did the other USB cable have the connection where you can see 6 copper colour connections inside, as differnt camera's have different connections
As i have the Olympus E500 DSLR and the cable connections are the same as the FE220
Try
1) Connect Olympus to your PC (with usb cable)
2) Switch on PC... when in windows wait 2 mins..then
3) switch on Olympus camera wait to see if anything happens.
4) if it asks for a driver than install driver from CD
5) if nothing happens go to My computer and see if you can see the disk drive icon of the olympus drive
6) still nothing....Start >> control panel>> add new hardware, to see if it can detect your connected olympus.
still nothing
move the dials on the olympus around, as some DC require dial to be in PC mode or play mode....
check the connections on the camera for any damage...
try a different PC to see if your olympus works...
if not you could
(a) could be a faulty cable, try it with a replacement
(b) could be a loose connection on the usb connecter on the olympus, get it seen to, if its still in warrenty. if not get some estmates
or just
(c) buy a externel card reader, so that you just take the card out of the Olympus after taking your pics
Hope this helps
