I tried dfu-util -l, the board wasn't listed.
On a second box (debian squeeze) there's log messages when the usb is
connected

lsusb doesn't show anything either
that's really weird, if the kernel has recognized it and read the device
and string descriptors, it should also show up in lsusb. The
information lsusb uses is gathered by exactly those kernel log messages
above.
the red led is on after connecting, simtrace (linked
against libusb-1.0)
says "can't open USB device"
ths was running as root? can you post a 'strace -f -s1024 ./simtrace'
to see what's happening on a system call level?

However, I'm not able to write a firmware. I tried the main_simtrace.bin
that Harald posted to this list some days ago.

that's almost at the end of the dlwonload, quite strange.
You don't happen to have a compatible serial cable (T191, OsmocomBB,
...) that could be used to look at the serial console output of the
device?
Also, if you have a self-powered USB hub around (i.e. with its own power
supply), it would be interesting to see if that makes any difference.
Does anyone have an idea what else I can try to track
down the problems
and get the board up and running?
Assuming this board was bought from sysmocom, I think after a few more
experiments (see above) we will replace it with another one.
Regards,
Harald
