Since the problem is not linked to the guest OS it must be in VirtualBox itself. So the problem is not limited to a Linux guest or the Linux kernel. I also tried with Windows 7 and the device is visible with 1 CPU but not with a 2 CPU guest. I have the problem with Debian testing/squeeze and also with Ubuntu 10.04. hub 2-0:1.0: unable to enumerate USB device on port 1Īnd the lsusb command line tools is locked until the kernel gives up enumerating the device. usb 2-1: new full speed USB device using ohci_hcd and address 5 usb 2-1: device descriptor read/8, error -110 usb 2-1: new full speed USB device using ohci_hcd and address 4 usb 2-1: new full speed USB device using ohci_hcd and address 3 usb 2-1: device descriptor read/64, error -110 Some program might be trying access hardware directly. atkbd.c: Spurious NAK on isa0060/serio0. usb 2-1: new full speed USB device using ohci_hcd and address 2 But I get errors if I configure VirtualBox to use 2 or more CPU for the guest.
