TP-Link Dual-Band Wireless :: TL-WR2543ND / USB External HDD Not Recognized

Model : TL-WR2543ND
Hardware Version : V1
Firmware Version :

ISP : I have an external HDD that I regularly use in any computer I have access.It's an HDD enclosure 2.5" 3.0 USB, with a 750GB WD HDD inside. I use it in computers with all versions of USB, even in my TV. It doens't require an external power source, and just have 01 input/output, which is a USB port.After plugging it in the router (running with the last available firmware from TP-LINK - 3.13.27 Build 121207), I entered the setup screen of the router, and under USB Settings, pressed RESCAN, but the HDD wasn't recognized.What happens is that when I plug it in the router, the LED in it starts blinking (in normal usage, the LED becomes red for a couple of seconds, and then becomes steadly blue, when it gets connected into a equipment). It is probably a matter of power, as if the router wasn't providing enough power to it when it's plugged.Afterwards, I've made the following tests:

1) Used this External HDD in 3 different equipments (a notebook, a netbook and a TV), with different versions of USB ports. It was recognized and read normally in all of them.

2) I tested a pendrive with the router. After RESCAN, it was shown normally in Storage Sharing page.

3) I have downgraded the firmware to 120509 version, plugged the HDD in the router, and once again, it was an unsuccessful try.

What I can conclude from those tests is that:

1) My External HDD is working normally;

2) The router's USB port is working properly;

3) So, if both are working, it can only be a matter of compatibility between them.
