Dear linux-dvb developers, 
owning an HP rebranded Hauppauge Express Card shipped with several mid-high end HP laptops I would like to give you some support in further improving cx23885 driver for it to support those tuners.

here are my card specs: 
HP Hauppauge WinTv 885
model 77001 rev d4c0 (Model 77xxx Analog/ATSC Hybrid, Xc3028)
tuner: Xceive xc3028 http://www.xceive.com/technology_XC3028.htm
audio tuner: stereo cx23885
decoder: cx23885 http://www.conexant.com/products/entry.jsp?id=393

- insmod cx23885 manages to create a /dev/dvb device folder only if arguments card=3 or card=4 are supplied

- despite the card being recognized with such arguments I cannot manage to use Kaffeine DVB support as although kaffeine -w recognises the card, it cannot scan for any available channels ('scan on' dropdown menu is empty, clicking 'Start Scan' button does not list anything)

- also with Klear, provided a channel.conf, the program cannot  tune to any channel and outputs the same error as the scan command from dvb-utils: 
"WARNING: frontend type (ATSC) is not compatible with requested tuning type (OFDM) ERROR: initial tuning failed"
 
 - the device is not hot-plug recognized, I had to reboot before the system can actually recognize it (however both express card specs and windows support plung&play).

Any other help I could provide you with debugging/testing these cards I would be pleased to, just ask.
Thank you very very much for pioneering dvb video support for gnu/linux, I really appreciate your efforts.

here is my lspci -vvv -nn -xxxx output
