All USB flash drives, mouse, keyboard succcesfully connects from host to guest via Virtualbox. But I have a hardware VPN key (AMICON VPNLDR 1.5 device) that connects to Windows XP as host normally, succesfully connects to guest via any virtualbox on Ubuntu Jaunty, but I can't connect it on Debian Lenny (that is installed on server, Ubuntu - on client computers). When I insert this device, in messages I see: {{{ Oct 9 16:00:57 beam kernel: [103940.864726] usb 4-2: new full speed USB device using ohci_hcd and address 4 Oct 9 16:00:58 beam kernel: [103941.077039] usb 4-2: New USB device found, idVendor=a420, idProduct=5420 Oct 9 16:00:58 beam kernel: [103941.077042] usb 4-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Oct 9 16:00:58 beam kernel: [103941.077045] usb 4-2: Product: VPNLDR 1.5 Oct 9 16:00:58 beam kernel: [103941.077047] usb 4-2: Manufacturer: AMICON Oct 9 16:00:58 beam kernel: [103941.077133] usb 4-2: configuration #1 chosen from 1 choice }}} When I start the guest and try connect this device to it, the Virtualbox interface hang to about 8-10 seconds and after that I see the error: {{{ Failed to attach the USB device AMICON VPNLDR 1.5 [0100] to the virtual machine oldlinux_image.

I try to create filters for this device, but it isn't helps. This device is a hardware VPN key for the Sberbank Client Bank software, that is very popular in Russia and many of organisation use it. How can I fix the problem? Which folders, files or processes is depend on virtualbox mount process?",defect,closed,USB,VirtualBox 3.0.8,worksforme,amicon vpn sberbank,,Windows,Linux
