When I plug in my IRiver-795 or iRiver-395T MediaCenter just hangs!.  I've tried redetecting the device (which removes everything in Media Center) and then plug in the iRiver but no dice.

[Matt]

Could you post a full log after the hang? (Help > Configure Debug Logging...)

Some of the iRiver device drivers don't deal well with threading.  I thought we had the issue side-stepped, but apparently not in all cases.

Thanks for helping.

Here's what I got.  Started MC and reset the log and then pluged in my iRiver 795.  Hang and then I looked at the log:

I think you just need to add an entry to the PDT.

Try editing MC\Data\Default Resources\PDT.xml

Find this entry:
   <Device>
      <Type>0</Type>
      <Vendor>iRiver</Vendor>
      <Name>iFP-780T;iRiver iFP-395T;iFP-880T;iRiver IFP-880;iRiver IFP-890T;iFP-990T</Name>
      <PlaylistBasePath>ROOT</PlaylistBasePath>
      <RootBasePath>\</RootBasePath>
      <AlwaysPumpCOMMessages>1</AlwaysPumpCOMMessages>
   </Device>

Add "iRiver IFP-795T" (and other iRiver devices you're using) to the name list.  The key is that "AlwaysPumpCOMMessages" thing.  iRiver drivers don't handle threading like they should, but this works around it.

Let us know.  If it fixes it, we'll roll the changes into the next build for everyone.

Thanks.

Great!! Seems to have worked.  Although the only other thing is that there is no eject for the handheld in MC.  And I cann't "safely eject" via windows because MC has a lock on it.  Is this some other alteration to the PDT.xml file?
