[PULL 12/17] usbredir: avoid queuing hello packet on snapshot restore

Posted by Gerd Hoffmann 3 years, 8 months ago

From: Joelle van Dyne <j@getutm.app>

When launching QEMU with "-loadvm", usbredir_create_parser() should avoid
setting up the hello packet (just as with "-incoming". On the latest version
of libusbredir, usbredirparser_unserialize() will return error if the parser
is not "pristine."
