I think I may have found a bug in the 2.6 kernel and am hoping someone can help me find what's causing the problem so it can be solved. Basically, I have a wireless keyboard and mouse which works via one USB connection (I can only assume it uses a hub) which work fine under 2.4 but in 2.6 the mouse jerks. It doesn't move smoothly from point A to point B it jerks there. The mouse works fine in NetBSD too which is what's leading me to believe it's a bug in the 2.6 kernel.
I've tried multiple configurations and loading and unloading many different modules to try and find out if something is conflicting or what's causing it but can't find anything. I've also tried using non vanilla kernels such as Mandrake's, Red Hat's, Gentoo's and SuSE's but I still get the same problem.
This is the output from lsusb in 2.4...
Bus 004 Device 001: ID 0000:0000 Bus 003 Device 001: ID 0000:0000 Bus 003 Device 002: ID 041e:3020 Creative Technology, Ltd Bus 002 Device 001: ID 0000:0000 Bus 002 Device 002: ID 04b8:0005 Seiko Epson Corp.

...and this is the output from lsusb in 2.6...
Bus 004 Device 001: ID 0000:0000 Bus 003 Device 002: ID 041e:3020 Creative Technology, Ltd Bus 003 Device 001: ID 0000:0000 Bus 002 Device 004: ID 0419:0600 Samsung Info. Systems America, Inc.

I don't know which one of those it will be though. Although the keyboard and mouse are Creative Labs I'm assuming the Creative one showing is my sound card (SB Audigy2 NX) because that works fine. Epson is the printer obviously so it must be the Samsung thing. Strange considering it's made by Creative Labs.
Just another note. Under FreeBSD and NetBSD the devusb command shows it up as a wireless keyboard and mouse. I don't suppose this would make a difference though.
