USB Example

Altera_Forum · ‎08-28-2013

Hello all,

I am using the stratix IV DE4 development board and am having some troubles with the USB example project shipped on the CD, the usb chip is the isp1761.

The project compiles and nios2 run successfully and the debug screen asks to insert a USB mouse or storage device, however nothing happens when I plug them in. Even the 3 leds (vbus1,vbus2,vbus3) are not lighting up, they do however light up when I run their demo batch file(provided on shipped CD) and attaching usb mouse/storage device are able to work from there.

Here is the output when I run there example project(adding in some extra debug print):

===== DE4 ISP1761 USB Host Demo =====
32 bit bus
Port 1 as host
ISP1761 (SCRATCH register pass)
hcInitReg
Check chip ID
 matched chip id
hcReset
Port 1 configured as host
Set hub device address success, address=1
Set Config, HubAddr=1, ConfigValue=1
--------------- Get Hub Descriptor (Addr=1) ---------------
Please insert USB-Storage or/and HID USB-Mouse

Leds dont light up, and doesn't respond when i insert a device.

I am missing something?

Hi

I am working on the usb device project on the DE4 board on window 7.

But when loading .sof and elf files, the driver is not supported on win7.

Can anybody help me fix this?
