[LimeSDR] Issues with USB3 connected through mPCIe

Hi,

I am trying to connect LimeSDR to an embedded PC through it’s mPCIe interface. The connections seems fine but I am unable to get any data using the generic example FW images like GpifTousb (to test system throughput).

In short, loading GpifToUsb.img into FX3 (LimeSDR recognized as StreamerExample) and running application “Streamer” to get data throughput under Windows 7 32-bit.

It gives the following error:
“Xfer request rejected. NTSTATUS = c0000001”

While the same procedure works fine if I connect LimeSDR through USB3.0 port directly. Can it be a driver issue or something else?

Thanks in advance.

Regards

Just to add more information, the same issue is observed on Linux where the USB endpoints goes to STALL status. The connection is through a "mPCIe to USB3.0 converter card.

Can anybody please help?

Thanks in advance.

Regards
