Please help us help you by telling us more informarion:
1) your iMac Model (processor type is a good start)
2) your Mac OS version
3) What type of "USB? A printer? a hard drive? a thumb drive? an iDevice? A keyboard? Posting "USB" alone leaves us guessing at your meaning.
If the problem is related to an external hard drive, plesae post its make and model so we can look up the specifications.
Actually...I post this in the wrong place..sorry
iMac, eMac. They sound similar in every language but English! I'll get the Hosts to move this to the eMac section so you don't have to repost.
The good news is we have two eMacs in the family: one the first generation; one the last.
When you get the messages, what ports are you using? It is fairly normal for a flash drive to fail when plugged into a port on the keyboard (low-powered port). If you used a port on the right side of the eMac case, then it should work.
Have you experienced any other odd symptoms with the computer? Unexpected freezes, video defects, or no video, etc? I ask because a fair number of 1.25Ghz eMacs had near-fatal logic board problems. As odd as the symptoms of the logic board problems seemed to be, it would no longer surprise me if it affected USB. If you are seeing other problems than this, I can post a list of serial numbers that Apple said contains the affected computers.
Thanks, Im new to the forum didn't notice they have one just for emac
No, its not on the keyboard. Just the right side of the mac. All three of them seem to be the same.
Um...I don't think it has any other problem. It just a bit slow, due to the age I guess.
Also, sometimes when its plugged in, then I open disk utility, it will suddenly disappear. ( Or maybe it ejected itself )
Well, let us check to see if your eMac falls among the affected units.
First you need the serial number. Easiest way:
Important: do not post your full serial number here.
See if it falls within these ranges:
- G8412xxxxxx- G8520xxxxxx
- YM412xxxxxx - YM520xxxxxx
- VM440xxxxxx - VM516xxxxxx
Being within one of those ranges doesn't absolutely mean yours has failed. You don't have the classic symptoms. Still, it's something we should consider "just in case."
Another thing: does ANY other USB device work properly when attached to those ports? Printer; other drives, etc?
You are in one of the affected ranges but so far, I'm not hearing any symptoms of logic board trouble. Are you the original owner or did you buy the eMac used?
Some affected eMacs were owned by schools who exercised the Rpeair Extension option (now expired) so there are machines in the affected ranges that have been retrofitted with reliable components.
Trying another flash drive is a good idea, as it seems the ports work for other devices.
I got this from friend. He it was "his" before, so I don't think it is from a school.
I tried it with another usb, Kingston, it works just fine.
I think...Not 100% percent sure thou...That I had met this problem before. Maybe it's a differnt usb.
I didn't take serious notice of it, and I was sure I didn't do anything just to fix it. I think a few days after, it works again.
