Re:USB3: Why it's a bit harder than USB2 by vlovich123 on Wednesday October 07, 2020 @11:14AM (#24709080)
Is this a uniquely USB3.0 problem? I've been in the consumer electronics spaces for 10 years & from the very beginning I would hear reports about problems for 2.4Ghz WiFi any time you were transferring data on USB (& usually EEs try to tackle this with shielding if USB + WiFi coex is important). I have not heard of this as uniquely new to USB3.

I have never heard of interference with Iridium & GPS for USB2/3 and I worked on a team that was responsible for GPS at Apple, but it's entirely possible there's shielding needing to account for this & I just wasn't closely involved in it. If this were actually an unsolvable problem though, I would expect CarPlay & Android Auto would have a problem when you use your phone for navigation & start playing audio through USB. Maybe that's not enough traffic frequently enough to generate the noise needed to make it unusable, maybe the EE problem you were having was different, or maybe there's just good shielding in phones to avoid this as a problem.

Paper by Intel about USB 3.0 interfering with 2.4 GHz WiFi. The fact that the USB-IF hosts this paper on their own site seems to be a strong endorsement of their conclusions too.

It is worth noting that the RF noise generated by USB 3.0 covers a fairly wide spectrum from basically zero up to the mid-4 GHz range, but it gets discussed mostly in the context of interference with 2.4 GHz because most USB 3.0 capable devices don't have any other radios in that range to interfere with.

I didn't say USB3 doesn't cause this interference. I was saying I don't recall this being a uniquely USB3 problem (unfortunately all I have is my memory to go on here that we had desense issues with USB+2.4Ghz when I worked on the Palm Pre & Jawbone Jambox).

Given the report is 8 years old, I find it hard to believe this isn't an active thing that's designed around. Hell, you can buy USB3 WiFi dongles that do 2.4 Ghz. If this were a critical flaw that's unsolvable such a device wouldn't be possible to build. Even Table 4-2 indicates different mouse models have different performance characteristics, indicating not all 2.4Ghz devices are similarly sensitive to the problem.

My Lenovo 2.4 GHz mouse and MS Sculpt keyboard suffered from interference when the receiver dongle is plugged directly into a USB 3 hub with other USB 3 devices, and this is a well known issue. I fixed it by buying a shielded usb cable to move the receiver away from the interfering USB 3 hub and closer to the keyboard/mouse themselves.

Same issue with logitec mouse, mbp, usb3 hub dongle, buying an old school 4 port usb2 hub and running the cable away from the dongle, problem solved. Gotta love the future
