Re: BUFFALO WLI-U2-KG54-AI USB adaptor stopped being 'recognized'



"spamlet" <spam.morespam@xxxxxxxxxxxxxxx> hath wroth:

I am wondering (amongst other things) if there is a bad connection somewhere
on the laptop's USB port hardware that is stopping it from being able to
deliver enough power to 'start' the wireless adaptor, but is still capable
of delivering sufficient to be able to run flash drives.

I don't think that's happening. I've seen broken connectors and blown
fuses on USB devices. The usual result is an all or nothing affair.
It either works, or it doesn't. There's too much data negotiation and
error checking going on for anything to partially fail in the manner
you're experiencing.

(I have had a look at opening up the laptop to get at the port assembly and
check its contacts, but it seems to be very difficult to get at, requiring
just about every other component to be removed first.)

Dell Inspiron 2600 as I recall. It's not listed here:
<http://repair4laptop.org/disassembly_dell.html>
You should be able to find disassembly instructions in the docs on the
Dell web pile. Bug me if you can't find them. I don't think you'll
be able to see the connections to the main PCB as many such USB
connectors are surface soldered. The better ones use plated through
holes in the PCB. With these, the leads are under the connector and
difficult to see.

There are also dedicated USB test tools and software avaialable. I
haven't used any. Search Google for "USB tester".
