Hi, So far the latest build works fine, but unfortunately I noticed that transfer speed through my J-Link (http://www.segger.com/jlink.html) went down to a ca. 830 bytes/sec. With the old (3106) build it used to be ca. 1,2 KB/sec (which isn't that fast either, it should be at least 3 kb/sec with the target I am using). At least FTDI USB2serial Adapters seems to work without problems (anyone tried a Prolific one?) Anyone else noticed something similar? Those gadgets are really important to me, since I use Parallels mainly for embedded development stuff. While Parallels really rocks USB support is really one of the biggest annoyances with the product (alhough I acknowledge we've seen lots of improvements here since the last stable build)
