Problems with USB

[tapyeno]

Until a wek ago my USB connections were working fine for my memory
sticks, scanner and nano ipod. Recently I keep getting error message:
"USB Device not recognised" for all I try to connect. This does not
happen for one of my memory sticks, but does for three others. I can
download from my digital camera also.

Can anyone explain what may have happened and how it can be fixed.

Thanks,

Pat
