My brand new raspberry pi 2 has defective USB ports. I have a brand new USB hub which is independently powered and connected to 2 USB hard drives. When I plug it into the pi and boot it up, the drives are not recognized - no entries in /dev, nothing in dmesg. When I unplug it dmesg indicates they were recognized then recognizes they were disconnected.

I bought another raspberry pi 2, same exact behavior. I tried a different USB hub with different drives, same exact behavior. It sees there is a systematic manufacturing defect in the USB ports. For more details:

Oh! I came across this as a possible issue between USB 3.0 and 2.0 with Via chips :http://www.linuxquestions.org/questions/linux-hardware-18/via-labs-usb-3-0-hub-will-not-recognize-a-usb-3-0-device-873399/
I believe your drives are 3.0 beacuse of the match of Pid from http://usb3speed.nirsoft.net/?pdesc=WD+Elements+10B8+USB+Device&vname=Western+Digital+Technologies%2C+Inc.&vid=4184&pid=4280
The raspberry Pi are USB 2.0 only and maybe iffy with newer 3.0.
Just saw,

The hubs and drives work fine with my raspberry pi 1, which is also USB 2.0, so I don't think that can be the issue.

I read about this issue elsewhere (can't remember) and it has to do with USB hubs and also loss of data at high speeds. My son has a Rasp Pi 2 and I will need to connect a USB hub soon. Let me know if you find a solution.

no solution in sight. I contacted element14, even though their name is on the box, they said I had to contact the distributor, in my case since I bought it from Microcenter (Micro Center - Computers, Electronics, Computer Parts, Networking, Gaming, Software, and more!) they directed me to Microcenter's distributor "MCM Electronics". I emailed them but they have not responded. So needless to say I won't be using the raspberry pi from element14 (newark) and I certainly would recommend against anyone else using them.

Sorry dllahr you had such an unpleasant experience. The only things I noticed, was the Pi 2 is needs power source that is very good. I slipped a power hub from Rosewill (New Egg internal brand) onto new Pi 2 and it works like a charm handling keyboard, wireless mouse, wireless nano, and sdr-dtl USB connector with a 2.1 ampere wall plug (for the hub).

Yep, I learned early on with my 1st generation raspberry pi the importance of the power supply. Both USB hubs that I tried were independently powered, and the raspberry pi had a dedicated 1 A supply.

The Pi 1 (before the A+/B+) and Pi 2 use a different USB controller. So clem57 's point is still potentially relevant. If you want to return it, element14jamie might be able to help.

Thank you Christopher, but I don't understand how it could be a software issue if the physical position of the USB connection solved the problem - twice. And thank you for the offer of help returning, I was able to return it to Microcenter.

dllahr Glad you were able to return it, incidentally the USB controller is hardware, it is the chip which handles the USB ports and the Ethernet controller on the Raspberry Pi.
