| #7462 | fixed | USB device not available in a guest using more than 1 CPU | ||
| Description |
If I configure my guest OS to use more than 1 CPU then I can't use my USB device. I have a iMac model iMac11,1 with a Intel Core i7 (4 CPU with 2 threads each) The USB device is a CCID smart card reader with vID=0x08E6 and pID=0x3437. The device works great if the guest uses only 1 CPU. But I get errors if I configure VirtualBox to use 2 or more CPU for the guest. The errors reported by the kernel are: [ 56.092448] usb 2-1: new full speed USB device using ohci_hcd and address 2 [ 62.637182] atkbd.c: Spurious NAK on isa0060/serio0. Some program might be trying access hardware directly. [ 71.249524] usb 2-1: device descriptor read/64, error -110 [ 86.512425] usb 2-1: device descriptor read/64, error -110 [ 86.809503] usb 2-1: new full speed USB device using ohci_hcd and address 3 [ 101.976574] usb 2-1: device descriptor read/64, error -110 [ 117.240584] usb 2-1: device descriptor read/64, error -110 [ 117.536353] usb 2-1: new full speed USB device using ohci_hcd and address 4 [ 122.578952] usb 2-1: device descriptor read/8, error -110 [ 127.698748] usb 2-1: device descriptor read/8, error -110 [ 127.996433] usb 2-1: new full speed USB device using ohci_hcd and address 5 [ 133.042903] usb 2-1: device descriptor read/8, error -110 [ 138.161658] usb 2-1: device descriptor read/8, error -110 [ 138.264556] hub 2-0:1.0: unable to enumerate USB device on port 1 and the lsusb command line tools is locked until the kernel gives up enumerating the device. I have the problem with Debian testing/squeeze and also with Ubuntu 10.04. It is quiet easy to reproduce. I also tried with Windows 7 and the device is visible with 1 CPU but not with a 2 CPU guest. So the problem is not limited to a Linux guest or the Linux kernel. Since the problem is not linked to the guest OS it must be in VirtualBox itself. |

| #14669 | obsolete | No insulation on NAT | ||
| Description |
I'm using a windows 8.1 guest OS and a windows 7 as Host machine. When I setup a NAT network, using the Intel PRO (Desktop) adapter, the guest OS connects straight to the Host network, as a full member of the Host's network without any kind of insulation. |

| #15257 | fixed | Auto-resize broken - Win10 Host & Guest | ||
| Description |
I have a problem where my windowed guest will revert to 800x600 or a similar default resolution on the primary monitor after returning to my host after the screensaver comes on. The secondary screen stays as is. The guest mouse is also becomes out of sync with the host. If I move the host mouse to the far right of the primary screen the guest will be closer to the middle. If I move the mouse to the left each pointer will be much closer together but still not in tune. I normally work in maximized windowed mode. By that I mean the guest will be within a VirtualBox window but that will be maximized take up the most amount of space without hiding my host's taskbar. This problem is becoming a show stopper. The only solution so far has been to restart the host entirely. It is starting to happen once or twice a day (I use VBox alot). Things I have tried:
