I've made also another log and there is clearly a data0 before this data1. (I can put the whole log onto a ftp server if somebody wants to look at it. It is from insertion of the reader up to the fault.) > > I have not log here, which shows the first and second run.

It works under 2.4 and on the other computer under OpenBSD, but not anymore under 2.6. And why does this happen not inside a program run, but only in between? I don't think the hardware does notice this, if the UHCI driver does nothing change. It works again, if I unplug and replug the device. So probably something has changed in the open/close handling in UHCI, which annoys the host controller. > I don't know the answer.
