10.1 iMPACT, ChipScope, System Generator, XMD - Platform Cable USB cable disconnects with "DeviceDetach: received detach for device handle 0x......." message

Description

On Linux, when more than one application attempts to connect to the Platform Cable USB and subsequently disconnects, both applications are disconnected. 

A message indicates that the cable has disconnected, and the following message appears when any operations are attempted (this includes Cable Unlock operations). 

INFO: write cmdbuffer failed 2000000F

This behavior occurs in the following scenario:

  • A first application opens the Platform Cable.
  • A second application opens the same USB cable.
  • The first application closes the cable connection.
  • The cable connection is lost for both applications.

Solution

You can use one of the following solutions to work around this issue:

  • Use the Libusb Driver. For details on how to use the Libusb driver, refer to (Xilinx Answer 29310).
  • Close the cable after use; before opening the second application, close the cable in the first application.
