Stylus not working on U book Pro

i just receive my new purchase chuwi U book type cw1535

the active stylus pen I used with my HI 13. does not work on this device. it’s not “seen” by this system so what can I do ?? its brandnew out of the box

Maybe it’s missing the driver for old pen, Ubook Pro can use HiPen H3 and H6 without trouble.

yes perhaps but where can I get the driver from ?

Got the same problem. Cant see it or find it via Bluetooth. Which styluses are compatible with UBook Pro 8100y? I’ve got old h2 pen.
