@gruber An iPhone can transfer video over Wi-Fi at vastly higher rates than USB 2? Or am I missing something about that—Files or...?

@glennf Not that much faster.

@gruber Damn, Daniel, am I going to have to test this now? Or wait for USB-C. BTW, the anger and frustration over USB-C seems to have settled—I no longer get the same volume of email about it or read the same frustration in bulk online. The reason? Cheaper cables and more of them. People were particularly angry when it was both *confusing* and *expensive*. Also, OWC has a quite affordable Thunderbolt 4/USB4 cable line-up: https://eshop.macsales.com/shop/owc-thunderbolt-4-cables
OWC Thunderbolt 4, USB 4 Cables - Mac and PC Compatible

The universal Thunderbolt / USB connection cable that's compatible with Thunderbolt 4, Thunderbolt 3 and USC-C equipped Macs, PCs, and mobile devices.

@glennf Wow, good prices indeed. And that 0.3m length might be perfect for the backpack.

@gruber That issue you mention of the 480 Mbps USB speed over Thunderbolt cables…it's so maddening because there's no good way (no marking, no macOS/iOS/iPadOS alert) about the speed. Apple could have a simple interface speed presentation…which they do in Migration Assistant. Tell you what the throughput is.

@glennf @gruber A great feature for any Mac with ≥2 USB C ports would be built-in cable testing. You plug both ends of one cable to the Mac, and the OS automatically detects that, no UI needed, and pops up a dialog saying “this cable supports x mbps and x Watts power delivery”. That’s it, there is no step 3!

@sidb @glennf @gruber I keep saying that I have no need to upgrade my M1 Mac. I think you just thought of an instant-upgrade feature for me.

@disappearinjon @sidb @glennf @gruber my Denon receiver, and many from the last few years do similar for HDMI cables. Handy when buying a new cable.

@NitP @disappearinjon @sidb @glennf @gruber out of curiosity, which receiver is this?
Show threadNitSep 4, 2023

@CrucialTK @disappearinjon @sidb @glennf @gruber mine’s a 2020 X3700H. The manual I linked to is for older models, page 4 has a list. I’m pretty sure newer models have the same functionality.

They don’t really advertise it though. Pretty sure it’s not in the standard user manual. I saw it mentioned in a forum years ago.

@NitP yooooooo! Did NOT know about this and I have a Denon. Another reason to appreciate it!

@sidb @glennf @gruber Does that really not work with plugging in only one end?

@gernot @sidb @glennf @gruber just reading the data from the chip can be problematic because cheap ones tend to lie apparently 😢
Show threadsidbSep 4, 2023
@bodo @gernot @glennf @gruber If I were designing such a feature in theory, I’d have the computer read what the cable reports and then do a quick throughput test up to the reported number to verify. Assuming the USB chipset /hardware allows that, which is beyond my expertise.

Can my cable support USB 2.0/3.0/3.1/3.2, power delivery? Is a wire broken?

@sidb @glennf @gruber it's not like they don't do it already to some extent. Ever saw the USB cable short circuit alert on a mac? 🙂
