The best resource for getting started, to my knowledge, is the FAQ on the Wiki:
http://ettus-apps.sourcerepo.com/redmine/ettus/projects/usrpe1xx/wiki/FAQ

What do you mean by "linux is ... too slow"? The E100 operates using
an OMAP3 processor - it isn't going to be nearly as fast as a PC, if
that's what you mean. In terms of embedded devices, I have had no
trouble with the E100 'acting slow'.

I'm not sure about it returning 0xffffffff, but the first thing I
would try is updating the FPGA firmware:

No, UHD is not currently in the opkg repositories, so this isn't
possible at the moment.
