This patch adds support for PL-2501 by adding the appropriate USB
ID's. This chip is used in several USB 'Easy Trasfer' Cables.

Now with proper sign-offs and right people in cc and unwrapped lines.
plusb driver (drivers/net/usb/plusb.c) doesn't recognize PL2501 chip.
Since PL2501 uses the same code as PL2301/PL2302 (PL2501 works in
compatibility mode with PL2301/PL2302), the fix is trivial and
attached as a patch.

Just to note: the patch is not mine, it can be found here and there on
Internet.
I've tested the patch and it works great.

Thank you.

This does not apply cleanly to my net-next tree at all.

This patch was created against linux-3.5, but it applies perfectly 
against net-next tree, i just checked..

I'm sorry for not being able to submit the correct patch from the first 
attempt (and not even from the third attempt). Could you be more specific 
about "doesn't apply cleanly at all"? By the way, i'm perfectly fine if 
you just make this trivial change by yourself and take the credit, because 
our exchange of e-mails has become 20 times bigger than the patch 
itself. Probably sending another version of this patch from my side would 
be just another waste of (your) time.

"git am your_patch" fails.
