Over the weekend, I updated to PD10.0.2. Yesterday when I was working I ran into numerous issues with attached USB devices. Serial port adapters: It did not matter whether the device was Prolific chipset or FTDI chipset, communications would get corrupted or the device would simply become unresponsive. SOLUTION: revert to 10.0.0 and devices would work properly. ST-Micro STLINK2: Simply would get random disconnects to target. SOLUTION: revert to 10.0.0 and devices would work properly. The serial devices exhibited the symptoms in both Win7,SP1 and Win8.1 VMs. Reboots of VMs would sometimes fix the issues for as while. Bottom line, PD10.0.2 has somehow messed up at least some USB devices that worked without any issue in PD10.0.0. System: Late 2013 3.2GHz iMac, 24 GB RAM, OSX10.9.4
Hi, I installed PD10.0.2 about a week ago. I am using many USB devices from FTDI and others simultaneously without any problems. regards spachner
Well, after a week of going back to PD10.0.0, I have not encountered the issues with USB device disconnects that I had with 10.0.2. However, there is a general USB issue with PD10. With PD10, VMs no longer automatically connect to USB devices that were assigned to "use with this VM". The item in the Parallels menu list is checked, but it does not actually attach to the VM. An example, I have a software authorization USB dongle that I used to keep plugged in all the time. In PD9, I would be able to open a Win8.1 VM and then open the app and all was good. Now under PD10, doing the same thing I get a dongle not found message. I look at the Parallels devices menu and it shows the dongle as attached, but in the Windows device manager it is nowhere to be found. I have to physically unplug the dongle, and then plug it back in to be recognized. This happens with a couple other devices that were assigned to "use with this VM".
Yes, this is right. I also have to assign my USB devices mostly again to my VM after restarting the VM. Though, I advices PD to retain them. This USB retain mechanism was not reliable before PD10 and is not with PD10. But, I have simply have to assign them from OS X to VM, I do not need to physically unplug them. So, it is can be done by mouse - and yes, it is annoying. regards spachner
