usb keys disappearing

Hello,
I have the following issue with usb redirector: a shared usb key disappears after some days of being shared. These are the details:
 
- A usb key is shared using usb over network server. The machine where it is shared is a Windows Server 2019.
- The usb key is properly connected to other client machine which has the usb over network client installed. This client machine is a Windows Server 2012 R2.
- This arrangement work properly for around 10 days.
- After around 10 days the usb key is no longer available on the client machine. The client reports 'no devices available' on the server.
- The server reports 'unplugged, will be shared when plugged'.
 
At this point the following also occurs:
- Windows device manager on the server machine reports an usb device with problems: 'unknown usb device (device descriptor request failed).
- The usb key is no longer available locally, even if the key is no longer shared or the usb-over-network service is stopped.
- A reboot of the server does not help, the usb key is still unavailable locally after a reboot. Even disabling the usb-over-network service so it does not start automatically after reboot does not help. The usb key is still unavailable locally after rebooting.
- It is necessary to physically change the usb key from usb port in order to have it available locally and the be able to share it again.
 
I hope you can help me with this issue,
Regards.

Hi,
 
In my opinion you have a problem with device on the hw level.  
Just unshare your device in USB over Network (server) and work with it for around 10 days.
