#14091 new bug

USB 2.0 compatible USB 3.0 external hard drive is not found/cannot be mounted

Reported by: Stacked_Lambda Owned by: nobody
Priority: normal Milestone: Unscheduled
Component: - General Version: R1/Development
Keywords: Cc:
Blocked By: Blocking:
Has a Patch: no Platform: All


A Western Digital Passport external hard drive (1TB - Native USB 3.0 with USB 2.0 Compatibility) is not found and cannot be mounted.

The notebook is a HP ProBook 4500 G3 with i5-6200 CPU and heavily customized BIOS.

This is experienced with HRev51877 - Hybrid - 32-bit booted in Legacy Mode via the internal optical drive.

The issue occurs whether the WD Passport drive is connected to a USB 3.0 port or to a USB 2.0 port (both types of USB ports are available on ProBook 4500 G3).

However, the WD Passport drive is found and can be mounted on a notebook with only USB 2.0 ports (Acer Aspire One 721 with R1 - Alpha-4.1 booted from USB Flash drive).

Please attach your syslog from A4.1 and current nightly.

It is a bit difficult to get to a "saved" SysLog when booting from a read-only medium.

I ultimately elected to display the SysLog, write its content down on paper, and transcribe it into a text file.

I added some details about the notebook and external USB 3.0 drive. I abridged the SysLog to something I could more easily transcribe. Let me know if any critical bit of information is missing.

I get the same SysLog information whether the USB drive connected at boot time is the USB 3.0 WD My Passport, a USB 2.0 Flash Drive, or a USB 2.0 PATA Bridge with an old 2.5" drive.

The only difference in behavior is at the desktop level with the USB 2.0 Flash Drive and USB 2.0 PATA Bridge being shown in the list of volumes (when right-clicking on "Mount") while the USB 3.0 one is not.

I attempted to get to the SysLog via the "ALT SysReq D" keyboard short cut. However, this is not recognized by the notebook. The keyboard does not even show "SysReq" on the key which has "PrtScr".

Is there a way to get to the SysLog when using the Debug application?
