I just opened a HP wifi driven printer and found an Marvell Avastar 88W8782 Wifi Module with 12 Pin connector to the main board. From googling I found that this is a USB interface driven module but I cannot find a datasheet with any pinout info. This module is suppose to have a Uart and also a spi bus. Does anyone has any idea on how to use this module?
Only datasheet I am end up with is enter link description here

Found the pinout on Aliexpress:
Some links that may help you:
See Download section in the following link, download Application notes zip: http://www.embeddedworks.net/wlan493.html
check out the pdf file named 88MC200_Hardware_Design_Guide (MV-S302321-00) inside the zip file. (page 15) It talks about interfacing a microcontroller to this WiFi module.

\$\begingroup\$ That seems to be a different module from the one that the O.P. has got. I would imagine that firmware, command protocol, behavior are different. Overall, trying to reuse a salvaged module like the one in the O.P. is a wrong use of one's time. \$\endgroup\$ Feb 17, 2016 at 3:49

\$\begingroup\$ The model number is the same as the one O.P. has got, I only tried to find anything related since the only datasheet doesn't give much of information. I also agree with you, there are open source modules that can be used instead of this one. I would recommend ESP8266 for example. \$\endgroup\$– IkbelFeb 17, 2016 at 12:15
