I just wanted to mention that in the Dell case both BIOS A02 and A03 (latest) have the same issue.
Is there a formal channel to report this kind of thing to Intel?
Hello Grantb5, thanks for sharing this information with us.
Before reporting this behavior to the engineering team I would need to get some additional information from you. I would appreciate if you could answer the following questions:
- Please let me know if all your systems have the latest BIOS version installed?
- Are you plugging the USB device directly to the computer or are you using any kind of hub?
- Would you please send me the system information? Please type “msinfo32” under search and send me the information you get?
- Also, can you run the System Identification Utility and provide the code given by the software? Intel® System Identification Utility - Identify Your Product
My guess is it affects virtually ALL of the PC's with this host. I have had reports from Dell, Lenovo and others.
My personal Dell Inspiron PC has the issue. You can refer to Reference Number 0292 9157 from your Intel Sys ID Java app. As far as the ms32info, do you want me to email that?
I also have personally tested two Dell Optiplex 3020's with different BIOS's and they both exhibit the behaviour. It's not a super common situation so perhaps not surprising that it might not be on the radar. Plus the end user can probably discover the workaround which is to unplug the USB device (even though the device in my and others opinion it conforms to the USB spec).
This is an interesting post. Unfortunately not answered.
I have comparable problems with Intel USB3.0 eXtensible Host Controller myself.
I have a dell optiplex 3020 with Intel 8 series chipset and Win7 proffesional. High speed devices do perform well, but the Full speed devices are slow. While the same FS device processes a number of commands on an Intel chipset 6 in 4-5 ms, the Intel chipset 8 needs 20ms or more. This has been verified with USBlyzer.
It seems that my 2.0 devices all are managed by the xHCI controller instead of the conventional EHCI controller.
I want to configure 2.0 ports as 2.0 and 3.0 ports as 3.0 (mixed port mode) to check whether my FS devices operate well again.
Any help is appreciated and thanks in advance!
Guys please make sure you have the latest BIOS version available for your system and the latest USB3.0 drivers from our site Intel® Download Center
Remember that these drivers are valid for the following operating systems.
If you are using Windows 8 and you are experiencing these issues, it will be necessary to contact Microsoft.
As mentioned above,
"I just wanted to mention that in the Dell case both BIOS A02 and A03 (latest) have the same issue."
I'm experiencing exactly the same indefinite hang on three completely different machines here. Are there any news on this topic?
