Vern:

Let me remind you that last year, specifically 29/12/2014, our esteemed colleague, zOner, was so infuriated at my oh so low European manners that he wrote me:

"nidany, I don't care if you started this thread or not - I'm getting real sick of your combativeness and negativity.  Give Dell time to investigate so we can ALL get the issue fixed, or live in your misery by yourself."

I sincerely advise you to stop harassing Justin - Dell lest you invoke zOner's wrath upon ye. Do remember what The Good Book says : "My wrath shall become hot, and I will kill you with the sword;" (Exodus 22:24).

You are trying to be logical - why not be more spiritual and wait patiently until Santa's next visit?

@Verngraner,

So far, Dell has been able to duplicate the following: After updating the E6540 to A12 BIOS, USB only works at 2.0 speeds.

I personally submitted the case to the Dell engineering team. Dell engineering is moving forward with the case and I will be monitoring it. The tracking numbers for this issue are all internal at this time. I will post back with any further updates as they become available to me.

Hello Justin.

Thank you for the update. I look forward to a solution.

In the meantime, would it be possible to revert the E6540 to an earlier BIOS that doesn't have the problem?

If so, can you let us know what version(s) do not have the problem?

@Verngraner,

Anything A10 and below should be fine, as long as you're running with wireless enabled in the BIOS. 

Go here:

Expand 'BIOS' then click 'other versions available'.

Justin:

Thank you for the downgrade instructions. This has worked for me and has restored my USB super speed connections.

Workaround to restore USB3 Super Speed on E6540

  1. Disconnected ALL the USB peripherals from the machine
  2. Downgrade the BIOS from A12 to A05, (machine will restart)
  3. Log back in, open DEVICE MANAGER and remove all items under "Universal Serial Bus controllers", ticking the check box "uninstall driver software" on each item where it is offered
  4. Downloaded "Chipset_Driver_8DT62_WN_9.4.0.1016_A00.EXE", and install it
  5. Downloaded "Chipset_Driver_5JFFN_WN_2.5.4.40_A05.EXE" and install it
  6. Reboot
  7. Logged back in then connect your USB peripherals one by one noting the prompts

Each device you connect should be properly recognized for its maximum speed level as it did for me. Use USBTreeView to verify. My results are shown here:

So, this workaround brings back my USB3 speed. I hope this other folks while we are waiting for a real fix from Dell.

Note to Justin: Thank you for your on going work on this issue. Please keep us informed as progress is made.

Vern,

I downgraded to A10 as suggested by Justin.

Did it straight - no disconnections, no uninstallments.

Everything went smoothly and USB viewer reported that all ports are now "usb 3 Supersped".

In my case there was no need for the procedure described by you. This might be related to differences in configuration and/or different peripherals.

Glad to hear that worked on your system. Smiley Happy I tried doing the downgrade to A10 and after the reboot my external hard drives were still reporting as USB2.0. Smiley Sad

I maybe went a little overboard in the steps I used, but the system came back with USB 3.09 after I did so I wanted to document what worked out on my system. I'm just glad to be back to full speed as I am dependent on my external drive array for work!

I'm hoping Dell comes back with a fix for this issue soon so I can get patched back up to the most recent bios and drivers.

Hi vern,

A few months ago, with the older bios update, I had a similar problem with my external HDD's.

Solved it with 13 US$ (really), by ordering a powered usb 3.0, 7 ports hub, from Aliexpress. Works like a charm!

I have the same problem with all four ports running at USB 2 not USB 3.  Now one receives the warning, but I suppose they never worked properly.


Any further news?
