Ubuntu: what are the proper values for usb device in virtual box



Question:

I have various windows programs running in virtual boxes. I have a StingRay scope which previously ran in xp with the following parameters usb parameters

The product is DS1M12A, but I don't know how I got the details the first time around. Now I can part of the details via lsusb -v which gives

The only thing which is obvious is the Vendor ID and the Product ID. Where I previously picked up all the other information is a mystery.

I tried to put in empty strings for Revision, Manufacturer, Product and Serial No. but it didn't help. When I tried to have win7 discover the scope, it failed to see anything.

Again, this used to work for my xp virtual box but it has stopped working. In the meantime I switched versions of Ubuntu as well as switched the underlying computer from dual core to quad core. All the rest of my usb devices continued to work OK.

Thanks, Ilan


Solution:1

We can list all entries needed for creating an USB filter with the following command:

VBoxManage list usbhost  

This will give us an output similar to the one below for all devices recognized in the host:

UUID:               123400c1-fc2c-44b8-202f-e5c80c133027  VendorId:           0x03f0 (03F0)  ProductId:          0xa407 (A407)  Revision:           3.33 (0333)  Port:               1  USB version/speed:  2/Full  Manufacturer:       HP  Product:            HP Link-5 micro dongle  Address:            sysfs:/sys/devices/pci0000:00/0000:00:10.0/usb6/6-2//device:/dev/vboxusb/006/002  Current State:      Busy  

For creating an USB filter to always capture a USB-device when running a virtual machine we can select from any one of these entries.

We can e.g. just fill in theVendorID to let the virtual machine capture all devices from this vendor. In case we additionally give the ProductID is becomes less likely we have more than one such device attached, but stillm giving a UUID or the Serial in addition helps to only capture this single known device.

Note that most but still not all devices are supported by Virtual Box or the guest OS. Some devices may even lead to a boot failure of the guest when defined as a filter. We can not use filters on such devices then. Some USB2.0-devices will not work on an USB3.0 port.
