"Like apple usb"
In what way did you mean that?
- chaosmachine 16y agoApple USB keyboards notoriously come with a USB extension cable that's notched in the middle, so it doesn't fit other USB devices. Here's a picture: http://imgur.com/Aweqo.jpg http://imgur.com/Aweqo.jpg Technically, if you're willing to risk damaging it, you can force a regular USB device in there, but it sticks out at a weird angle because of the notch.
- philwelch 16y agoThat's an example of lock-in that makes absolutely no sense. Why would you do that with USB extension cords of all things? The only reason I can think of--it physically locks the cables together better so it doesn't pop open in the middle of the extension cord where it's difficult to reach and reattach.
- gxti 16y agoI'm pretty sure they do it because the keyboard can't source the required 500mA of current. They "proprietarize" it in order to keep people from plugging high-current devices in.
- chaosmachine 16y agoThe keyboard itself contains a 2 port USB hub (regular ports, btw, with enough juice to power a Wacom tablet and charge my phone at the same time), so I'm not sure that makes sense.
- gxti 16y agoNever mind, then. I have no idea why they did it but there's probably a perfectly valid technical explanation.
- gmlk 16y agoI don't know about the current systems, have been wireless for more then 4 years now, but the original iMac had non-standard USB usage because Apple wanted the "power" button in the keyboard, while the USB protocol did not support this usage, at least it didn't at the time; I don't know if this has changed since then. http://forums.macrumors.com/showpost.php?p=11022485&postcount=16 http://forums.macrumors.com/showpost.php?p=11022485&post...
