USB passthrough test reports in 7.5RC1
-
Can you create an issue asking for this detailed change to be made? We can create a test package with this change, so it won't impact other users

@olivierlambert created https://github.com/xcp-ng/xcp/issues/342 under xcp project. Thanks!

Thank you, perfect

OK, this is rather amusing. I've got USB passthrough working for my USB 1.0 device.

It is a gross hack. Apparently the xenopsd relies on the version number returned by the device to dictate the USB bus type of the controller it attaches to. I have no idea in what universe that makes sense.
The above only works for me as that is the only USB device attached to the HV. I guess I could make the code a little smarter by looking for a particular device ID and only over-riding the version then

A slightly less hacky work around for USB v1 passthrough based on the issue I created:

It may have side effects if the driver in the guest relies on the version number so caveat emptor.

Good Morning!
I'm new to xcp-ng, we have two Hyper-V hosts but we needed to add a usb token to a vm, so we decided to migrate a host to xcp-ng for testing, but my host is not giving me the option passthrough usb, my server is a dell T110 II, I have already checked the bios settings and apparently everything is fine.
I don't know what I could be doing wrong.
I'm using version 8.1 of xcp-ng and xcp-ng center 20.04.
I'm sorry if I posted the wrong call!
-
Hi. Does https://xcp-ng.org/docs/compute.html#usb-passthrough help in your situation?
-
@stormi
Good Morning!
When executing the command xe pusb-list I have no return.
-
@stormi Not at all sadly. The Device never passes though..

Let's give it another try to give my host its USB controller back and pass-through just the USB devices. In this case we're going for a virtual machine hosting common USB devices for home domotica.
The devices we want to pass-through:
- Future Technology Devices International, Ltd Bridge(I2C/SPI/UART/FIFO)
Which apparently is technical speak for a RFXtrx433XL USB 433.92MHz Transceiver - Prolific Technology, Inc. PL2303 Serial Port
Which apparently is technical speak for a ZiGate USB-TTL - Sigma Designs, Inc. Aeotec Z-Stick Gen5 (ZW090) - UZB
I'm using XCP-ng Center 20.04.00 to help me out and XCP-NG 8.1 on the host.
Let's start with a good old:
[12:56 vmhost ~]# xe pusb-list host-uuid=***** uuid ( RO) : 2ba8de5b-8fe1-0262-f741-35b4ed350ae0 path ( RO): 1-2 vendor-id ( RO): 067b vendor-desc ( RO): Prolific Technology, Inc. product-id ( RO): 2303 product-desc ( RO): PL2303 Serial Port serial ( RO): version ( RO): 1.10 description ( RO): Prolific Technology, Inc._PL2303 Serial Port uuid ( RO) : 08b23122-e01b-9ab2-e72d-185648ae19d7 path ( RO): 1-7 vendor-id ( RO): 0403 vendor-desc ( RO): Future Technology Devices International, Ltd product-id ( RO): 6015 product-desc ( RO): Bridge(I2C/SPI/UART/FIFO) serial ( RO): ******* version ( RO): 2.00 description ( RO): Future Technology Devices International, Ltd_Bridge(I2C/SPI/UART/FIFO)_DO2VQGDGOk, we have 2 devices already ready to be passthrough. Let's try to make the third one show up!
Using the follow commands and some reading I could identify the DENY rules in "/etc/xensource/usb-policy.conf", which prevent my Aeotec Z-Stick from showing.[13:06 vmhost ~]# /opt/xensource/libexec/usb_scan.py -d [13:06 vmhost ~]# cat /var/log/user.log | lessI've adjusted my "/etc/xensource/usb-policy.conf" to the following:

Using XCP-ng Center we can see these 3 devices and "Enable pass-through" for all of these 3 devices. After shutting down the VM, using properties we can attach all 3 USB-devices and start the VM again, but not before running the following command as was recommended:
xe vm-param-set uuid=**** platform:device-model=qemu-upstream-compatLet's start and monitor dmesg:

Oh and so far everything looked good, right? Everything got attached, the VM booted and the properties of the VM shows that all 3 devices are "Attached".
On the VM running ubuntu I get the following:
vm@vm:~$ lsusb -t /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/8p, 12M |__ Port 1: Dev 4, If 0, Class=Vendor Specific Class, Driver=pl2303, 12M |__ Port 2: Dev 3, If 0, Class=Human Interface Device, Driver=usbhid, 12M /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/6p, 480MMy USB 1.1 device (ZiGate) is present! The other 2 devices are USB2.0 and those are magically missing?! Why? How? What did I do wrong!? What can I try to make this work?
Ah well, time to pci-pass-through my USB controller into that device again, although I would have prefered USB-passthrough! I did also apply scottyXCPNG's workaround, but not allow my USB 2.0 devices to be passed into the VM with those applied.

I have good experience with WiBu Key dongles and a "Matrix USB-Key" (also license dongle) but couldn't get an Aladdin HASP working.
I can pass it through (it's visible and attached) but the VM doesn't show it in device manger (Windows 10 1909). I gave up for now and will probably use a network USB thingie from SEH - already have 2 of their devices running in different environments and they work flawlessly.
