I guess it helps to know some history. usb-uhci came from Deti/Georg/Tom, whose web site is now at: http://wwwbode.cs.tum.edu/Par/arch/usb/ so look in Download for the usbstress package and it has a uhcidump program. -- ~Randy kernel-janitors project: http://janitor.kernelnewbies.org/ ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
