I am using Lothar's isp1362-hcd.c driver on a 2.6.16 kernel and a homebrew power pc board. I got the driver to semi work and it is talking with the chip, best I can tell. I am trying to get a simple usb flash key to work... and so far, It looks like the start address is going out and I think an answer is coming back, but for some reason, the ptd is being removed and not accessed.. I think the ATL interrupt never happens, so it doesn't really read the PTD that came in.. the second SOF interrupt just seems to delete it... thus my ultimate error is the hub time out. A trace is included below and if anyone has a clue to what is going wrong I would welcome any hints or possible solutions. the usb stuff is a bit new to me.. but I am slowly starting to understand it.. Bob
