This page summarizes the informations to use the DevFull's ISP1761 USB Host controller with Linux.

Compilation

• Launch kernel configuration:

$ make linux-menuconfig

• Activate USB support in Linux:

Device Drivers  ---> USB support  ---> <M> Support for Host-side USB

• and choose ISP1761 controller:

Device Drivers  ---> Armadeus specific drivers  ---> <M>   isp1761 USB 2.0 Host controller

• then, depending on the devices you're planning to plug, you will have to add some more USB drivers.

Usage

• Three drivers have to be started in order to get the ISP working. They have to be started in the following order:

# modprobe apf9328-isp1761
# modprobe hal_imx
# modprobe pehci

• or put them in a bash script in /etc/init.d:

#!/bin/sh
modprobe apf9328-isp1761
modprobe hal_imx
modprobe pehci

• and then you should see (on console):

isp1761 isp1761.0: PHILIPS ISP1761
isp1761 isp1761.0: new USB bus registered, assigned bus number 1
isp1761 isp1761.0: irq 138, io mem 0x00000000
