Its not being recognised on Mint Linux 11, Lubuntu, or Windows XP. A month ago it was, on all of them.
I have given up on the PITA Kies as it has asked me to update itself for 3 successive updates in the last hour, it takes 20 mins to do each one!

Usually I just copy stuff over in Linux. Drag n drop.

Have done all the usual stuff that the search results bring up, none of them work.
Put it in development mode, PDA etc, put USB debugging on. No joy.

Starting to wonder if it could be worn connector pins in the phone? Its probably a year old, with very low usage. Sit in the Mrs purse all day.

Tried 3 different PCs, 3 x OS's, two different USB cables.

Anything I missed?

The only way to get stuff on it now is dropbox.

Not really that keen to reset it because I dont want to lose all my wifes contacts etc.

No errors from Linux, Windows just says: "USB device not recognised", but it continues to charge it.

Cheers
Jeff

Worth mentioning, my 7 inch galaxy tab which also runs gingerbread, and my baby galaxy (on froyo) both work on the above mentioned boxes (win and linux).

Something similar has happened to me recently, one of the pins inside the the micro usb connector had come loose and would no longer connect to my pc.

Then it got worse and the phone thought it was always charging which I found to be caused by the loose pin shorting to the pin next to it (could barely see under the x10 microscope at work).

I used a dental spike to line it all up again and I am extra careful when plugging it in ( I wasnt before )

I looked at replacing the micro usb connector itself but its different to standard ones as it has 7-8 pins instead of 5 which means the pitch is also different so the connectors dont have the same footprint.

Instead I am looking at buying the micro usb + pcb and ribbon cable from ebay.
Just a quick search showed me this one:

My SII is also about a year old.

My wife has the standard I9000 (SGS), but the hardware is very similar with your I9000T model.

She had a problem a while back where our computers wouldn't recognise the phone. If you plugged the phone in, Windows would go through the motions, but would eventually fail with an error message.

The problem turned out to be the internal solder joints where the USB connector is attached to the motherboard. I had to take apart the phone to get to the motherboard, and just touched a soldering iron to the connections to re-flow the solder. The phone has been working perfectly ever since.

I don't know if this is exactly your problem, but it's possible it's related.

Hmm, thanks guys, its starting to look like that might be the problem....
Pretty bad really. I better check to see if there is any warranty left on it.

Not sure if I would be comfortable waving a soldering iron in anything that smalls direction!

It's not as bad as it sounds. It's fairly easy to get at the pins at the back of the USB port, and you just need to touch a dry soldering iron to each pin for a couple of seconds. There isn't a lot of solder on each of the pins, so you don't have to worry to much about the hot solder bridging connections.

If you have warranty on the phone still, definitely go that route. If not, you may need to either go in yourself, or find someone who's brave (or qualified) enough to do it for you. Or, if all else fails, trade in for a newer phone

Hey I just checked and found out that it has about 10 days left on its warranty!
I cant believe how much cr^p is breaking down in our house right now within two years of purchase.

A 190$ kettle, an $80 thermometer, a $500 net-book, and now this. 3 of them under 13 months. All from "name" brands.

QUICK send it in for repair!

Alternatively if you dont get it in in time I could resolder the connections as mentioned above or I am about to purchase a new PCB assembly from ebay for $9US with free delivery and could order an extra.

I work for an electronics manufacturing company and am trained in IPC-7711/21 rework and repair proceedures :D

You might be better off finding a sparky for that as I'm more experienced at the pcb/component level.
