  • 1.  USB Storage Devices Not Recognized

    Posted May 15, 2014 08:56 AM
    Having issues accessing any USB storage devices on a works laptop. The laptop is running Windows 7 SP1 and Encryption Desktop 10.3.2 [Build 15238] (PGP SDK 4.2.1). Plugging in any other USB peripheral such as keyboards, mice etc all work fine but not storage devices (i.e. Pen Drives, External Hard Disks). If I remove Encryption Desktop from the laptop, USB storage devices then connect as normal, strange?
     
    Does anyone know why this happening, or how to resolve the problem?
     
    Laptop: Samsung ATIV Book 9 Plus (running latest (UK) driver set from Samsung)
     
    Cheers

    What function is SED performing on this laptop?  Email? Hard Disk? File Encryption?

     

    Does the device appear in Disk Manager or Device Manager at all?

    SED is performing hard disk encryption on the laptop.  USB Storage devices appear in Device Manager with yellow exclamation mark, stating:

    This device cannot start (Code 10)

    Hi cdavies, Is this a standalone or managed client? If managed, how is the Consumer policy configured in what concerns Drive Encryption? Rgs, dcats

    I would add the following additional questions:

    1. Is the system using a dock?
    2. Are the ports USB 2.0 or USB 3.0?  (Specs from Samsung show 2x USB 3.0 ports as the only USB ports)
    3. Are the devices USB 2.0 or USB 3.0?
    4. Have you checked to make sure the USB 3.0 drivers are up to date and active, and that the 3.0 root hub is still active after installing SED?

    It is not expected behavior that SED would block device drivers, but it looks like the system you referenced only has USB 3.0 ports, so the policy applied for the system might be a factor.  When the policy is set to make external drives read-only, it should still initialize them, notify the user that they are going to be set as read-only, and be accessible.  It is possible that if the policy is setting them to read-only (or otherwise trying to manage the external drives), and they are on USB 3.0 ports that it could cause some issues, since USB 3.0 is not supported as of yet with SED.

    If there is no policy applied to the external drives by SED, I am not sure what might be causing that sort of issue, as the drives should mostly be ignored.  If the policy is set to allow users to encrypt/decrypt external drives, you may want to try disabling that also just in case.

    Thanks in advance for your answers!

    I hope Michael's post was helpful. But if not, I would suggest maybe giving us the output of drivers in the filter provider order using fltmc. Here are some quick/easy steps to do so:

     

    1) Start --> Run --> cmd

    2) fltmc

    3) take a screenshot of the full output of this command

    4) attach to this thread

    Thanks!
