Hi,

Seems like a usbclerk problem ==> not removing the WinUSB driver upon 
client distconnect
- What are the versions of usbclerk, virt-viewer ?
----------------------------------------------------------------------
virt-viewer 0.5.7,  the version of usbclerk  not clear (cody provides)
----------------------------------------------------------------------
- Anything interesting in usbclerk's log (try at 
c:\windows\temp\usbclerk.log) ?

****(**1. teclast usb device recognize as an unknown "universal serial bus device", but kinston is correctly recognize as itself
            2.oem22.inf is similar to inf i've posted except the section "strings")
----------------------------------------------------------------------
- Older versions of usbclerk did not remove the driver upon client 
disconnect, can
   you try un-redirect the usb device (from the remote-viewer menu) 
before disconnecting the client ?
----------------------------------------------------------------------
already tried, all turn out to the same result
