handling IssueVendorTrasfer with TransferBuffer == NULL and TransferBufferLength = 0 on CE 6.0

Hi ,
I am working on a USB device from one our client on windows CE
6.0.
The client driver for the device is sending a VendorRequest to
the device with TransferBufferLength == 0.
The intention is to just send a command to the device. The client
driver doesn't expect anything from the device.
The above case is failing in CE 6.0.
It is failing in file cpipe.cpp in function
CPipe::IssueTransfer() at line number 1185.
Does this means CE USB driver is not designed to hadle this case?
Is there any workaround for this issue?

Regards,
Sriram.R
