using the PICkit? Serial Analyzer and how to resolve them.
FREQUENTLY ASKED QUESTIONS
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 ? operating system Device Manger by clicking on Control Panel >
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.

WINDOWS ? DEVICE MANAGER
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 ? Windows ? 98 SE
Question
After plugging the PICkit? Serial Analyzer into the USB port, Windows ? 98 SE asks
for a driver. Where is the driver?
Answer
PICkit? Serial Analyzer uses the Human Interface Device (HID) driver included with
the Windows ? Operating System. When Windows ? 98 SE prompts for a driver, select
“Search for the best driver for your device.” Then select the check box next to “Microsoft
Windows Update” and click Next. Windows will automatically install the appropriate
driver. Do not use Microchip’s MPLAB ? ICD 2 USB driver.
