iOS upgrade cocks up iPad USB connections
Slabber jabber flabber well and truly gasted
Apple's iOS 4.2 upgrade has prevented data being read from some USB devices because the fondle slab puts out five times less power than before.
The iPad has a camera connection kit enabling pictures on SD cards in digital cameras to be transferred to the iPad. This works well with the previous iPAD O/S, iOS 3, but that has 100ma going out to the USB device whereas iOS 4.2 only dribbles out a weak 20ma, not enough for many USB-connect devices.
An Apple support discussion forum thread covers the issue.
One contributor, Gshackman, with a Blue Yeti microphone bought from an Apple Store to work with the iPad camera connector, has the same problem; insufficient power for the mike following the iOS upgrade. He posted this point: "Come on Apple fix your mistakes, do a little testing before you turn your user base into beta testers!"
Using a powered USB hub apparently works as a fix. There has been no official communication from Apple yet. ®

Wrong type of USB.
You're assuming that the "U" stands for "Universal".
Mr Jobs has simply re-defined it to mean "Unsupported Serial Bus".
There we are. All cleared up?
Reminds me aof a joke we used to tell about MS developers. Plus ca change:
"How many Apple designers does it take to change a light bulb?
- None, Steve Jobs simply declares Darkness to be the new standard."
Electricity
Something wrong here. If they are trying to improve battery life what they are doing is introducing a rule that says nothing that draws more than 20mA will be allowed to work with the iPad. They are limiting current to 20mA. Somebody at Apple has clearly made the incorrect decision that nothing drawing over 20mA is likely to be used with an iPad. You can't take a device that needs 50mA to operate an restrict it to 20mA and expect it to work. Somebody at Apple clearly doesn't understand that.
The story seems to suggest that the USB ports pushed out 100mA under iOS3 regardless of the device connected. That's just plain stupid. If a device draws, say 10mA, then it will draw 10mA regardless of whether the port can deliver 10, 20, 100 or even 1000mA. So a device that draws less than 20mA now would have drawn less than 20mA under the old OS. It wouldn't have miraculously pulled 100mA before just because 100mA was available.
When dealing with RDS.
The only way to win is not to play.
USB banjaxed.. Well.. It works for the officially sanctioned devices.
Reception dodgy. Not holding it right, and every phone drops calls when the antenna is blocked.
Non functional screen. The Steve is encouraging you to use your imagination.
3 inch metal spike shoots out of the earpiece when you answer a call, The Steve is helping you, by forcing you to slow down and mellow out.
Doorstepping god botherers, Scientologists, Apple fanboys.. Same strategy applies.
Do not return eye contact.
Do not engage in conversation.
Do not attempt to reason with them.
They win by making you want to eat your own face in order to distract from the stupid radiating from their pre programmed smiles and their pre approved talking points.
"Using a powered USB hub apparently works as a fix."
Yeah, right.
So you have your mobile tablet and your mobile USB device. All you need to make it all work is a powered hub, its transformer and a convenient (but decidedly immobile) power socket........FAIL!
That ain't a "fix". It'd even be charitable to describe it as a workaround....
Incidently, the USB 2 spec defines a "Unit load" as 100ma and states that devices are entitled to draw up to this, until such time as they ask nicely for more in numbers of units. Sounds like Apple are also playing fast and loose with the standards here.
@BigCW
So let me get this straight. Not only are people barred from using Flash and unsanctioned apps. But now the almighty Jobs has stopped people using "unofficial" USB devices.
Is that really what you're saying?
Has Jobs finally lost the last bit of sanity he has left?
