USB license on Hyper-V guest

Post by CRM User » Mon Jul 23, 2018 8:10 pm

I am running Asterisk in a guest OS on Microsoft Hyper-V and I chose to use the license on USB key activation option. How do I connect the USB key to the guest?

I've used VMware before and I know it's easy to pass through a USB device with VMware, but Microsoft has chosen to make this painful. Is there a workaround or do I need to change activation types? (you mentioned I could return the USB keys if I wanted to change)

In order to connect a USB device to a Hyper-V guest you need to use a USB over IP solution. This means you plug the USB device into a real (physical) device(possibly even the Hyper-V host) and then attach it to the guest over a network (IP) connection.

For example, there are software packages which will share a USB device over an IP connection:

Example packages include: Note that the free solution may already be rolled into your Linux kernel (so you don't need to install anything on the guest).

There are also commercial hardware products which will share a USB device over an IP connection:

Example devices include: Some clients have used a Raspberry Pi to create a USB device server on their network for USB keys and other devices shared across their data center.

We try to avoid endorsing third party products unless we continually test their product with our dongles (which we do not at this time), but we have been told by customers that they have had success with a couple of the software packages above.

Telium has certified the CoolGear USB-NET-4A USB over IP hub for users who wish to plug (license) USB dongles into a stand-alone network device. This enables the PBX virtual machine to move across multiple hypervisors / hosts, with the USB Dongle visible to the guest as it moves. This device also makes it possible for Hyper-V users to pass-through USB devices to any guest. (It does not make it possible for multiple virtual machines to share a single dongle). The IP of the IP hub must be on the same subnet as your VM guest.

The USB-NET-4A is available directly from CoolGear here: https://www.coolgear.com/product/usb-2- ... ip-network

As this product is not purchased from Telium we do not include any support for this device. We cannot answer any questions about the USB-NET-4A functionality, compatibility, drivers, etc. (Please direct those questions to your retailer of choice). If you would like Telium to support your USB-NET-4A device, including configuration, setup, connectivity to the guest, etc. then you would have to purchase 2 hours of support from Telium.

Note: Telium is succesfully using the USB-NET-4A in its quality assurance lab, so we can confirm the product works well. As well, Telium will continue to use and certify the USB-NET-4A until otherwise posted.
