Update: this works until device disconnect only. After reconnect IDE could hang up :-)
Update: added string for HTC Desire Z

Ubuntu 10.04/android sdk 7(9? where the f%%k is sdk version? no version in readme! opensource sometimes is such an opensource.)

When you see such f%%% sh%%%:

./adb devices
List of devices attached
???????????? no permissions

To be able to deploy to samsung galaxy tab do the following:
1) create new file (51 is just some number below 99):
sudo vi /etc/udev/rules.d/51-android.rules
and put there:

SUBSYSTEM=="usb", SYSFS{idVendor}=="04e8", MODE="0666"
SUBSYSTEM=="usb", SYSFS{idVendor}=="18d1", MODE="0666"

04e8 is samsung id
18d1 is for HTC Desire Z
2) restart adb daemon:
sudo ./adb kill-server
sudo ./adb devices
you now should see this:

* daemon not running. starting it now on port NNNN *
* daemon started successfully *
List of devices attached
10001c18352d device

If above still doesn't help add more detailed description for usb device in 51-android.rules like this

SUBSYSTEMS=="usb", ATTRS{idVendor}=="0bb4", ATTRS{idProduct}=="0c91", MODE="0666"

here 0c91 is the HTC Desire Z product id. You can watch these details using 'lsusb' command:

Bus 002 Device 011: ID 0bb4:0c91 High Tech Computer Corp.

Yesterday made simple experiment: recorded in log coordinates (x,y) of pointer press, drags and release events at real devices. During experiment I only clicked (not scroll!) at screen using finger. Devices are: Nokia 5230 and Samsung S5230.
Results impressed me a lot: bounce is up to 23 pixels (for y up to 15, possibly because of finger shape)!
This mean that if you need to differentiate scroll from click, you have to implement some kind of filter that takes into account time and type of movements of pointer.
