Windows 7 HID drivers are checking on or doing something more stringent than Windows XP related to power.
Since the only change is the OS, this must be a driver issue. Notice how the Generic USB hub (which belongs to the Dell 1907FP display) is gone:īut, nothing on the forums could explain why the tablet was working fine under Windows XP. I connected the Wacom tablet directly to my PC case with a USB cable and the USB connection hierarchy reduced by a level. So, it is a power issue! Connecting the Wacom tablet through a USB hub is reducing the power available to the tablet. In order to make sure that the tablet is supplied with sufficient power, please connect it directly to a free port of your computer, not via a USB hub. This is the USB connection hierarchy to my Wacom tablet:Īnother post on the Wacom forums explained why the tablet will not work properly if connected through a USB hub:Ĭause might either be that the tablet does not get sufficient power or that Windows can not find it's HID drivers which a mandatory for the Wacom driver to connect to the tablet and operate properly. That reduces clutter on the desk and frees up precious desk space. The reason I need to do this is because I like to keep my PC case below the desk. Voila! My Wacom tablet is actually connected through a USB hub! The USB hub is in my Dell 1907FP display, which is connected by a USB cable to my PC case. Make sure to connect the tablet to a USB port in the back of the machine and not through a hub or other USB extension. I reboot the computer, sometimes this works, but sometimes even this does not unfreeze it! This problem was puzzling me for a while, until I ran across this post in the Wacom forums: I unplug the tablet and plug it back, no change. The problem is that sometimes the Wacom mouse cursor just freezes up. I have ensured that I have the latest Wacom drivers installed (v5.2.1-6) meant for Windows 7. My Wacom Bamboo Fun which was working fine for more than a year with Windows XP continues to have problems with Windows 7. ? 2010-Jan-18 ⬩ ✍️ Ashwin Nanjappa ⬩ ?️ usb, wacom bamboo fun, windows 7 ⬩ ?
