I am almost 100% sure that it is an MSI or Intel chipset. Nearly every device is from Intel anyway... dmidecode calls it MS-7204. I can try 2.5 kernels, but will they boot my system to a prompt med udev/hal etc..? Do you have an idea as to how I can make a 2.5 friendly environment if udev/hal is not well supported in 2.5? Which 2.5 kernels would you suggest? One in the lower end I suppose and maybe of of the last ones? ----- Original Message ----- From: "Oliver Neukum" <oneukum@suse.de> To: "Martin Møller" <martin@mail.martinm-76.dk> Cc: opensuse-kernel@opensuse.org Sent: 29. august 2007 07:36:51 (GMT+0100) Europe/Berlin Subject: Re: [opensuse-kernel] Issues with USB 2.0 on one machine.

Okay.. These are my results:
I was wrong about 2.6.5 -- It also says port 2 is bad, as does 2.6.4 and 2.6.12 and every other 2.6.x kernel that loads ehci-hcd. For all the 2.6 kernels, the load was at 1 or higher with ehci-hcd loaded and nothing going on... I tried: SuSE Linux 9.1, SLES9 SP1, Knoppix 4
You have khubd running non stop.
However, both 2.4.21 and 2.4.27 kernel work fine (but cannot see my harddisks, save the USB one, for lack of SATA support) Mounted one USB partition with the 2.4.27 kernel from GamesKnoppix I and wrote the attached files to the USB disk.
Can you bisect through 2.5 ?
2.4 distros: GamesKnoppix I, UnitedLinux SP3.
So I guess that means that SuSE Linux 9.0 was the last time I had functional USB 2.0 speed without workarounds... How time flies...
Something must have changed dramatically going to 2.6 for the ehci-hcd driver...
There's no indication the change must have been dramatic to cause this. Are you using a VIA chipset? Regards Oliver
