggestion to activate USB gadget support, anyway it doesn't change.
Can you help me, please?
Thank you!
MJ

You might want to check the last several lines in the kernel log buffer, i.e.
and make sure your device is being detected properly.
For reference, here are the activated USB-related kernel options on my computer, on which adb works for me:
| Code: | CONFIG_V4L_USB_DRIVERS=y
CONFIG_USB_VIDEO_CLASS_INPUT_EVDEV=y
CONFIG_USB_GSPCA=m
CONFIG_USB_GSPCA_SN9C20X=m
CONFIG_SND_USB=y
CONFIG_USB_HID=y
CONFIG_USB_HIDDEV=y
CONFIG_USB_SUPPORT=y
CONFIG_USB_COMMON=y
CONFIG_USB_ARCH_HAS_HCD=y
CONFIG_USB_ARCH_HAS_OHCI=y
CONFIG_USB_ARCH_HAS_EHCI=y
CONFIG_USB_ARCH_HAS_XHCI=y
CONFIG_USB=y
CONFIG_USB_DEBUG=y
CONFIG_USB_ANNOUNCE_NEW_DEVICES=y
CONFIG_USB_DEVICEFS=y
CONFIG_USB_MON=y
CONFIG_USB_EHCI_HCD=y
CONFIG_USB_OHCI_HCD=y
CONFIG_USB_OHCI_LITTLE_ENDIAN=y
CONFIG_USB_UHCI_HCD=y
CONFIG_USB_SL811_HCD=y
CONFIG_USB_PRINTER=y
CONFIG_USB_STORAGE=y
CONFIG_USB_LIBUSUAL=y |
I am pretty sure thsoe are all the defaults; I doubt that I changed anything or else I would have removed CONFIG_USB_PRINTER and CONFIG_V4L_USB_DRIVERS.

| Afaik, adb uses libusb and does not have any specific kernel requirements (other than CONFIG_USB_DEVICEFS=y). Gadget support is only for running a linux kernel on a USB "client" device (as opposed to a USB host) and will not help. Is your user in the android group? |
