Problem with connecting 2 identical drives to the R9000.

Hello,
I have a problem with the R9000 - Nighthawk X10 AD7200. I am trying to connect 2 identical drives (ST2000LM 015-2E8174) through 2 identical USB adapters (Vendor: usb 0x1e1d "Kanguru Solutions", Device: usb 0x20a0 "JMS579") but if both are connected together either neither is visible or any operations are possible for only one of them. Even if both are listed (U: \, T: \), any share change affects both items in the list, and actually only one drive.
In the options: Advanced settings - USB settings, if I want to set only the allowed devices, I can add only one drive, even though both drives are listed.

It looks like one is only a link to the other.

Each of these drives separately connected works without a problem.

Regards.

    It could be that they're requiring to much power when connected at the same time. 

    Are they powered usb devices? or unpowered?

      Thanks for the answer.
      Seagate ST2000LM015-2E8174 (2.5 inch) drives are connected via the Icy Box USB 3.0 - 2.5 "(IB-256WP). They are powered by USB, but both drives keep spinning and LEDs indicate normal operation on both drives all the time.

       

      Regards.

        right but if they both work while plugged in seperate, it isn't a router issue. Its more than likely they require to much power to be powered over the usb bus for both devices.

    Wondering if the router only supports 1 USB drive connected at a time...

      The router can handle 2 disks at the same time. For example, when replacing one of the ST2000LM015 drives with a Verbatim flesh (pen), the problem no longer occurs.

        Possible same model convention used between two same model drives is confusing to the FW.
