Thats is, actually, very good question. For reasons unknown to me, BME replacement isn't even in cssu-devel repository, not to mention extras-devel. I just spend 10 minutes searching for current state of project, which is *hilarious*, considering how important this project is. And it was *only* 10 minutes, because i knew exactly what filenames I'm looking for. I think we need proper "repositorianisation" of it.

Anyway, here are debs:

Topic with discussion about bme-replacement is here (ironically, no link to actual debs anywhere in this topic, AFAIK):

As for USB Mode, situation looked similar, but I've found that it appeared in repos, finally. Just search for "USB Mode" package and install it - you will get status menu applet to control hostmode/peripheral. Discussion is here:

// Edit
It seems that BME Replacement have it's own wiki page (edit 2: I shouldn't be so surprised, from edits history it looks that I've written half of it ):

The problem about inability to calibrate is fixed already - at least, using latest debs from site mentioned earlier, it worksforme.
