Honored ContributorIRQ mapping in SOPC builder
I fixed up the device address (na_usb - to the address assigned to ISP1362 in SOPC builder) and irq (na_usb_irq - IRQ 4 when viewed in SOPC builder) and corrected the chip id so linux recognizes the usb port, but i get the following error about the IRQ after i plug in a USB flash drive. I checked the DE2_NET design I'm using for this experiment in SOPC builder and the IRQ for ISP1362 is 4, or should i instead be using the IRQ for the DMA?

Altera_ForumShindou,
Good found, It looks like the piece of driver you need. you have to update your arch/nios2nommu/kerbel/usb.c to prepare for the probing of the 1362 hcd. You should enable the debug message, too. You have to "port" the driver to your nios2 board. (it is not plug-and-play...). The 1362 hcd should detected first, then the root hub. Then when a usb disk inserted it will detect the new usb mas storage device, and display the usb disk info.- Altera_Forum

Please find the isp1362.zip attached in post#1 of buildroot guide.

it didn't initialize the isp1362-hcd,
Did you select isp1362 hcd in kernel menuconfig? Try add some printk and debug to the code, arch/nios2nommu/kernel/usb.c and drivers/usb/host/isp1362-hcd.c . - Altera_Forum
It seems like it's getting to the usb_hcd_init() call in arch/nios2nommu/kernel/usb.c where platform_device_register(&isp1362_hcd) is called but it seems the init code in drivers/usb/host/isp1362-hcd.c (ie. isp1362_init() is never called)
last edit: Yep, ISP1362 HCD is selected in the menuconfig - hmm, interesting point tho, there's no object file after the make (ISP1362-hcd.o) in the drivers/usb/host directory. It's strange tho, the code in an adjacent directory drivers/usb/core had object files. Probably explains the problem above why that code never got called. Gonna see if i can figure out why this makefile isn't compiling isp1362-hcd.c. - Altera_Forum
try make clean, and rebuild kernel from hwselect again.
I did try compile with DE2 ptf . there should be the isp1362-hcd.o . - Altera_Forum
Found the problem, the Makefile in the drivers/usb didn't point to the drivers/usb/host directory for ISP1362 selection in menuconfig.
