Hello
<BR>
&nbsp;
<BR>
I have traced the hang on the hpusbscsi module to the loop that calls &quot;schedule&quot;
<BR>
in hpusbscsi_scsi_queuecommand. It hangs here:
<BR>
&nbsp;
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;while (hpusbscsi-&gt;state != HP_STATE_FREE)
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;schedule();
<BR>
&nbsp;
<BR>
As far as I can see the state flag should be changed to HP_STATE_FREE by
<BR>
control_interrupt_callback before sending the scsi command, but it is not.
<BR>
&nbsp;
<BR>
I hope it is useful just like this.
<BR>
&nbsp;
<BR>
Regards
<BR>
<P><PRE>
