QHY5-II camera/driver was created by Rob Meades

Hi there. I have a QHY5-II which I want to use as a guide camera with indiserver, however the driver does not seem to be working for me, or possibly it isn't finding the camera. KStars/Ekos doesn't find the driver to connect to (having given Ekos the Remote Device guider name "QHY CCD"). indiserver -vvv shows me only this at startup:

$ indiserver -vvv indi_qhy_ccd
2016-04-04T18:31:59: startup: indiserver -vvv indi_qhy_ccd 
2016-04-04T18:31:59: Driver indi_qhy_ccd: pid=5009 rfd=3 wfd=6 efd=7
2016-04-04T18:31:59: listening to port 7624 on fd 4
2016-04-04T18:31:59: Driver indi_qhy_ccd: sending msg copy 1 nq 1:
<getProperties version='1.7'/>

Following the various threads in here, I have:

  • Checked that the camera does work on Windows.
  • Built/installed driver indi_qhy_ccd and libqhy (from recent source), with DEBUG, successfully.
  • Checked the VID/PID of the camera (which is 1618:0920). This PID isn't in the "MODE=0666" lines in 85-qhy.rules so I've added a new line for it there and rebooted, just in case (this doesn't appear to help).
  • Checked that no other rules file is using the same VID.
  • Tried running indiserver as root.

Does anyone have any suggestions as to other things I can I try? indiserver is running on Arch Linux on a Hummingboard II (a small board computer like a Raspberry Pi but with faster storage).

FYI, when I plug the camera in dmesg shows:

[ 1291.802331] usb 1-1.1: new high-speed USB device number 10 using ci_hdrc
[ 1291.884714] usb 1-1.1: New USB device found, idVendor=1618, idProduct=0920
[ 1291.891891] usb 1-1.1: New USB device strings: Mfr=0, Product=0, SerialNumber=0

I presume the camera is connected over USB before you start the INDI server?

It is, but I think I've found out what's up: fxload isn't packaged by default with Arch Linux. Not a particularly obvious failure and not something that appears in a log that I could find.

I've found and built fxload for armv7h and now dmesg shows the additional lines (that I saw in the other posts here where the disconnect/reconnect occurs after fxload reloads the binary):

[ 5235.035298] usb 1-1.1: USB disconnect, device number 14
[ 5236.748961] usb 1-1.1: new high-speed USB device number 15 using ci_hdrc
[ 5236.836338] usb 1-1.1: config 1 interface 0 altsetting 0 bulk endpoint 0x81 has invalid maxpacket 64
[ 5236.851168] usb 1-1.1: config 1 interface 0 altsetting 0 bulk endpoint 0x1 has invalid maxpacket 64
[ 5236.866588] usb 1-1.1: New USB device found, idVendor=1618, idProduct=0921
[ 5236.879136] usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 5236.892087] usb 1-1.1: Product: QHY5-II
[ 5236.902387] usb 1-1.1: Manufacturer: QHY-CCD

I'll get the hang of this Linux thing yet. :-)
