I'm sorry for no responding at once.
I tried to install tracing tools , Dbgview.exe had only few info, however, another tools like traceview.exe from WDK could not be installed, so i get on traces now.
But I build another environment using win10 32bit with virt-viewer 5.0/6.0 and UsbDk 1.0.17/1.0.19, both of them aborted. because of the complex compilation process on windows, i can never debug the code.
So i wish you can investigate the BUG, thanks!

Firstly, I installed UsbDk 1.0.19 and VirtViewer 6.0.256 , then i tried UsbDk 1.0.17 and VirtViewer 5.0.256 .
and i tried Sandisk and Kingston usb device , all of these aborted .But i never install libusb additionally , only find libusb-1.0.dll in virtviewer\bin\ .is that enough ? it's right with windows 64bit when only installing UsbDk and VirtViewer .
Yes this is enough.
There are two issues that we need to investigate in order to resolve this:
1. What is the error occuring in the first place
2. Which component is not handling this failure correctly
For 1 enabling UsbDk tracing can give us a bigger picture on what's causing this error, please refer to the following link for instructions on tracing UsbDk:
For 2 It could be the usbredir (https://cgit.freedesktop.org/spice/usbredir) component failing to handle libusb failures. I am not that familiar with the usbredir code,
but inserting few debug prints in the main loop should give a good idea where this bug lies.
Please do send traces back so we can further investigate the issue =)

I tested some VERSION of virt-viewer、UsbDk and spice-server , but it allways aborted .
I got this when --debug "libusb: error [windows_transfer_callvack] detected I/O error 1627: [1627] 执行期间，函数出了问题"Which version of libusb, UsbDK are you using? Can you reproduce this with other usb devices?
Can you help me for this ? Thanks .
