I have updated my two computers with kernel 2.6.6 from my RedHat 9 kernel 2.4.20-8. One is laptop and another one is Desktop.


However both of my computers are not working with my USB Floppy deive, usb mouse, and usb webcam. It can't detect any devices whenever I plug in any usb devices. I have gone through my .config. I make sure my plug and play=y, and my CONFIG_USB_DEVICEFS=y, and CONFIG_USB=y. It works perfectly in my kernel 2.4.20-8, but won't work on my kernel 2.6.6 I have tried so many ways, changed the config file and recomplied so many times, and have been reading so many articles regarding to the usb setting. I have been trying for a month and staying very late at night to try to make my all usb devices work. Still I can't make my USB ports work in my both computers.
Also my DVD/CDRWs are not working in my both computers. I checked up ftab files, they even not shows up in ftab files.
I almost want to give up to update to the kernel 2.6.6



Could somebody tell me what is the best way to modify my .config or change other files to make my usbs and DVD/CDRW work?
