I recently bought a Newlink USB 2.0 host card and a Sitecom USB 2.0 hub for my PC and have fully installed them. They work fine with my printer (Canon IP4000) and my Nikon camera, but when I try to connect my Sagem ADSL modem it won't connect to the internet. It recognises the modem at first and then I try to connect and then it doesn't. Very frustrating!! I have reinstalled the modem and updated drivers but to no avail. Please help!!
The idea of getting the hub was to try and stop the modem dropping off when connected to the internet as I was told that this may be caused by drops in power by the PC. If I plug direct into the host card it will still run from the power of the main unit.
I had a similar problem with my BB connection when I moved my PC into the living room and used a Phone extension cable to plug the modem into. The modem refused to work from it so I used a USB extension cable instead and plugged the Sagem straight into the phone socket, using a filter of course and that works a treat, no more problems.
The link above could answer your particular problem.
Your correct in saying that disconnection problems can be caused by running the modem direct from the USB connection on the PC itself, but this only applies if you have several other USB peripherals running from the same port.
Try connecting the USB modem direct to the PC USB outlet and running your other hardware from the powered hub.
I'm fortunate in that my modem will run quite happy from a 4 port card in the rear of the PC along with three other items of hardware at the same time, but like you, if I try to connect my USB modem through a powered hub it will not connect. I suppose some modems do not get along with some powered hubs.
