I don't see how it could make any difference, since the log did not show any suspends at all, auto or otherwise (except for the OHCI-internal suspend before the Treo was connected). > However, as it seems to, it is important that > you know of it.

Maybe Dirk should try using 2.6.20-rc5 and see if it makes any difference. Also try attaching the Treo to a different computer.
