USB Redirection doesn't work with virt-viewer 8.0

Hi,

I have checked the Windows version of virt-viewer 8.0 with both oVirt and virt-manager (after installing USBDk). In both versions you can see the USB devices, but with version 8.0 it gives a random minus error while in version 7.0 it works.

Thanks

added virt-viewer win32 labels

Hi, I know that you have posted this log but if you can attach a full log of the problem happening, that would be great.

Well, it took me a bit of time to get used to CMD stuff ;)

Anyway, full log (stdout and stderr) is enclosed.

out.log

@victor, do your need more info or is the log from Hetz adequate?
I've tried to use USB redirection on both Win7 and Win10 with and without usbDK installed. Works find with remote viewer 7.

Yuri Benditovich took a look at my log and had the following comments, I don't know if they would be of any help, but here they are:

"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 UsbD"

and

"I see in your case libusb DLL uses WinUSB (I think it is typically available out of the box). And it looks like (from the logs) there is some missing API in WinUSB path that makes the redirection to fail. "

changed milestone to %v0.39

Hi, sorry huge delay. Easy to reproduce, on nested client (Win 10 on Fedora 31) I got error -5 and on bare metal Windows 10 I got error -12, this with virt-viewer 8.0. virt-viewer 7.0 worked fine.

Let's see if we can get this fixed by soon and get a new release of virt-viewer out.

I reproduce the problem with virt-viewer 8.0 for win_x86 and win_x64. The same issues was also reported here: https://bugzilla.redhat.com/show_bug.cgi?id=1701931

Should be simple to fix, just replace the libusb.dll with one from 7.0 package

Is it a bug in the libusb or in our packaging or in our code with new libusb.. ?

If this helps, then this is the bug in packaging of virt-viewer

removed milestone %v0.39
