Well. As I am crazy about trying to get the best out of my devices/new features, I tried the alternative firmware for the Sony PRS-300 that is out (listed in Sony Dev section on Mobileread I believe). After, whether I am booted into the Sony software or not, it breaks communication somehow with the Sony Reader.....
I get, when plugging it in, "Error communicating with this device"
and this:
oneType' object has no attribute 'xpath'

Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 65, in run
File "site-packages\calibre\gui2\device.py", line 272, in _books

File "site-packages\calibre\devices\prs505\sony_cache.py", line 89, in __init__
AttributeError: 'NoneType' object has no attribute 'xpath'

So, I figure, while the software isn't that fabulous, it certainly isn't enough to make me give up my calibre! Working on resetting the reader now....
p.s. I have another one (girlfriends) and hers connects up just fine, and that is the only difference I can figure, so......
