From: Christoph Diener on 27 Apr 2010 09:31 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

From: Christoph Diener on 28 Apr 2010 02:02 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. "Maxim S.
