Alert! Need additional confirmation on this!
Dell Level-3 Technical Support can not explain why numerous XPS 15 (L521X) laptop USB 3.0 Super-speed ports perform at only USB 2.0 High-speed. USB 3.0 compliant devices do NOT perform at USB 3.0 Super-speed. None do.
This occur on numerous units, Dell Level 3 Technical Support says. "It's random", they say. In my expereince, bugs are not random.
Dell's "My Dell Support Center" diagnostic software confirms this, as it shows the USB version and speed, both.
It fails USB.org's USB 3.0 Command Verifyer tool tests. Found under SuperSpeed USB Software and Hardware Tools, as "USB30CV Tool". It confirms connected devices are indeed USB 3.0 compliant, BTW. It is at: (http://www.usb.org/developers/ssusb/ssusbtools/USB30CV_Releasex64_1.0.1.2.msi)
Of interest, Dell has offered to fully refund the entire amount of my purchase to return this to them, 2 months after my purchase. Is this a serious issue? Does it remain publicly unknown? Why not provide a fix for this? Why the refund?
Can anyone else confirm, or debunk, this on another Dell XPS 15 (L521X) laptop? Yes, I know it seems highly unlikely that no one has yet to discover such a huge bug if indeed it exists -- yet it's not impossible. It is not an obvious bug to notice if one does not look for it. The fact that it has gone to Dell Tech support Level 3, and still has no resolution, speaks for itself.
This strikes me as a potentially significant bug that possibly affects numerous Dell XPS 15 laptop users. I was told Dell has sold over 400,000 XPS 15 units.
Yet, this falls outside of my area of expertise. Hence my call for expert help and independent confirmation.
A Service Request for this remains open regarding this under my name. I first diagnosed and reported this issue to Dell Technical Support on 12/29/2012. After hours of calls over several weeks this still remains unresolved and open.
The XPS 15 L521X model has three USB ports, all three advertised as USB 3.0 compliant Super-speed ports. It has no other USB ports besides these. It has no USB 2.0 ports.
NOTE: None of the USB ports on the Dell XPS 15 L521X appear colored blue, as many USB 3.0 ports do traditionally on other devices. This does not indicate anything conclusive, yet it seems of interest given the issue.
My laptop details:
Dell XPS 15 (L521X) laptop
Service Tag: 75HTJV1
OS: Windows 8 64x
Purchased: December 2012, direct from Dell online, for personal use.
All drivers and BIOS updated to latest versions from Dell.
Windows 8 drivers up to date.
BIOS USB Debugging option: disabled (DEFAULT)
Hope to hear from someone who can shed better light on this. Thanks.
