ippusbxd 1.33 released!

[Till Kamppeter <till.kamppeter@gmail.com>]

Hi,

I have released ippusbxd 1.33 now, with the following fixes:

Vast improvements in the communication code contributed by David Valleau 
from Google (Chrome OS printing guru):

- Changed USB code to hold all IPP-over-USB interfaces as long as
  ippusbxd is running
- Made the communication bi-directional with polling
- Changed unregister_service_thread() to deallocate removed thread
  parameters
- Fixes for high-DPI web scanning (transferring large amounts of data)
- Fixed spurious recv and USB timeout errors

Can you please upload this version into Debian so that it syncs into Ubuntu?

   Till
