USB tether btw Tablet and Phone

Hi everybody,
sorry if may i do not write propely but my english is not perfect.
Hi looked around for trying to connect my ChinaPad with Gingerbread 2.3 to my Sony Xperia X8 for using its internet connection.
Wifi tether has some problem, even using barnacle wifi, usually i use easy tether USB for doing that with the laptot and its work fine.
Now i got this tablet and i would like do the same with it, by bluetooth or usb.
Anyone know if its possible or not doing that??

Thanks.
