Re: USB redirection: "LIBUSB_ERROR_NOT_SUPPORTED"

[Yuri Benditovich <yuri.benditovich@xxxxxxxxxx>]

I see the virt-viewer 8.0 uses only WinUSB as it includes libusb 1.0.22 (which uses dynamic configuration of backend with WinUSB as default) and spice-gtk 0.35 (which does not configure libusb to use UsbDk).

I suggest to try virt-viewer 7.0 instead, then libusb will work with UsbDk.

Best regards,

Yuri

Hi Yuri

Oh, it can see i left that out, but here it is:
- I installed UsbDk on my Win7 x64 client PC (where remote viewer is running)

- Remote viewer version: 8.0-256

- libusb-1.0.dll version: 1.0.22.11312 (07-08-18)

- Log-file attached

Hi Brian,

Which backend you use on your Spice Client machine, UsbDk or WinUsb?

What is the version of remote-viewer and the version of libusb-1.0.dll (it should be in the same directory when remote-viewer.exe)

I'd also suggest to make a debug log (usually "remote-viewer ... --spice-debug > log.txt 2>&1") and provide the log.

Thanks,

Yuri

Hi Spice-devs

I'm trying to get some USB headsets to work on a VM (Win10 x64) using spice USB redirection, but I get the error "LIBUSB_ERROR_NOT_SUPPORTED".

Is it a misconfiguration or is the device really not supported?

I've added a ich9 USB controller on the VM:

<controller type='usb' index='0' model='ich9-ehci1'/>

<controller type='usb' index='0' model='ich9-uhci1'>
  <master startport='0'/>
</controller>

<controller type='usb' index='0' model='ich9-uhci2'>
  <master startport='2'/>
</controller>

On my VM:

On my W7 box I have these controller:

This is my options in spice:

And the error:

Can I do further action to track down the problem?
