Linux Newbie - Can't get Epson DS-30 Scanner to power on with Lubuntu

Hi All

Pretty much a hail mary shot on this one. I'm running an Acer Aspire One 522 with Lubuntu. I have been wanting to get my portable scanner (an Epson DS-30) running for quite some time, however I can't for the life of my figure out why it won't power up (its one of those models that is solely powered through the USB port and doesn't have a power button).

Here's the worst part - I'm brutally unfamiliar with Linux. I have a background of command prompts with DOS a long time ago, but Linux is practically a foreign language for me. However, I'm patient and adept at googling. Here's what I've figured out.....

I've installed ImageScan for Linux, and it recognizes there's a DS-30 attached, but gives a "could not send command to scanner. check the scanner's status." message

I've also tried VueScan, which detected the Epson DS-30 attached, however says "VueScan found an Epson DS-30, but no Epson software for this scanner was found on your system. Try downloading a driver for this scanner from epson's website "

I've installed the Linux drivers from the Epson Website, and they seemed to install, however no change there.

I also tried using lsusb to see if Linux detected the scanner, and it did find it... "Bus 001 Device 017: ID 04b8:0147 Seiko Epson Corp."

So, overall, it seems like Linux can see it, and at least partially recognizes it, but for some reason, the scanner won't power up (the LED indicator on it won't turn on).

I've eliminated the possibility of it being the scanner or the usb cable, as I can get it to power up on a Windows 8 system after installing the drivers and software there.

I'm wondering if maybe there is something different with how the USB ports on my system are configured? maybe the scanner doesn't like them?

Yeah, I'm really that stuck. So, any suggestions/thoughts/walkthroughs that anyone can provide would be immensely appreciated. I'm trying to avoid dual-booting with windows so I can regain the use of my scanner.

Thanks all,
Jason

Power to USB devices is not (normally) configured by the OS but by the hardware:

You said the scanner works with Windows 8, but was it on the same laptop?
Could you post the output from:
Code: 
sudo lsusb -v -s001:017
In particular what is the Device Status: at the bottom. But the full output would be nice as well. ;)
Have you enabled any powersaving features? For example, powertop will show USB ports as wasting power. TLP may disable USB power out as well.

Thanks for responding! Yes, using Windows on this laptop, I was able to get this scanner working. The output from that was...

As for powersaving features, there aren't any going on that I'm aware of.

Just had the same problem here. The solution is to be sure to install the "iscan plugin package" along with the "iscan" package (core and data), which you have already done. The Epson download website is not the best designed in the world, so it is easy to miss it - there are 3 packages total to install. My linux system is pretty old by now (Ubuntu 9.10 Karmic) but the driver seems to work fine. The power light only comes on when a scanner program starts up. I use Xsane.
