to hippo:

the uclinux driver about usb host is a common driver,or not?

is this driver only support the usb2.0 ip core ? can this driver driver the usb host on arm?

if i want to write the registers of usb2.0 ip core,iit means that i can find such case"iowr(base, reg, data)" on the driver. but i can't.

do you know how the ucliux solve this?

thank you!!

The ISP1761 dose not need USB 2.0 IP core. They are two different things.

The USB has two functions, host and device. You need to know which one you want.

The ISP1761 is a common part, which you can use on most embeded processors, including ARM, BF etc. There is a Linux host and device driver on sourceforge from the vendor , NPX.

I don&#39;t know which USB 2.0 IP core you are refering, but it is not easy to write a USB driver.

The port io functions are defined in linux-2.6.x/include/asm-nios2nommu/io.h .
