USB memory stick problem
I've hit an odd problem with my 8GB memory stick. I plug it in and get the message 'device not recognised'. I know these fail suddenly even when well treated, and I tried it in all 6 ports. same result.
Not being too confident I would find anything if I opened it up I tried two more memory sticks that had not done the trip to PNG and back and a dozen X ray checks. Same indication, item not recognised.
Then to confuse me number one daughter (a bit like Charlie Chan's number one son, kiddies are numbered here) plugs her USB cable to handphone in and it works perfectly.
So what can I do to check out the problem, any help most welcome.
