Hi I am using the ISP1562 on my PCI and using the OHCI code. I am able to reset and initialize the controller as i am able to see the reset signal and High speed chirp signal on the bus but there is no data on the bus. It shows the invalid packet on with all 0xFF at the first time i connect the mass storage device what could be the problem ? 
How i have to map the PCI memory ? 
I though that it could be the invalid memory access as i am taking the gohci and hcca structure by just taking it as an array and the controller HcHcca registers are unable to access that location it 0x7ffa0000 in my case where my PCI memor is mapped at 0x80000000 

Need some help 
Regards
