Hi, guys:
I'm trying porting hc_isp116x ( version Tango ) to my PXA255
platform ( armv5tel ,linux-2.4.19). It seems works well with
usb-storage, but I cannot get it work on my quickcam and the
iso-transfer part doesn't work, I tried to dump the buffer information
in ATL Buffer & ITL Buffer and it seems that when I write PTD
relevent to ISO transaction the ITLBufferFull in HcBufferStatus will
not setup. Can anyone find some solution for this?
By the way, I found that the Tango version driver does some
extra work with ITL Buffer, it will write 0 to all those empty space
in the ITL Buffer, which is unnecessory and will influence its
performance.
