Hi,
I'm facing a problem if I connect Officejet 470H printer. I get Unidentified
USB device dialog on the screen. If I connect HP deskjet 6122 printer then I
dont get such error. I tried to build a new image by changing some code in
LPT.C but invain. I tried to debug platform builder code and I found that
for Deskjet 6122 number of interfaces are 1 and for H470 number of interfaces
are 3. LoadDeviceDriver function of
WINCE50\PUBLIC\COMMON\OAK\DRIVERS\USB\USBD\usbd.cpp code is returning false
value for H470. So can you guide me in this matter?
