I have two Dell computers running Fedora 9 that have taken exception
to being nailed to the wall, and they fail to program about half of my
motes.  Each computer has 7 telosb motes attached to a USB hub, and I
get timeout errors, usually after 2 motes have been programmed
successfully.  My impression is that there is some problem with the
linux USB serial driver.  I haven't been able to find any reference
online to that though.  I have tried three different USB hubs just in
case that was the problem.

I have an older computer running Fedora Core 5 with 14 motes that
programs them just fine, same setup.

I am using this line to program the motes:
tos-bsl --telosb --slow -c $COM  -r -e -I -p $IHEX-$ID
the --slow switch seems to help a little, but I'm still getting failures.

Here is some of the errors I'm getting from dmesg:
ftdi_sio: update_mctrl Error from MODEM_CTRL urb: DTR LOW, RTS LOW
ftdi_sio: ftdi_set_termios FAILED to set databits/stopbits/parity
