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 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. 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... /Martin. ----- "Oliver Neukum" <oneukum@suse.de> wrote:

That would be a solution of last resort. I'd rather ratelimit the printk.
Please make sure about 2.6.5. Narrowing this down would be necessary. 2.4 had USB 2.0 support since at least 2.4.21 (Oldest kernel I have around)
