I tried different ROMs:
On Cromi-X 4.7.0 docking tablet causes it to freeze. Screen and hard buttons are not reacting (unless you do hard reboot). When I remove tab from dock it unfreezes and performs actions which were issued when in dock.
On Cromi-X 5 (latest version) it's not working at all, it is not recognised. It charges pas but there is nothing in notification area and keys are not working. Tablet uses screen keyboard.
Same goes for Crombi.
Anybody have idea what can be wrong?
