Subject: [PATCH] usbredir: avoid queuing hello packet on snapshot restore
Date: Fri,  6 May 2022 21:18:50 -0700	[thread overview]
Message-ID: <20220507041850.98716-1-j@getutm.app> (raw)

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."
