How to identify USB connction on MAC
To check if there is a physical connection for TS1.
This is done viewing the System Report.
- Click on the Apple logo in the upper left corner then select About This MAC.
- Select System Report.
- In the under Hardware section, click on USB.
- Expand the USB Device Tree and locate C-Pen TS1.
If C-Pen TS1 exist, then the physical connection is OK.
If the C-Pen TS1 does not exist there is a physical connection problem. Try to connect the TS1 to another USB port and/or test it on another computer to verify it.
NOTE: System Report\Hardware\USB list will have to be refreshed at each new connection. Exit it an re-enter the USB Device Tree list.
Assuming that the C-Pen TS1 does exist in the USB Device Tree, then the problem is caused by software.
