Subject: [PATCH] usb-redir: Ensure our peer has the necessary caps when
|
|
redirecting to XHCI
|
|
|
|
In order for redirection to work properly when redirecting to an emulated
|
|
XHCI controller, the usb-redir-host must support both
|
|
usb_redir_cap_ep_info_max_packet_size and usb_redir_cap_64bits_ids,
|
|
reject any devices redirected to an XHCI controller when these are not
|
|
supported.
