Title:
trace_usb_port_attach prints junk data
Status in QEMU:
In Progress
Bug description:
Running qemu with tracing (-D ~/qemu_trace -d trace:\*) will result in
a trace file with unprintable characters.
example: usb_port_attach bus 0, port 1, devspeed <90>l<DB>.<D8>U,
portspeed full+high
The problem is in hw/usb/bus.c usb_mask_to_str. If speedmask doesn't
match any of the defined speed nothing is written to *dest and
uninitialized data is printed to the log.
This happens with a real usb device that is forwarded into the
machine.
My qemu version is 2.6.0 but it looks like the problem exists in
latest git also.
