FREQUENTLY ASKED QUESTIONS
This chapter describes questions and answers to common problems associated with
using the PICkit™ Serial Analyzer and how to resolve them.
PICkit™ Serial Analyzer could not be found
Question
I am receiving the error message, “PICkit™ Serial Analyzer could not be found” in the
Transactions window, but the PICkit™ Serial Analyzer is plugged in. What is wrong?
Answer
Open the Windows
System, selecting the Hardware tab and clicking on Device Manger button. Check if
there is an error displayed under Human Interface Devices as shown in Figure 11-1.
If an error is displayed, try unplugging and the re-plugging the USB cable until the error
goes away (this may take 3 or 4 tries).
If the error persists, try another USB port or hub. Try plugging the PICkit™ Serial
Analyzer into another computer to verify that the USB port is working.

Current Limit Exceeded
Question
I received the error message “USB Hub Current Limit Exceeded” from the Windows
operating system. What is wrong?
Answer
The USB port current limit is set to 100 mA. If the target device plus PICkit™ Serial
Analyzer exceeds this current limit, the USB port will shut down. Check for shorts. The
target device can be externally powered if more power is needed.
Microsoft
Question
After plugging the PICkit™ Serial Analyzer into the USB port, Windows
for a driver. Where is the driver?

PICkit™ Serial Analyzer uses the Human Interface Device (HID) driver included with
the Windows
