[Info-vax] Processes hang on USB-access

[Volker Halle]

Jouk,

the SDA USB extension won't probably help. It's mostly about all the USB related configuration data structures.

If the device would be waiting for an interrupt, the Device Status would have 'int,tim' set.

You could turn on IO tracing (see SDA> IO), but all you probably would get is the last IO started on the USB disk and not WHY it does not complete.

The current IRP is pointed to by the UCB, try to find out, what it is supposed to do and why it's not completing.

Volker.
