> Greeting All,
I need to write a driver for ISP1760 host controller currently ,
I have read ISP1760 data sheet& linux programing guide.
But I'm new to USB driver programming ,and I mess up with too
many informations I found.
I list my questions below , hope someone can answer for me , or
discuss with me.
Thank you.
Your first answer, before any of the questions: Don't use 2.4.20!! Use
2.6.15 instead.
1) Seems ISP1760 works for USB 2.0 , so I need to use or modify
ehci-hcd module for it.
But it's a non-pci host controller , I saw there is a
usb-ohci-nonpci module in my kernel.
Do I need to use or modify this module too?
You need to use 2.6.15. It already includes provisions for a non-PCI EHCI
driver.
2) Are USB host controller drivers follow similar framework or
running schedule , so can I
just modify echo or ohci driver to work for ISP1760?
In 2.6.15 they do. If the ISP1760 includes an OHCI-compatible interface,
you ought to be able to modify the OHCI driver to work with it.
