Host is DELL T3610 running Windows 7 Pro 64 bit with 32 GB of RAM
Running VM Workstation 11.0.0 build-2505329 (Licensed)
Guest is Windows 7 Pro 64 Bit, 8 GB RAM
I have used VM Workstation for a long time. I use many USB devices. I simply plug them in and they attach to whichever virtual machine I have showing at that time. This has worked great for years. I attach my Samsung phone, Symbol Windows CE devices and SanDisk Cruzers - many different devices.
On the 20th of January, I upgraded my desktop from Workstation 10 to Workstation 11. I did not change any configuration, just uninstalled Workstation 10 and installed and started up Workstation 11 and upgraded the VM's to 11 and opened each VM.
After that, I was able to connect some of my USB devices (the external drives and thumb drives. At some point since then, I have lost the ability to connect any USB devices to my Guest systems.
USB is set to 2.0 compatibility in the Guest setup. I am not using any of my USB Hubs, but plugging a USB2 device into a USB2 port on the machine.
If I check the vm log file - it says failure to load drivers. Well, most of these things are generic drivers. How would the drivers have disappeared from the systems when they were on there before.
I can connect any of them to my host machine, but I cannot transfer any of them to my Guest machines. It makes the ding (like you have unplugged something) then it makes a 3 fast dings and just disappears. Nothing shows up in the device manager on the Guest. They all show up on the list of Removable devices and it will even stay checked that it is connected to the guest - but it won't actually show up (as a drive or connection) on the Guest.
Interestingly enough, if I connect them to the host, they show up in the device manager with the drivers correct. When I try to attach them to the Guest PC, they do not show up in the guest PC, but they also now show up as unknown devices in the Host PC! I have to unplug them and replug them to get them to show in the Host system again. This is a very strange situation and I'm certain their must be an easy fix.
I have removed the USB from each Guest, started them up, shut them down, added the USB back with 2.0 compatibility and still the same thing happens. I have even tried downgrading the Guest to 10.0 compatibility, but that made no difference either.
I have attached a log file where you can see that it does indeed recognize my android phone, san disk cruzer and symbol CE device. But you can also see that there is a driver error when I try to move it to the guest. I have no idea why... these are all generic drivers that have always worked before on theses guest.
This is a critical issue for me as I really need to backup my systems and synchronize data with some of these devices.
Any help would be greatly appreciated.
