[Qemu-devel] hw/usb/host-libusb.c:1254:217: err or: ‘LIBUSB_LOG_LEVEL_WARNING’ undeclared here (not in a function)

[Michael Tokarev]

The error in $subject is spewed when trying to compile current
qemu code on my debian wheezy system.

/usr/include/libusb-1.0/libusb.h does not define any LIBUSB_LOG_LEVEL*
constants.  libusb-1.0-0 on my system is of version 1.0.11.

Should we define some minimum libusb-1.0 version requiriment, or
conditionally compile the 'loglevel' property?  Which minimum
version is needed?

Thanks,
