USB 3.0 and USB 2.0 - technical background and Windows workaround.
Some background information to shed light on this subject:
- USB docking ports are not all identical as they utilise different chipsets from different manufacturers.
- USB audio modules have a hardware+software to 'communicate' with these USB ports.
Computer audio is dynamic so we can only test to the very latest and if a new change comes along, we like any other manufacturer, will follow-suit. We try our absolute utmost to stay abreast but new changes/updates always occur. This is the ever-changing nature of computer audio.
A sizeable number of iDSDs have been shipped. The Firmware in all of them is based upon the official USB Specifications. We have tested this with a number of computers, but it is impossible for us to test with every model and make. Thus far, the USB 3.0 issue is comparably infrequent - for some of the newest Windows PCs and the latest MBPs.
We have identified firmware changes that should overcome all currently documented USB 3.0 issues, however the changes needed are far-reaching (almost a complete software re-write). iFi's in-house programming must take all the time it needs but rest assured that we are pulling out all the stops to make the solution available as soon as possible.
The Intel (and others) USB 3.0 implementations have well-documented, substantial issues, which depend also on implementation in the Computer and driver software. Hence, this is why the USB3.0 issue works with some USB3.0 ports and not with others. These issues with USB 3.0 for both Windows and Mac are widely discussed, but usually relate to external HDDs or USB memory sticks.
The underlying issues are with hardware (USB controller chips) and Software drivers not conforming to the official USB 3.0 Specification.
iFi workaround for new Windows Computers with USB 3.0 issue
(Please follow this link and the instructions):
You can see a screenshot of an example for setting this in the BIOS here:
Please refer to your computer's manual for details on how to access the BIOS setting screen.
We are examining workarounds for Mac...
Updates will also be found here:
If you are one of the few whose USB3.0 port is not okay, iFi really does appreciate your endeavours.
Anyone who cannot use the iDSD with their standard computer setup and does not wish to wait for the update, should discuss a return with their retailer - we formally apologise for any inconvenience caused.
Last but not least, those who wish to be notified to test the new firmware as soon as it is ready, drop us a PM or email: email@example.com
We thank you in advance
