Well thanks for trying, but my system isn't like yours (apparently). When I go to Start, Programs, Dell Printers, Dell Photo AIO Printer 942, I get a submenu that includes Activate Memory Card Manager. When I double click on that, I just get athe same window as I get when I insert a Memory Key, and it says Failed to locate supported file types or there are no photos found on this device. The only option is to close this window. Right clicking does nothing. Going back to the start path submenu, if I right click, I can get properties, but that doesn't offer any options regarding display or operation.
By browsing to the program files, in the Dell Printer folder, I find a memcard.exe and a memcard.hlp. When I launch memcard.exe it opens that same window (like when I insert a USB Memeory Key). I notice that the memcard help file says " Memory Card Manager launches when a Mass Storage Device, or memory card, is loaded in the card reader on your printer." Notice, it is supposed to just activate when the printer card reader is loaded. Well, that's not the way it's working, it activates when ANY usb port is used, and I can't figure out a way to change it. I even tried Dell tech support, What a waste of time. I got sent to 3 different technicians, with the last one telling me it was beyond her technical expertise. I wasted about 3 hours with that approach.
I came to the forum today to find out exactly what purpose memcard.exe and dlbubmgr.exe served. I found this post about the problem with putting in a USB key...realized I hadn't tried mine since I installed the new printer. Tried it, got the same error mentioned in previous posts. Also tried to find a way to change the setting to keep the program from running and got the same thing.
I guess I'll just try to disable memcard with Startup Inspector. Anyone know what purpose dlbubmgr.exe serves? Do I need it?
