USB Optical drive not functioning properly

[Blue_Dragon360]

Hello!
I purchased this drive for my project: http://www.amazon.com/gp/product/B00DBV ... UTF8&psc=1

I am having trouble getting the raspberry pi to recognize it. It works on a different computer, and when I insert a disc it starts to spin.

I went through the "USB device not working? Click here!" thread, and here are the logs:
It's entry under lsusb:
`Bus 001 Device 013: ID 0e8d:1806 MediaTek Inc.`
When I unplug it, then plug it back in and run dmesg, the log of it being loaded is here (looks like there's a power error?):
`new USB device found, idVendor=0e8d, idProduct 1806
new USB device strings: Mfr-1, Product=2, SerialNumber=3
Product: MT1887
Manufacturer: MediaTek Inc
SerialNumber: S16D6YMF900CAW
rejected 1 configuration due to insufficient available bus power
no configuration chosen from 1 choice
No support over 100mA`

This thing is running from a powered hub, and so far everything else is fine. On the player itself it says it needs "5V 1.3 amps".

Any suggestions?

In my experience, optical (CD/DVD) drives are extremely power hungry - for example whilst the one shown here:

worked fine with the Medion laptop it was supplied with (and also, later, with other laptops & netbooks), but to get it to work through a powered hub** I had to use this 5V 2A PSU:

Trev.
** IIRC, regardless of whether the hub was connected to a netbook or a Pi.

Hm.. I see what you're saying. Sadly, having an extra PSU isn't really an option for this project.. Any way to figure out a DVD drive, or should I send it back?

Do you really need a DVD writer? If the requirement is "read only" you may be able to find a less power hungry device. Are you using a "B" or "B+" Pi? What other devices are plugged into the powered hub?

I only need a reader. I looked some for just a reader, but I decided to just go with a writer, so that could be an option. I'm using B+, and plugged in to the USB hub is the pi itself (to power it), two 2-port unpowered hubs (for the outside) and two low-power controllers plugged into those. The DVD drive is plugged into the fourth port of the main hub on the inside.
