I have a problem with the USBs on my other computer.I have un-installed them re-installed them updated the drivers etc but they still seem not to work.I now suspect it is a physical problem with them.Does anybody know of a way to check them.They only seem not to work when I connect the modem to them and then try and connect to the internet.The modem had an led which flashes red.The modem is fine with this computer.
