It is a hack to get > past the initialization. PAS: In my case I had to set the dma masks in order to "trick" OHCI into thinking it is using dma. The are statements in hcd.c of the type "if (dma_mask) ..." So if it is not set, functions like hcd_submit_urb() don't seem to fill the setup_dma / transfer_dma fields that OHCI expects and translates into data that is later needed by the isp driver. ok.

I think not hardware related because the 16bit register look still ok... Konsti PAS: Doesn't look like anything I ran into before. I'd suggest, dump the registers during during driver init at some point. If the registers are printed out find even only once, you don't have to worry about it being a LE/BE issue. If you are getting this far into the driver, I doubt this would be the issue. Instead, it almost looks more like you are reading back the address register somehow, as all 32 bit data regs contain their address value. -- GPG KeyID EF62FCEF Fingerprint: 13C9 B16B 9844 EC15 CC2E A080 1E69 3FDA EF62 FCEF ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
