I use a different udev rule :
# ZWO filterwheel
SUBSYSTEMS=="usb", ATTRS{idVendor}=="03c3", ATTRS{idProduct}=="1f01", MODE="0666", SYMLINK+="ZWO_EFW"

and I've seen that the symlink (which is only there for decorative purposes) may point to various things. I'm curious, can you try these udev rules and report back ?

Reboot Pi III
Kernel 4.4.38-v7+
Wed Dec 28 22:16:42 GMT 2016

Poke around
pi@astropie:~ $ dmesg | grep ZWO
[    2.890026] usb 1-1.4.2.1: Manufacturer: ZWO
[    3.251430] usb 1-1.4.2.3: Product: ZWO EFW
[    3.257686] hid-generic 0003:03C3:1F01.0001: hiddev0,hidraw0: USB HID v1.01 Device [ZW0 ZWO EFW] on usb-3f980000.usb-1.4.2.3/input0
 
pi@astropie:~ $ ls -l /dev/hidraw0
crw------- 1 root root 247, 0 Dec 28 22:14 /dev/hidraw0
pi@astropie:~ $ ls -l /dev/usb/
total 0
crw------- 1 root root 180, 96 Dec 28 22:14 hiddev0
 
pi@astropie:/lib/udev/rules.d $ grep EFW *
99-efw.rules:SUBSYSTEMS=="usb", ATTRS{idVendor}=="03c3", ATTRS{idProduct}=="1f01", MODE"0666", SYMLINK+="ZWO_EFW"
 

Note
  • The kernel recognises the EFW with hid-generic hiddev0,hidraw0
  • /dev/hidraw0 and /dev/usb/hiddev0 are created
  • Permissions have changed from root:users 0666 to root:root 0600
  • The rule that I tried is in there in /lib/udev/rules.d/99-efw.rules

I start indiserver as a normal user and try to connect to the wheel
2016-12-28T22:26:14: Connect(): EFWOpen() = 4

I start indiserver with sudo and
I can connect to the EFW and rotate the filters no problem.

I note that the symlink ZWO_EFW did NOT appear in /dev

What kernel are you using?

The rules you have looks old. asi changed the sdk at some pint and since this rule shuld be used:
KERNEL=="hidraw*", ATTRS{idVendor}=="03c3", ATTRS{idProduct}=="1f01", GROUP="users", MODE="0666"

Please try and report please!

Rumen

Many kudos for the contributions to the driver, lin_guider etc.

Thanks for the suggestion about the rules.

Hans suggested the old rules as they are working for him.

I was already using those new rules from the SDK and the posts above but the problem was that I had to use sudo to run indiserver otherwise the efw wheel wouldn't work EFOpen() = 4.

I also noticed that /dev/usb/hiddev0 and /dev/hiddraw0 disappear after using the wheel with sudo indiserver. ( With the new rules)

Stranger still I can use the wheel with the demo program from the SDK, as an ordinary user.

Weird.

Hi procras. I got my ZWO EFW 7 slot yesterday, and had same problem as you (must run with sudo).

I tried everything in this thread, and noting worked. I did however notice the KERNEL=="hidraw*" and remembered I had issues getting a USBRelay hid device working a while back. So I copied the rule from that device, and now it works without sudo :)

It only works when starting with
indiserver indi_asi_wheel
and not by starting local from ekos, but I never use that anyways.

Try this:
1. rebuild indi-asi (this replaces changes you have made with original udev rules)
2. remove /etc/udev/rules.d/99-asi.rules and /etc/udev/rules.d/99-efw.rules (if you moved anything to /etc)
3. edit /lib/udev/rules.d/99-efw.rules
3.1. komment out or remove:
KERNEL=="hidraw*", ATTRS{idVendor}=="03c3", ATTRS{idProduct}=="1f01", GROUP="users", MODE="0666"
3.2. add:
ACTION=="add", ATTR{idVendor}=="03c3", ATTR{idProduct}=="1f01", MODE="0666"
4. Just to be sure reboot with EFW attached (could probably just reload udev rules)
5. run
indiserver indi_asi_wheel
6. connect EKOS to localhost with default port.

This worked for me on two recently installed Kubuntu systems.

Good luck, Magnus :)

Hi Magnus,
can you please paste the output of "lsusb" with the 7 slot EFW plugged. I doubt both 5 and 7 slot wheels share the same product ID....

Well, I had to check... But it's the same.
I had just guessed it is the same because the ZWO site says it is the same driver for both. The driver could have checked what dev id was connected, but as the hardware part (controller and motor) is the same, then it's virtually the same device.

// Edit: The 7 slot 36mm FW also comes in a 8 slot 1.25" version, and on the ZWO site someone asked if they could by the carousel and convert it. The answer was yes.

Will the filter carousel be available separately? If I purchase the 8×1.25″ version as a started, is it possible to purchase only the carousel if I should upgrade to 36mm filters?

The answer was actually:
of course, the 36mm filter will be provide separately
So not sure if I would try :huh:

This is quite strange but they do share the same product ID.
So my theory was wrong and the same rule should work for both versions.

Hi Rumen and Magnus,

I am please to say that if I use the rule

ACTION=="add", ATTR{idVendor}=="03c3", ATTR{idProduct}=="1f01", MODE="0666"

for my ZWO EFWmini that I can use the wheel by running indiserver as a normal user.

This is on the desktop, I will also try on my Pi III and let you know. :-)

Would be nice if anyone that has everything working would try with
ACTION=="add", ATTR{idVendor}=="03c3", ATTR{idProduct}=="1f01", MODE="0666"

If it works for everyone, then perhaps it's a more suited rule for the repository?

Once someone confirms that it works on raspbian I will add it. however maybe there is no group users on raspbian, I was thinking can someone try this one:
KERNEL=="hidraw*", ATTRS{idVendor}=="03c3", ATTRS{idProduct}=="1f01", MODE="0666"

I have tried the new rule on my raspberry Pi III. It also works :-))

I put the rule into my /etc/udev/rules.d/99-observatory.rules as
# Filter Wheel
ACTION=="add", ATTR{idVendor}=="03c3", ATTR{idProduct}=="1f01", MODE="0666"

Called udevadm
$ sudo udevadm control --reload-rules

Started indiserver as my normal user on the pi
$ indiserver -v indi_asi_wheel

Then connected Ekos from kstars on my destop maching and changed the filter around. No more of that
horrible EFWOpen() message.

The kernal recognises the device as hid
[ 20.269755] hid-generic 0003:03C3:1F01.0001: hiddev0,hidraw0: USB HID v1.01 Device [ZW0 ZWO EFW] on usb-3f980000.usb-1.3/input0
But using the rule from the SDK

# FILTER WHEELS
KERNEL=="hidraw*", ATTRS{idVendor}=="03c3", ATTRS{idProduct}=="1f01", GROUP="users", MODE="0666"
Does NOT work.

While

# Filter Wheel
ACTION=="add", ATTR{idVendor}=="03c3", ATTR{idProduct}=="1f01", MODE="0666"
Works great

I have tried this on my Desktop (Arch system) and my raspberry PI III, (Jessie with raspberry PI download)

I am at a loss to explain why the hidraw rule is working on some systems and not on others.
While I was trying to get the wheel to work with the hidraw rule I noticed;
  • Worked fine if I ran indiserver as root
  • Worked fine from the demo program (SDK toolkit) as a normal user
  • hidev0 and hidraw0 links in /dev/ disappeared when I ran the wheel with sudo indiserver
