答复: The second client cannot redirect USB

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Thanks for your reply. But If I want to support multiple channels for USB redirection when multiple clients connect to a same VM,  do you know which project includes the code about USB channels ?   Spice ? or QEMU?

 

Thanks and Regards,

Xuefeng

Hello,

 

   When I used two client to connect to a same one VM by spice with setting SPICE_DEBUG_ALLOW_MC=1, the two clients worked, and the first client could redirect USB. However, the second client could not redirect USB device, It shows like the picture:

 

Im sure that therere enough channels for USB redirection.

 

Is this a problem? Or Is there any way that could resolve the second clients USB redirection problem?

 

Thanks and Regards,

Currently all character device channels (including USB one) do not support multiple channels, so the first client takes them all.
