It's hard to do a direct comparison because USB Snoopy only recorded the URBs meant for the touchpad whereas usbmon recorded everything sent to the device, including URBs for the keyboard. So we don't know what Windows was sending to the keyboard. Is it possible for you to tell USB Snoopy to record everything going to either the keyboard or the touchpad? Maybe there's some weird interaction between the two. As far as the touchpad part is concerned, the two logs are identical except for one part. Near the end of usb_hid_configure() there's a call to usb_clear_halt(). It should be harmless, but Windows doesn't do the equivalent. So try commenting out that call. > No output generated when pressing touchpad buttons or finger on pad. That's the other difference between the two logs. :-) > Pressing "k" on the keyboard produces 4 lines of data as follows. > > f6acf1c0 2422482633 C Ii:019:01 0 8 = 00000e00 00000000 > f6acf1c0 2422482861 S Ii:019:01 -115 8 = 00000e00 00000000 > kf6acf1c0 2422546627 C Ii:019:01 0 8 = 00000000 00000000 > f6acf1c0 2422546844 S Ii:019:01 -115 8 = 00000000 00000000 > > From what I read in the docs on usbmon, the last line avove is specific > to the 2nd interface which is the mouse.

That line is where usbhid is asking the touchpad to report on any events that happen. The touchpad doesn't send back any reports in response when you do something. Without a complete log from Windows we can't be sure of anything. Try getting rid of the usb_clear_halt -- although that was just added in 2.6.15 so it wouldn't have affected anything you tried using earlier kernels. For what it's worth, I've got a USB keyboard (sold by HP) that works if the clear_halt is present or if init_reports is missing, but doesn't work when the clear_halt is missing and init_reports is present.
