Wavy line USB issue

Postby PeterKelly » Mon 25. Sep 2017, 11:00

Cintiq 24HD

Clearly, this is not a new issue as there have been many other posts, even in the previous version of the forum, so will Wacom please fix it???!!!??

As anyone who uses such tablets will almost certainly have experienced, when you first begin working the pen can draw perfectly straight lines, but if you let your machine hibernate and begin work again after waking, slow lines create waves (

As mentioned in the comments, the fix is to remove the USB lead and replace it, but this is a PITA and not a fix. Will Wacom ever release a driver that doesn't display this problem?

After return from sleep, USB ports may sometimes work only in a low speed mode. When less data is passing through USB, you can get wavy lines. USB ports are handled on the hardware level by the operating system (and low level USB drivers). The tablet driver may not be aware of that. When you unplug and replug the cable, the port and speed are re-initialized. - For Windows systems you can go to device manager -> USB -> root hub -> properties -> power management and turn off 'Windows can turn off device to save power'.
