Why are USB 2.0 devices connected to a USB 2.0 hub not immediately recognized by Red Hat Enterprise Linux (RHEL) 3? - KB Article - 173811


Red Hat Enterprise Linux 3 does not immediately recognize USB devices connected through a USB 2.0 hub.

When you plug a USB 2.0 device into a USB hub attached to a system, the kernel may not recognize the new device immediately.



Run kudzu to detect the newly attached USB device.

If this occurs, run kudzu to detect the new device.

To run kudzu, perform the following steps:

  1. If you are not at a command prompt, press <Ctrl>+<Alt>+<F1> to open tty1.
    Tty1 opens and displays a login prompt.
  2. Log in as root.
    The command prompt appears.
  3. At the command prompt, type kudzu and press the <Enter> key.
    The system scans for new devices and configures the newly attached USB device.
  4. Type exit and press the <Enter> key to log out of tty1, then press the <Alt> and <F7> keys together to return to X Windows.
