Everything worked on this laptop computer Acer Aspire 3614WLCi using Debian testing till the last couple of upgrades. Hub Scanner etc, works on an older Acer 3650 laptop, with Debian Etch, and in windows on that machine. You might be correct suggesting not enough power.......... The scanner doesn't do anything with its carriage and there are no lights working in it when plugged in. I have changed from an external USB to Serial cable dial up modem. To an Ethernet satellite self powered modem. The dialup modem plugged into the bus powered hub ensured the USB system of the computer was constantly activated. The light was on all the time, because the modem was connected and working. Now the hub light goes on and stays on.... only........ when I have something like one of my external self powered DVD drives plugged in. This must be constantly demanding of the computers USB system through the bus powered hub. So the hub is activated and lights on. But when nothing that requires constant surveillance [turned off printer] is connected to the hub. The light stays out. My system sees, recognises and labels my scanner correctly. But the scanner doesn't demand power just by being plugged in. [EMAIL PROTECTED]:~$ lsusb Bus 003 Device 002: ID 04a9:220e Canon, Inc. CanoScan N1240U/LiDE 30 So the computer USB system doesn't kick in. Even when Xsane is evoked. It says it is getting a preview, but the preview pane is black, and the lights and carriage in the scanner remain off and stationary, respectively. If I plug in an external DVD drive, the hub is activated, the light goes on, the DVD reads and writes, and if I leave the external DVD drive plugged in, the hub lights still on and plug the scanner into the hub. The scanner works as described above. No lights, no carriage animation. If I leave the hub working by leaving the external DVD drive plugged in, and use another USB port ***directly*** to the motherboard of the computer [in the computers side] The scanner still doesn't have any lights working or carriage animation. I think it may be a power issue, but this was never the case previously? It's an interesting situation which is new to me. taogypsy:~# lsusb Bus 003 Device 001: ID 0000:0000 Bus 005 Device 002: ID 05e3:0606 Genesys Logic, Inc.

I think I like it better the way it is now, but then how do I get the scanner working? Too many questions and more questing required. Thank you for your interest and suggestion.
