Hi,
Thanks very much for the help. I really appreciate it.

Sorry I missed this little detail.
One thing I've noticed both on the PICDEM and the UWB (Sparkfun)
board is if I hold the button down for "boot mode" the entry listed in
"lsusb" only stays for some time. That is, I get the board in boot
mode and then keep doing "lsusb" the listing:
Bus 002 Device 027: ID 04d8:000b Microchip Technology, Inc.
shows up for about 1-3 seconds then goes away. Any ideas about
this? I'm running Debian sid:
uname -a
Linux amazonia 2.6.19.7 #1 SMP PREEMPT Wed Apr 18 22:22:29 PDT 2007 i686 GNU/Linux
If I download during this time it all works fine but once it's gone I
can't download (of course).

I built this up (with sdcc) and ran it but it doesn't seem to give
me anything on USB (it does make "lsusb" pause though). Anyone else
build it? Here are some files of importance:

I tried Piklab but when I select "sdcc" in
"settings->configure piklab->toolschains" then save, when I come back
in to "settings->configure piklab->toolschains" it's set to "gputils".
Thanks again for the help.
