Hello,

I'm about to rework our driver to work under Windows 7 64bit. While other
requests to our devices are working well, the isochronous request
REQUEST_ISOCH_ATTACH_BUFFERS fails in the completion routine with
STATUS_INVALID_PARAMETER. Unfortunately I don't get any information which
parameter is wrong.

The driver works well under Windows 7 32bit but I can not see a real
difference in the driver own logs compared to the logs under 64bit Windows
7.

(I read this posting: http://www.osronline.com/ShowThread.cfm?link=166737
and started the comand script, but the log file with the OHCI logs is
unreadable.)

Can anybody help me to figure out the wrong parameter?

Thanks a lot,
Christoph

Have you tried switching to the legacy 1394 stack in Win7?

Yes I tried it but it fails too. But anyway under 32bit Windows 7 the driver
works already with the new OHCI.
Thanks for the suggestion.
