Wonder if anyone has idea what might be happening here but whenever I'm connected to the internet and plug a pen drive in and then unplug it I always find that the connection drops and have to reconnect. As I only have four USB ports I use the back two for my printers and one of the two on the front for the modem. I alternate the spare front one for an external hard drive and a pen drive. I did try putting my modem into one of the back ports but it didn't help so does anyone any ideas why it might happen?
