You mean your USB DSL "modem", and your printer, right?
Your hub should have an optional power adaptor to work in "powered" mode. Did you try that? (Doubt that's the problem though)
I only have two USB connections on computer and I need 2 additional ones so purchased a hub (4 connections). Neither my ISP or my printer will work if connected to the hub. What can I do?
Many thanks for any suggestions.
