That sounds better.

Yet, it is still being unrecognized by my pc. I went to check the device manager, it says my libra is an unknown usb device (device descriptor request failed). I tried to reboot my pc/used usboblivion after googling for some solutions but it still remains unknown.
The usual suggestions are to try different port on the PC, cables or other PCs. Or use a hub. I have no idea why, but some machines just don't like these devices. I have an issue with my Glo HD and the laptop I use. It can connect and Windows will see it. But, put any load on the connection (copy a large file, let calibre connect) and the connection drops and puts the USB port in an unusable state. But, it works perfectly with the other computers in the house. And all the other Kobo devices work with my laptop.
