Problems using IssueVendorTransfer

Hi all!

I'm using Platform Builder 5.
I developed an USB Device Driver. But the Device want to drive, it needs setup and control strings to operate.
I try to send the strings with IssueVendorTransfer on EHCI Host Controller but nothing happens. i got failure messages, like DEBUGCHK failed in cpipe.cpp at line 893 and DEBUGCHK failed in Transfer.hpp at line 70.

But IssueBulkTranser on the Bulk pipe's is operate, there i can send messages.

Does any body know what i must to follow to use IssueVendorTransfer??


Thanks a lot!

I doubt people in here will know - this forum is more to do with legacy devices running CE.Net 4.2 or lower. I would suggest the newsgroups...
