I recognize your wish to solve this matter and present the future
argyll-users with a universal solution. That's why I answered your mail
about this subject. But in fact I really didn't know what I was doing.
Looking at the dev-tree I found bus/usb. With the help of man udev and
some experimenting later, the DTP94 was recognised, and my goal
achieved. But it was rather more luck than wisdom.
I hope you succeed in your efforts, but sadly this is all I can
contribute.
Looking into the libusb source, and perusing this
<http://www.mail-archive.com/avr-chat@xxxxxxxxxx/msg00902.html>
gives me the hint that the creation of the right hierarchy
in /dev is needed for udev to work.
So a udev rule like:
# DTP94
SYSFS{idVendor}=="0765", SYSFS{idProduct}=="d094", \
PROGRAM="/bin/sh -c 'K=%k; K=$${K#usbdev}; \
printf bus/usb/%%03i/%%03i $${K%%%%.*} $${K#*.}'", \
NAME="%c", MODE="666"
might be a better prospect.
Unfortunately the udev in my Linux system seems to be an early,
crippled version, and I'm unable to test any of this.
