You don't need the recovering seed when using newest version of electrum + trezor. Only the PIN.
I don't think this is an accurate statement.
Even if you can import the recovery seed, it doesn't mean you need to.
It is commonly considered more secure to keep the keys in the TREZOR and use Electrum/Mycelium/etc. as an interface to the TREZOR. This way Electrum acts as a replacement for the myTrezor web interface.

When I try to create a new wallet -->hardware wallet --> trezor, electrum simply closes. This could be because I do not have a trezor connected to my computer (I'm not sure).
Yeah I had the same problem, no trezor to plug in, so I gave up. Worse, I had about 5 HD Accounts on my trezor. The only possible way to get any coins back was using Multi-bit and then, it was only able to recover from HD account 1 - all my other coins seemed to be irretrievable.
Panic sets in of course! Tried Mycelium import, failed again... Gave Up for the night, then I (PRAISE THE LORD!) found my lost trezor device on the floor of my office the next day! It had slipped out of my bag.
Anyhow, it was a long restless night, to say the least. Now, I only have 1 HD account, and all my coins are in that, so that if it happens again, at least multi-bit will work.
Not sure if it's been fixed, but no updates to firmware on trezor since, so i'm playing it safe for now.
Also, I too use mycelium instead of mytrezor, works fantastic.
Not a big fan of the plastic build-quality of the trezor and the crappy USB cable broke very fast on me too, but otherwise, best-behaving and trusted wallet so far, I may have to get another one - I do hope they improve the quality, I would like it to be metal instead of plastic!
