Hello, we have a RG200U-CN pcie modem, it works without problems in external pcie to usb converter, but when plugged into pcie slot on our device it only enumerates as “1782:4d00 Spreadtrum Communications Inc. Gadget Serial” and never switches to RG200U. The same pcie slot on the same device works well with all other modems so far tested (eg. EG25) this is a first problem we have encountered with it. If we connect the same RG200U pcie card to the system via usb and a pcie to usb converter it works without problems. Is there anything special about the pcie interface in the RG200U?
