Try a Wacom next time.
I recently (less than a week ago) purchased a Huion K58 graphics (or Pen) tablet. It's one of those tablets that is usually used for drawing, handwriting on a PC etc...
The problem I am having with it is that, while I'm working with it, it will all of a sudden stop working and every time it does that I have to spend about half an hour to an hour uninstalling and re-installing the drivers; unplugging and re-plugging the tablet; changing the USB port; restarting the PC etc... It is really annoying.
Sometimes it will work fine at night and when I go to bed and wake up the next morning, I find out that it doesn't work and I have to go through the same process to fix it.
I tried using the drivers that come with the CD, I tried downloading the latest drivers from their website; I even tried using it without a driver (it works, because windows 7 apparently can recognize it, but some of the features are unavailable -like pressure sensitivity), and it still keeps doing the same thing.
When it's working, working the tablet seems to be doing fine and I love it but when it's not it really pisses me off.
If anyone has some insight of how to permanently solve this problem, please help! I think it is a software/driver issue, because I read many people had the same problems when they first bought tablets from this company.
Thanks in advance.
