QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 590B
USB SERIAL CONTROLLER FOR LINEAR TECHNOLOGY QUICKEVAL™ DEMO BOARDS
TROUBLESHOOTING GUIDE
Problem: DC590B is plugged in, but QuickEval
screen still says “USB Serial Controller Not Con-
nected”
Solution: The most likely cause is improper instal-
lation of the USB drivers, which causes Windows
to recognize DC590 as an “Unknown Device.”
Open the Windows Control Panel, open “System”
and click the “Device manager” tab. Open the
“Other Devices” item and look for USB SERIAL
CONTROLLER. Select this item and click the re-
move button. Unplug DC590, Re-install the
QuickEval software, and follow the on-screen in-
structions.
Problem: Demo board software loads properly,
but will not run or gives “Device Not accessible”
errors.
Solution: Verify that the demo board is properly
powered up. This Quick Start Guide lists the basic
power connections to DC590. Some demo boards
may have additional requirements; refer to the
demo board’s Quick Start guide for details.
Problem: After connecting the demo board to
DC590 with the supplied 14 pin ribbon cable,
QuickEval software still displays “Evaluation Board
is not Connected.”
Solution: Contact Linear Technology Applications
Engineering.
