How to get bluetooth mouse working with SGS Tab 10.1

Question

Android

The mouse spits (connects). But the cursor does not appear on the screen.
Samsung galaxy tab 10.1 (p7500). Mouse speedlink SL-6158-sbk. Android 3.2

The same mouse on Samsung gallaxy S2 with Android 4.1.2 works without problems.

You can certainly roll 4.1.2 on the tablet, but I want to wait for the official update.

What do you advise? maybe there is some app to solve this problem. Tried blueinput app. Did not help.

Thank you.
