Hi Peter,
It's possible that this is more of a problem of your thumb drive than of the USB stack.
Indeed. Especially if the drive is actually a high speed device then frequently it will not work perfectly running at full speed.
In the meantime I've tested 1 USB keyboard and 8 storage devices from different vendors (2 card readers, 1 M-Systems uDOC, 5 thumb drives, 1 of which is an ancient USB 1.1 only). None worked.
An interesting data point would be for you to attach the drive when the system is running Linux, *without* the ehci_hcd driver loaded, only ohci_hcd.
Tried that with the 1st card reader which had made me write the original message. Works with OHCI-only in Linux.
Cheers, Jens

I'll try again - might have messed up something when integrating to the public tree :-(
keyboard won't work on OHCI yet - the interrupt transfer model needs rework before I'll enable it for the non-UHCI controllers.
Thanks, Patrick
