[Nut-upsdev] support for newer mustek powermust model 06da:0003

Hi,

The udev rules in svn look correct to me

/etc/udev/rules.d/52_nut-usbups.rules:SYSFS{idVendor}=="0665", SYSFS{idProduct}=="5161", MODE="664", GROUP="nut"

but they just don't apply until I reboot. I first thought that
udevtrigger would have been the method to apply these changes without
reboot but the debian udev maintainer told me that manual chmod/chown
really would be the preferred solution:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=435624

Anyways, the strace output shows that after the kernel driver is
detached nut manages to claim the interface:

16040 ioctl(4, USBDEVFS_CLAIMINTERFACE, {0}) = -1 EBUSY (Device or resource busy)
16040 write(2, "failed to claim USB device, trying 2 more time(s)...\n", 53) = 53
16040 write(2, "detaching kernel driver from USB device...\n", 43) = 43
16040 ioctl(4, USBDEVFS_IOCTL, {ifno=0, ioctl_code=21782}) = 0
16040 write(2, "trying again to claim USB device...\n", 36) = 36
16040 ioctl(4, USBDEVFS_CLAIMINTERFACE, {0}) = 0

So, I'm guessing it's not a permission problem but the old mustek too
wants 8-byte reads and zero-padded 8-byte writes.

If I add phoenix_subdriver to subdriver_list

I can actually use also the old mustek UPS with the phoenix driver:
