HiPen H3 stopped working after Win10 upgrade

After a recent Win10 upgraded, the HiPen H3 has stopped working.
Touch screen seems to be working - using finger, and back of the stylus. But using the stylus tip, there is no response.

After looking through some of the recent topics, I’d like to try updating the driver.

The UBook was a reward via Kickstarter (8GB/256GB version).
The back of the device says Ubook Q128G519030878

BTW, is there a user guide for the HiPen H3??

You should install driver.UBOOK drivers
