Hi, I have a problem since the upgrade on Parallels 11. I made the test on two separate MacBook. I use Tuxera, and I also try with Paragon (but I don't if there is a link). So, when I start Parallels, even it's only the main application (no OS guest), my mac doesn't connect my hard drive to my mac. I can start my W7 virtual machine, then click on device, select my hard drive, which is well connected to the virtual machine. But if I deconnect it from W7, it doesn't appear on my mac. I disconnect my hard drive, close the virtual machine, close the main application Parallels and then connect my hard drive, it is well connected to my mac. I made a lot of test, modified the options (connect to my mac, to virtual machine or ask when plugging a USB device), but it is always the same thing. I uninstall Parallels 11 and try on Parallels 10 and it works well. Same test with Parallels 11 on an other mac, same problem. I think it's a bug, maybe link to Paragon/Tuxera. But I'm not sure because there is the same problem with a FAT32 USB stick. MacBook Pro mi-2014 with El Capitan. Thank's for your help.
