The HX3 board does
not power on.
CY4609,
CY4603, and
CY4613
The jumper on the current mea-
surement header may not have
been installed.
Ensure that the jumper on the current
measurement header (J2 on CY4609,
J6 on CY4603, and J20 on CY4613) is
connected correctly.
If you are holding the HX3
board, you may be touching the
crystal area on the board. Remove the contact on the crystal and
power on the board. See
Figure 3-4 on
page 19 for the crystal location.
Only the USB 2.0 hub
entry appears in the
Device Manager (on
Windows operating
systems) when the
HX3 board is con-
nected to the PC.

CY4613
The PC USB port may not sup-
port USB 3.0 capability. Ensure that the PC has USB 3.0 spec-
ification-compliant ports.
The USB cable used to connect
the HX3 hardware may not sup-
port USB 3.0 capability. Ensure that the USB cable provided
with the Cypress kits or cables sup-
porting USB 3.0 capability are used.
The USB device driver installed
on the PC may not support USB
3.0 capability.
Check whether the device driver
installed on the PC supports USB 3.0
capability. Fix the device driver if
required.
Port status indicator
LEDs do not work. CY4603 and
CY4613
If the port status indicator LED
is shared with the pin strap fea-
ture, a jumper associated with
that pin strap may have been
installed.
See Table 3-7 on page 30 to check if
the port status indicator LED is shared
with a pin strap. If it is shared, ensure
that the pin strap is strapped to logic
‘0’ or ‘1’ as described in
“Configuring
HX3 Using Pin Straps on CY4603” on
page 34
. The pin strap jumper needs
to be installed tightly even though the
pin strap feature is not enabled using
PIN_STRAP_EN (J13).
When a USB 3.0
device is connected
on a downstream
port, the green port
status indicator LED
glows instead of the
blue LED.
CY4603 and
CY4613
The hardware might be operat-
ing in the USB 2.0 mode
because the USB port on the
PC may not support USB 3.0
capability.
Ensure that the USB port on the PC
supports USB 3.0 capability. Other-
wise, the CY4603 hardware will oper-
ate in the USB 2.0 mode only.
