Alan,
This rule works fine with the 2.6.11.10 kernel from 2005-06-16, but not
with the later ones. This may actually point at a version breach, and
thereby at the solution: I should build a 2.6.11.10 kernel with
ehci_hcd disabled (4). I'll report on this detour, too.
See this posting:
http://www.ussg.iu.edu/hypermail/linux/kernel/0505.2/1368.html
2.6.12 kernels require udev-058 or above. No doubt the problem you see is
the same as the one I fixed for the Fedora version.
Debian has released udev version 068 for its stable release. The palm
sync now works flawlessly with uhci_hcd on a 2.6.12.4 kernel. Thank you
very much for the pointer (and insisting on it).
In the meantime, I have received a message indicating that the USB 2.0
problem with IBM Thinkpads T40 may be a hardware problem on the host
side. The problem also seems to persist under Win XP and an ULD
(unidentified linux-dialect) on an Acronis True Image 8 CD: "USB 2.0
devices are simply not recognized under it"; even a BIOS upgrade didn't
help.
Perhaps I'll have to live with it. I can, since uhci now covers
everything I need for the moment. I'm pretty tight on schedule now, so
I don't have much time to test, but I will certainly try the "light"
patch asap.
