    USB 1.1 support in 2.6 kernel


    hi all,

    I am having a device driver which is used in kernel 2.4 for two different usb1.1 devices (i build two drivers using same source using conditional macros). Now i want to upgrade that driver for 2.6 kernel. here one of the device is usb 2.0 and other is usb 1.1. i would like to know if it is possible to use the usb 2.0 driver for usb 1.1. if not how can i write a driver for usb 1.1 in kernel 2.6.

    please help me...

    regards

    In linux-2.6 you use uhci or ohci drivers for usb 1.1, depending on your controller. Then, in top of these, you use ehci for usb 2.0.
