Any ideas on improving this? If the trans_usbg code can detect the host device is gone it should mark client->status as Disconnected then wake up all pending requests (something like p9_conn_cancel in trans_fd.c) Sorry I haven't found time to test/review either; I'd still be interested in running this in qemu for non-reg over using a real device so need to spend a few minutes figuring out the exact command line required.. I'll try to find some time this weekend -- Dominique
