  1. Hi Jon, Thank you for your involvement. Did you receive the Tripp Lite hub and manage to reproduce the issue? Best regards, Vincent
  2. Hi Jon, The two hubs references are: - Tripp Lite U225-004-R - HP Z Display Z24i 24" Monitor (Integrated USB hub) Best regards, Vincent
  3. Hi Jon, Thank you for your message. We already used the concerned USB hubs with other peripherals (USB keys, Xilinx USB Cables, etc...). I logged the output of the dmseg for the two following scenarios: Scenario 1: When Digilent JTAG-HS3 cable is connected to USB port (No USB hub): [63143.414614] usb 3-6: new high-speed USB device number 56 using xhci_hcd [63143.431078] usb 3-6: New USB device found, idVendor=0403, idProduct=6014 [63143.431087] usb 3-6: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [63143.431093] usb 3-6: Product: Digilent USB Dev
  4. Hi Jon, Thank you for your message. We are on Fedora 20 and unfortunately can't update to Vivado since our FPGA devices are quite old and only supported under Impact. Best regards, Vincent
  5. Hi Jon, Thank you for your support. Both hubs we tried on Linux were externally powered. A try on a Windows machine revealed a perfect behavior of both cables and hubs. Best regards, Vincent
  6. Hi, We would like to use several Digilent JTAG-HS3 cables (up to 8) on a PC with Linux via one or several USB hubs since the number of USB ports on all computers is limited but we currently don’t manage to make working a single JTAG-HS3 with a PC with Linux via a USB hub. We tested on two different usb hubs (1 dedicated device, 1 integrated to a screen) and computers (1 desktop, 1 laptop) but the only configurations which work are: no usb hub and either a usb port of the laptop or a usb port on the rear panel of the desktop. Can someone say us if similar issues are already known
