I have 14R SE and there are lots of issues. For me isn't the USB connectivity, but the Wifi/LAN connectivity. Their device adapters have gradually disappeared to nowhere. I suspect the internet hardware adapters have failed. Now have to resort to external WiFi adapters to work.

My S key has also broken.

This is my first Dell. I'll never buy a Dell again.

Yes still under warranty, will probably call after I get back from vacation.

So far only Dell give me so many problems in 2 months of purchasing it. Asus, Vaio, Acer... they all gave me problems only after a few years.
