Hi,

I tried guiding with QHY5 today and had some trouble connecting to the camera. When the camera is freshly connected to USB INDI driver can't connect to it. After I ran qhy_ccd_test INDI driver was able to connect to the camera, but only if indiserver was run as root. Interestingly USB VID/PID changed after running qhy_ccd_test (I suppose camera does some kind of re-enumeration). I didn't notice such behavior when using QHY5 under Windows (VID?PID change). I guess running indiserver as a root isn't the best idea. Is there anything I can do to sole this problem?

Cheers,
milosz

Hi Milosz,

PID changed because it is renumerated after firmware upload. If driver can't connect unless indiserver is ran as root it probably means that you don't have correct /etc/udev/rules.d/85-qhy.rules installed.

Hi Peter,

Thanks for quick reply, but missing udev rule is not the guilty one. The camera is listed on USB as:
Bus 001 Device 015: ID 1618:0901

I installed the INDI QHY driver from sources downloaded yesterday. There is rule for that in the 85-qhy.rules:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="1618", ATTRS{idProduct}=="0901", MODE="0666"

This line appears there twice. I'm wondering if this might be a reason for misbehavior.

milosz

You are right, there is a bug in rules file generator code I will fix it tonight, but in the meantime add line like this to 85-qhy.rules file:

SUBSYSTEMS=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="296d", MODE="0666"

It is a rule for initialized camera... Peter

indiserver doesn't go to the point of sending the firmware. It stops on acquiring the USB device. Here is the lsusb output and indiserver start:

I restarted udev (and the laptop) several times after installing the driver. I suppose the rule is not activated or is conflicting with something.

milosz

Can you try

ls -l /dev/bus/usb/001/019

(or something like this, I don't have linux machine) to check if rule was activated and device is really accessible for anybody?

You don't need to use indiserver to experiment with the camera, qhy_ccd_test is using the same code just with much more verbose logging.

I think I found the guilty one. I run udeadm test and found this line.
MODE 0664 /lib/udev/rules.d/91-permissions.rules:36

Since the qhyccd.rules has the number 85 the 666 is overwritten by 91-permissions.rules. This doesn't happen for atik, which has number 99. I changed the qhyccd.rules file name to 95-qhyccd.rules and it solved the problem. I'm not sure why it had number 85 before, but you might consider number higher than 91 to fix the problem I experienced However 'proper' solution should be creating INDI group (or sth like this) and adding it to udev rules. Than user can be added to this group and permissions.rules will not overwrite the permission.

milosz

Great! Thank you, I will rename the rules file to 99-... to avoid this problem. Peter

Hello Indi community,

I have some trouble with my QHY5 camera. Nothing happen, the red light never turns on. I'm using the latest version of kstars and other libray (indi-qhy and qhy-firmware) with the mutlaqja's ppa under linux mint 16.
The command lsusb return this :

The value 0818 is missing the rules file. I had this line in the file in the uninitialized devices part :

It doesn't fix my problem. When I try indiserver indi_qhy_ccd, the command only returns :

I manage to load myself the firmware with the command fxload and the light finally turn on. The lsusb return :

Can you help me please ?

Sébastien.

Hi Sebastien, I've added PID 0818 for uninitialized camera to the driver and USB rules. You can build it from source or wait a couple of hours while it will be available on INDI PPA. Peter

Eureka. The PID/VID appears also in the source of the driver.

My QHY5 camera is working fine after the build of the trunk source. I will also ckeck the future update of the PPA.
Thank you Peter and thank you to the whole indi's team. You make a really good job.

Sébastien.

Hello,

I believe this may be a camera with a fouled address. I am unfamiliar with any QHY5 which had PID 0818. That is not to say they did not build one, but, I would suggest asking Qiu on the QHYCCD.com forum if this is a valid QHY5 address. Various addresses were used for the QHY5 depending on the geographic distribution of the camera.

As for rule 85, it used to be in the 40's, but we're getting older.

Best wishes,
Dan
