I have a Series 3. I am trying to use 3 USB devices (Tuning Adapter, USB Wireless Network Card, and a the Tivo Slide Bluetooth Remote) I realized everything worked when plugging directly into Tivo and not using a USB hub. Since I can't find the AC adapter for the USB hub now, not sure if I should buy another USB hub and use the AC adapter. Or should I buy a USB to Ethernet converter. While the hub was working, the performance was hit or miss and I'm looking for a more reliable solution. Please let me know how you think I should proceed. Another USB hub or a USB/Ethernet converter?
