| Summary | 0011462: Empty Drive letters can delay MMW close. | ||||

@Peke, I've seen the logs from ticket YPE-656664 now. And it seems that it was caused by UPnP as the last line in the log is Going to call UPnP.dll :: DoneUPnP Can you share the details why you think it is "Empty Drive letters" delay and eleborate? I know you had a remote session with the user, but I don't know what were the results. |

@Ludek Like you I analyzed logs and noticed that DoneUPnP was executed So we went to disable media Sharing with MMW and Tried to Close which didn't changed anything. User pointed that after some timeout MMW closes which pointed to the fact that there was some background jobs still not finishing up. On opening My computer I noticed that Card reader Assigned drive letters didn't show NO Card inserted (I had such issue with my old Card Reader that needed own driver to show inserted state and after upgrade to Win 7 driver was not available so I found third party app that will set empty flag for card reader letters and hide them until actual Card is inserted). Only other way to eliminate MMW trying to access Card Reader/drive letters and check for content was to set Ignore those drive letters from MMW and test. Result was instant MMW close. After ending session I compared results with my new card reader (driverless) and noticed that it uses windows native driver for removable storage (Floppy Class) instead of USB Storage like old one which tell MMW not to scan drive access constantly. I filed this bug so that we can investigate if there is a way to determine even drive letter exist and appear accessible MMW read flag that drive with No Media ANd react only on Change like we do with CD-Roms eg. removable Drives with "NO MEDIA" should be ignored.
