I have a similar problem, so my experience may be relevant. Then again, it may not. But it is worth a try.
I am running not on Ubuntu, but on Fedora. And when I first establish the connection, I often don't see the device, but get the row of question marks you describe. Usually, but not always, I can solve this by restarting the adb server. Sometimes I have to do it twice. I usually do this while in superuser on my Fedora system. Sometimes even doing it twice is not enough, and I don't remember what I last did before it finally started working;) On Sep 18, 6:03 am, Mark <[email protected]> wrote: > Hi developers, > > I try to setup an adb connection through USB but keep on running into > problems. > > If I run the adb deamon as a regular user (not as root) and run "adb > devices" I get: > > List of devices attached > > > ???????????? no permissions > > This is documented on the web and should be fixed by adding a udev > rule on my ubuntu machine in /etc/udev/rules.d/51-android.rules: > SUBSYSTEM=="usb", ATTRS{idVendor}=="0bb4", ATTRS{idProduct}=="0c01", > MODE="0666" > > But when i add this rule the list of devices I get from "adb devices" > is empty. > > I also tried running the adb deamon as root but the device list is > still empty. > > lsusb list the zt-180 device (after I plugin the usb connector) as: > Bus 002 Device 013: ID 0bb4:0c01 High Tech Computer Corp. > > I noticed that there is a standard rule for the same vendor/product-id > in /lib/udev/rules.d/40-usb-media-players.rules which says: > ATTRS{idVendor}=="0bb4" , ATTRS{idProduct}=="0c01|0c02|0c13" , > ENV{ID_MEDIA_PLAYER}="high-0c01_0c02_0c13" > ENV{UDISKS_PRESENTATION_ICON_NAME}="phone-htc-g1-white" > > There is one error in my deamon.log that might have something to do > with it, but I'm not sure (and I don't know how to fix it either): > usb_id[3793]: unable to access '/devices/pci0000:00/0000:00:1d.1/ > usb2/2-1' > > Does anyone know what's going on? > > -Mark- -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
