Libreboot: weird USB problems

Hi, I have some problems with using USB pendrives. I tested this on two machines, Thinkpad T500 and T400, both with libreboot installed. First, copying files to them seems to be very slow. Sometimes 15mb/s, sometimes it goes quite fast but then holds for seconds/minutes. Then, copying-processes seem to never finish. The files end up being corrupted. Rsync doesn't work at all (idles forever on creating the transfer-list). I used Kingston pendrives.
Anyone else ran into these issues?
A different USB issue, pasted from one of my older posts:
Personally, I found out that a USB external audio card being plugged in on boot prevented Libreboot from starting up on an X200 (docked, at least).
I need to unplug it, and plug it back before unlocking the drive the second time (you know, having to put the same passphrase twice).
Note that I got rid of pulseaudio and strictly use alsa and jack (via qjackctl and alsamixer).
I'll tell the Libreboot team when I'll figure out how to get back on their IRC node (last time I was banned (automatically) because I pasted some logs massively (I thought it would make one post instead of one per line... ).
In case anyone stumbles over the same issue: I couldn't fix the problem with slow datatransfer but the problem with corrupted data. The problem was that I simply unmounted USB drives before pulling them out (via context-menu). However, this is not enough. One should sync it and make sure that there are no read-write processes running. Unmount/ejecting is not the same as "securely remove".
This seems more like a problem with operating system or its behavior on your hardware. Or maybe even a hardware problem (either a buggy southbridge or dying USB drives). Does not seem to be a Libreboot problem - because, after booting through the initial stage, Libreboot gives a complete control over the initialized hardware to the operating system. Try using the latest Ubuntu LiveCD and another flash drive, to see if you still have this problem
